Art. XVII.—On some Foraminifera and Ostracoda obtained off Great Barrier Island, New Zealand. By Frederick Chapman, A.L.S., F.R.M.S., Palæontologist, National Museum, Melbourne. [Read before the Wellington Philosophical Society, 2nd August, 1905.] Plate III. Introductory Remarks. The following series of Foraminifera and Ostracoda was obtained from material collected during the dredging operations carried out by Messrs Hedley and Suter, under the auspices of the Australasian Association for the Advancement of Science, at the Dunedin meeting in 1904. The sounding from which the microzoa were selected was taken in lat. 36° 8′ S., long. 175° 55′ E., off Great Barrier Island, North Island New Zealand, at a depth of 110 fathoms. This locality is not far from the “Challenger” station 169, where at a depth of 100 fathoms the water had a temperature of 55·2°.* Chall. Reports, Summary of Results, ptai, 1895, p. 605. At this station, at a depth of 700 fathoms, sixty-six species of Foraminifera, but no Ostracoda, were recorded. Of the Foraminifera, twenty-eight species are common to both localities, after making allowance for changes in some of the specific names of the earlier record. The Ostracoda are dealt with in detail in the sequel to this paper. The sounding off Great Barrier Island is remarkable for the extraordinary abundance of specimens of Biloculina, Nodosaria, Cristellaria, and Truncatulina, and their full development is indicative of especially favourable conditions of life in that particular area. Another interesting feature of the present assemblage of Foraminifera is the presence of a large number of forms which have hitherto been found in the Northern Hemisphere; and particularly from the colder waters of the Temperate Zone. The following is a list of the Foraminifera embodied in this report; the species new to the New Zealand area, according to the list given in Captain Hutton's “Index Faunæ Novæ-Zealandiæ,” being marked with an asterisk. Of the 103 species of Foraminifera enumerated, fifty-seven are new to this area, whilst one is new to science, and constitutes the type of a new genus Biloculina pisum Schlumberger.

Order Foraminifera. Family Miliolidæ. Subfamily Miliolininæ. Genus Biloculina, d'Orbigny. Biloculina pisum, Schlumberger. Biloculina pisum, Schlumberger, 1891, Mém. Soc. Zool. France, vol. iv, p. 569, pl. xi, figs. 81–83; text-figure 31. This species is hardly distinguishable in external appearance from the nearly allied B. vespertilio, Schlumberger,* Op. supra cit., p. 561 and B. bradii, Schl.Op. supra cit., p. 557; the shape of the aperture being one of the characters which separate it. Upon slicing the tests, however, the identity of our specimens with the above, B. pisum, is at once apparent, since the internal arrangement of the chambers in their relation to one another, especially at the point of incurvation and fusion to the previous chamberwall, is characteristic of this species and B. comata, Brady.‡ Rep. Chall., vol. ix, 1884, p. 144, pl. iii, figs. 9 a, b. The latter species is distinguished by its externally striated shell-surface; the arrangement of the initial series of chambers is also different, and the wall of the first chamber in B. comata (form A) is thick, whilst in B. pisum (form A) it is very thin. The original locality given by Schlumberger for B. pisum is the Mediterranean. Although this form is quite common in the present series, the tests all appear to belong to the megalospheric type of shell (form A), as Schlumberger also found. Biloculina anomala, Schlumberger. Biloculina anomala, Schlumberger, 1891, Mém. Soc. Zool. France, vol. iv, p. 569, pl. xi, figs. 84–86; pl. xii, fig. 101; text-figures 32–34.

This species was found by Schlumberger in dredgings from the Mediterranean, at a depth of 555 meters. A solitary specimen, agreeing in all external characters with the above, is found in our series. Genus Miliolina, Williamson. Miliolina insignis, Brady. Miliolina insignis, Brady, 1884, Rep. Chall., vol. ix, p. 165, pl. iv, figs. 8, 10. This species is fairly common in the present series. It attains the unusual length of 3 mm. M. insignis has a wide distribution and a great range in depth. One of the localities in which it has previously been found is Bass Strait, 150 fathoms. Miliolina circularis, Bornemann sp. Triloculina circularis, Bornemann, 1855, Zeitschr. d. deutsch. geol. Gesellsch., vol. vii, p. 349, pl. xix, fig. 4. Miliolina circularis, Born. sp., Millet, 1898, Journ. R. Micr. Soc., p. 499, pl. xi, figs. 1–3. Only one example of this form occurs in our series, and this is fairly typical. Millett's specimens were obtained from the Malay Archipelago. Egger records it (“Gazelle” Exped.) from two stations off the Australian coast, and the “Challenger” obtained it in Bass Strait. Miliolina seminulum, Linné sp. Serpula seminulum, Linné, 1767, Syst. Nat., 12th ed., p. 1264, No. 791. Miliolina seminulum, Linné sp., Brady, 1884, Rep. Chall., vol. ix, p. 157, pl. v, figs. 6 a-c. One small but otherwise typical example of this widely distributed form occurs in our series. Miliolina vulgaris, d'Orbigny sp. Quinqueloculina vulgaris, d'Orbigny, 1826, Ann. Sci. Nat, vol. vii, p. 302, No. 33. Q. vulgaris, d'Orb., Schlumberger, 1893, Mém. Soc. Géol. France, vol. vi, p. 207. pl. ii, figs. 65, 66; woodcuts, figs. 13, 14. As a recent species this is usually recorded under the name of Miliolina auberiana, d'Orb sp. Its nearest geographical occurrence to the present one is in the Malay Archipelago, where it was found by Millett. It is also an abundant form in the Tertiary deposits of Australia. In the present series it is not uncommon.

Miliolina bicornis, Walker and Jacob sp. Serpula bicornis, Walker and Jacob, 1798, Adams Essays, Kanmacher's ed, p. 633, pl. xiv, fig. 2. Miliolina bicornis, W. and J. sp., Goes, 1894, K. Svenska Vet.-Akad. Handlingar, vol. xxv, p. 113, pl. xxi, figs. 860, 861. Occasional examples of the above species were met with in the present material. It is a widely distributed form, and is most abundant in quite shallow water, the depth at which the present soundings were taken, 110 fathoms, being near the deepest limit of its occurrence. Miliolina agglutinans, d'Orbigny sp. Quinqueloculina agglutinans, d'Orbigny, 1839, Foram. Cuba, p. 168, pl. xii, figs. 11–13. Miliolina agglutinans, d'Orb. sp., Goes, 1894, K. Svenska Vet.-Akad. Handl., vol. xxv, p. 110, pl. xix, fig. 848, and plate xx, fig 849. Only one typical example of this widely distributed species occurred in this series. Subfamily Hauerininæ. Genus Planispirina, Seguenza. Planispirina sphæra, d'Orbigny sp. Plate III, figs. 1 a, b. Biloculina sphæra, d'Orbigny, 1839, Foram. Amér. Mérid., p.66, pl. viii, figs. 13–16. Brady, 1884, Rep. Chall., vol. ix, p. 141, pl. ii, figs. 4 a, b. Planispirina sphæra, d'Orb. sp., Schlumberger, 1891, Mém. Soc. Zool. France, vol. iv, p. 577, text-figures 45, 46. The examples in the present collection all show the normal V-shaped aperture, with one exception; this is of larger dimensions, and has a labyrinthic orifice (see figure). The smaller specimens have diameters ranging from 0·425 mm. to 0·8 mm., whilst the specimen with a labyrinthic aperture has a diameter of 1·4 mm. This species, although never very abundant, is well distributed both as to geographical range and depth. It has already been recorded from this locality at station 169 (“Challenger”).

Family Astrorhizidæ. Subfamily Astrorhizinæ. Genus Pelosina, Brady. Pelosina cylindrica, Brady. Pelosina cylindrica, Brady, 1884, Rep. Chall., vol. ix, p. 236, pl. xxvi, figs. 1–6. The occurrence of this species at a depth of only 110 fathoms is interesting, since in the “Challenger” dredgings it was an essentially deep-water form; the least depth at which it was found was 620 fathoms. It was also recorded from the “Challenger” station 169, in 700 fathoms. The “Gazelle” expedition obtained this species, however, at 82–86 meters (44 to 47 fathoms), from Western Australia. Our specimens are typical, and of the normal size. The walls of the test are formed of a fine grey calcareous mud. Somewhat common. Pelosina variabilis, Brady. Pelosina variabilis, Brady, 1879, Quart. Journ, Micr. Sci., vol. xix, n.s., p. 30, pl. iii, figs. 1–3. This interesting form is rare in our series. It was found in the “Challenger” dredgings at station 169, near to the present locality, at a depth of 700 fathoms. Pelosina rotundata, Brady. Pelosina rotundata, Brady, 1879, Quart. Journ. Micr. Sci., vol. xix, n.s., p. 31, pl. iii, figs. 4, 5. The specimens found in our samples are not so evenly shaped as usual, but there seems to be no doubt of their identity with the above species. The “Challenger” soundings from near this locality have yielded the same species at a depth of 700 fathoms. Subfamily Rhabdammininæ. Genus Brachysiphon, gen. nov. (Deriv.—βρaχvs, short; σíφων, a tube). Generic Characters.—Test tubular, short, open at both ends or closed at one; consisting of an inner chitinous tube incrusted with sand-grains or small foraminiferal tests, as Globigerina, in the only species at present known. Aperture more or less circular, bordered by the thickened chitinous lining of the interior.

Brachysiphon corbuliformis, sp. nov. Plate III, figs. 2 a, b, 3. Description.—Test roughly cylindrical, short; orally depressed, also basally when double-apertured; irregular in outline; composed of sand-grains and tests of other Foraminifera, as Globiqerina, cemented to a brown chitinous base or internal lining. Aperture more or less circular. Dimensions.—About 0·8 mm. In diameter. Aperture about 0·28 mm. across. This species reminds one of Profeonina difflugiformis, Brady sp., var. testacea, Flint,* Rep. U.S. Nat. Mus. for 1897 (1899), p. 273, pl. xvi, fig. 1. in its general appearance It differs morphologically, however, in having a cylindrical cavity instead of an inflated chamber. Rather common. Off Great Barrier Island, New Zealand, 110 fathoms. Family Lituolidæ. Subfamily Lituolinæ. Genus Reophax, Montfort. Reophax scorpiurus, Montfort sp. Reophax scorpiurus, Montfort, 1808. Conchyl. Systém., vol. i, p. 330, 83e genre Brady, 1884, Rep. Chall., vol. ix, p. 291, pl. xxx, figs. 12–17. Only two specimens of this widely distributed form occur in our series. The test, in each example, is formed of loosely cemented sand-grains. One specimen has a blunt termination, whilst the other gradually tapers to a point. Genus Haplophragmium, Reuss. Haplophragmium canariense, d'Orbingny sp. Nonionina canariensis, d'Orbigny, 1839, Foram. Canaries, p. 228, pl. ii, figs. 33, 34. Haplophragmium canariense, Brady, 1884, Rep. Chall, vol. ix, p. 310, pl. xxxv, figs. 1–5. Several very fine and typical specimens occur in this dredging. Their tests are of a yellow to a ruddy-brown colour, and their texture somewhat coarsely arenaceous. It is a widely distributed form in recent deposits. Haplophragmium globigeriniforme, Parker and Jones sp. Lituola nautiloidea, var. globigeriniforme, Parker and Jones, 1865, Phil. Trans., vol clv, p. 407, pl. xv, figs. 46, 47. Haplophragmium globigeriniforme, P. and J. sp., Brady, 1884, Rep. Chall., vol. ix, p. 312, pl. xxxv, figs. 10, 11.

Brady regards this species as essentially of deep-water habitat, and it is consequently not surprising to find it but rarely in the sounding off Great Barrier Island. One of the specimens was accidentally broken. and showed the test to be very thin, and formed of almost uniform sand-grains very neatly cemented, and having a smooth surface both on the interior and exterior. In our specimen the chambers increase very rapidly in size with growth. H. globigeriniforme has been recorded from the “Challenger” sta. 169, at 700 fathoms. Haplophragmium clacareum, Brady. Haplophragmium calcareum, Brady, 1884, Rep. Chall., vol. ix, p. 302, pl. xxxiii, figs. 5–12. A typical specimen occurs in our series. It is almost entirely a tropical species, an exception occurring, in the “Challenger” records, off Sydney, 410 fathoms. Subfamily Trochammininæ. Genus Ammodiscus, Reuss. Ammodiscus tenuis, Brady. Ammodiscus tenuis, Brady, 1881, Quart. Journ. Micr. Sci., vol. xxi, n.s., p.51. Id., 1884, Rep. Chall., vol. ix, p. 332, pl. xxxviii, figs. 4–6. The form distinguished as A. tenuis occurs with some frequency in our sounding. It has been previously recorded,* Rep. Chall., Summary of Results, vol. i, 1895, p. 605. in company with A. incertus, d'Orb., from a neighbouring locality—station 169; and Dr. Brady, indeed, threw out the suggestion that the form was perhaps only a local variety of the better-known and ubiquitous species A. incertus. Dr. Rhumbler has also remarked about this species,† Archiv für Protistenkunde, vol. iii, 1903, p. 281. “Die Scheibe ist dunner, die welcher sie vielleicht die megalosphirische Form darstellt.” A general examination of our specimens showed the initial portion of the coil in every case to commence with a more or less swollen “protoconch” or (?) megalosphere. This is subject to much variation in size, which at first seemed to lend support to the idea that a microsphere might be present in A. tenuis. To conclusively settle this doubtful point, however, it will necessitate the examination of a further series of specimens.

The initial portion of the shell is subspheroidal, and seems to be merely an inflation of the tubular part of the shell. The dimensions of some of the initial chambers in their longest diameter are as follows: Specimens figured by Brady—360μ and 300μ. From the present series—100μ, 75μ, 50μ. Family Textularidæ.

It is interesting to meet with this species off Great Barrier Island, since it is rare in the recent condition. It has only been observed previously off Culebra Island, 390 fathoms, and off the coast of South America, south-east of Pernambuco, 350 fathoms.

The recent examples are better known under the name of T. aspera, Brady, which is, however, identical in its essential characters with the earlier-described T. tuberosa. Our specimens have the ruddy-brown tests similar in colour to the examples found in North Atlantic. Genus Spiroplecta, Ehrenberg. Spiroplecta sagittula, Defrance sp. Textularia sagittula, Defrance, 1824, Dict. Sci. Nat., vol. xxxii, p. 177; 1828, vol. liii, p. 344; Atlas Conch., pl. xiii, fig. 5. Spiroplecta sagittula, Defr. sp., J. Wright, 1891, Proc. R. Irish Acad., p. 471. This species and the following variety attain to a great length in this deposit, some of the specimens measuring 4 mm. T. sagittula was found off the coast of New Zealand (sta. 169) by the “Challenger.” Spiroplecta sagittula, Defr. sp., var. fistulosa, Brady. Plate III, fig. 4. Textularia sagittula, Defr., var. fistulosa, Brady, 1884, Rep. Chall., vol. ix, p. 362, pl. xiii, figs. 19–22. This variety is much more abundant in the present series than the specific form, and attains approximately the same length. Genus Clavulina, d'Orbigny. Clavulina communis, d'Orbigny.

This species is not at all common, but typical specimens occur, measuring about 3 mm. in length. It has been already recorded form the Southern Ocean, and is more commonly found in the Southern Hemisphere. Clavulina rudis, Costa sp. Glandulina rudis, Costa, 1857, Mem. R. Acc. Sc.

Clavulina soldanii, J. and P. sp., Goes, 1896, Bull. Mus. Comp. Zool. Harvard, vol. xxix, No. 1, pt. xx, p. 37, pl. iv, figs. 39–46. Goes has shown that certain slender forms of this species exhibit a definite valvuline aperture, whilst others have a modified labyrinthic opening. Our specimens clearly display the valvuline character of the aperture. Not uncommon. Subfamily Bulimininæ. Genus Bulimina, d'Orbigny. Bulimina pyrula, d'Orbigny.

This widely distributed form is abundant in the sounding off Great Barrier Island. Bulimina inflata, Seguenza. Bulimina inflata, Seguenza, 1862, Atti Accad. Gioenia Sci. Nat, ser. 2, vol. xviii, p. 109, pl. i, fig. 10. Millett, 1900, Journ. R. Micr. Soc., p. 279. The above species has a somewhat wide distribution. It is rather unusual to find it at a depth of only 100 fathoms, as it is a fairly deep-water species. A single specimen occurred in our series. Genus Virgulina, d'Orbigny. Virgulina subsquamosa, Egger. Virgulina subsquamosa, Egger, 1857, Neues Jahrb. für Min., &c., p. 295, pl. xii, figs. 19–21. Brady, 1884, Rep. Chall., vol. ix, p. 415, pl. hi, figs. 7–11. This species is rather abundant in the present sounding. It does not appear to have been found before in this locality. It has been recorded, however, form station 165B (“Challenger”) between Sydney and New Zealand. Genus Bolivina, d'Orbigny. Bolivina robusta, Brady. Bolivina robusta, Brady, 1884, Rep. Chall., vol. ix, p. 421, pl. liii, figs. 7–9. Millett, 1900, Journ. R. Micr. Soc., p. 543. Our specimens are rather small, but otherwise typical. It is apparently new to this particular area.

Micr. Soc., p. 546. The finer washings from the sounding off Great Barrier Island have yielded this species in abundance. It is new to the New Zealand area. Among other places recorded are Western Australia by Egger (‘Gazelle”) at 359 meters, and from the Malay Archipelago by Millett. Subfamily CAssidulininæ. Genus Cassidulina, d'Orbigny.

Nuovi Lincei, vol. xii, p. 103, pl. ii, fig. 10. Two specimens were found in our series The species has a wide distribution, and has been found in the Southern Ocean as far as the Antarctic ice-barrier (Brady). Cassidulina subglobosa, Brady. Cassidulina subglobosa, Brady, 1881, Quart, Journ. Micr. Sci., vol. xxi, n.s.,p.60. Id. 1884, Rep. Chall., vol. ix, p. 430, pl. liv, figs. 17 a-c. This species has already been recorded from the South Pacific, and also from the Southern Ocean. It is not infrequent in the present collection. Cassidulina bradyi, J. Wright. Cassidulina bradyi (Norman. MS.), J Wright, 1880. Proc. Belfast Nat. Field Club, Appendix, p. 152. C. bradyi, Norman, H. B. Brady, 1884, Rep. Chall., vol. ix, p. 431, pl. liv, figs. 6–10. This species has always been referred to on the authority of Norman. The first published reference to it, however, was by Joseph Wright, who described it as “a crozier-shaped Cassidulina.” Several examples of this pretty speices occur in our series. It has been found in the South Pacific, but does not seem to have previously occurred near the present locality.

Lagena hexagona, Williamson sp., Millett, 1901, Journ. R. Micr. Soc., p. 8. A single typical specimen of this elegant form occurs in our material. Lagena lacunata, Burrows and Holland. Lagena lacunata, Burrows and Holland, 1895, in Jones's Palæont. Soc. Mon., Crag. Foram., pt. ii, p. 205, pl. vii, fig. 12. This species is distinguished from the better-known L. castrensis, Schwager, by the depressions on the faces of the test. Millett regards both of these forms, perhaps rightly, as one variety of L. Orbignyana. L. lacunata is not uncommon in our soundings. Subfamily Nodosariinæ. Genus Nodosaria, d'Orbigny. Nodosaria hispida, d'Orbigny. Nodosaria hispida, d'Orbigny, 1846, Foram. Foss. Vienne, p. 35, pl. i, figs. 24, 25. Egger, 1899, Abhandl. k. bayer. Akad. Wiss., cl. ii, vol. xxi, p. 79, pl. ix, figs. 23, 24. This is a very variable form, the only constant character being the hispid surface of the test. A single specimen was found off Great Barrier Island, which consists of two closely conjoined chambers with short, coarse prickles. N. hispida has been met with in the South Pacific, but not very near the present locality. Nodosaria pyrula, d'Orbigny. Nodosaria pyrula, d'Orbigny, 1826, Ann. Sci. Nat., vol. vii, p. 253, No. 13. Flint, 1899, Rep. U.S Nat. Mus. (1897), p. 309, pl. lv, fig. 4. Millett, 1902, Journ. R. Micr. Soc., p. 514. Three specimens of this sparingly distributed form occur in our series. In each case the last chamber of the test is seen to contain a reddish-brown substance which is probably of the nature of dried protoplasm. N. Pyrula has been recorded from various observing-stations in the South Pacific, but not from the present locality.

Subgenus Dentalina, d'Orbigny. Nodosaria (Dentalina) consorbrina, d'Orbigny sp. Dentalina consobrina, d'Orbigny, 1846, Foram. Foss. Vienne, p. 46, pl. ii, figs. 1–3. Nodosaria (D.) consobrina, d'Orbigny sp., Brady, 1884, Rep. Chall., vol. ix, p. 501, pl lxii, figs. 23, 24. A single specimen was found in our sample. Nodosaria (D.) consobrina, d'Orb. sp., var. emaciata, Reuss. Dentalina emaciata, Reuss, 1851, Zeitschr. d. deutsch. geol. Gesellsch., vol. iii p. 63, pl. iii, fig. 9. Nodosaria (D.) consobrina, d'Orb. sp., var. emaciata, Reuss, Brady, 1884, Rep. Chall., vol. ix, p. 502, pl. lxii, figs. 25, 26. This slender variety is more common than the type form in the present series. It has already been recorded from the South Pacific. Nodosaria (D.) filiformis, d'Orbigny. Plate III, fig. 5. Nodosaria filiformis, d'Orbigny, 1826, Ann. Sci. Nat., vol. vii, p. 253, No. 14. Flint, 1899, Rep. U S. Nat. Mus. (1897), p. 310, pl. lv, fig. 6. This species is distinguished by its long, slender, recurved test, with oval segments. It is not uncommon in the present series. Some of the specimens have a bulbous commencement, whilst others have the extremity attenuated and finely pointed. The latter variation agrees with the form figured by d'Orbigny under the name of Dentalina elegans. N. (D.) filiformis has been recorded from the South Pacific, but not from the neighbourhood of Great Barrier Island. Nodosaria (D.) farcimen, Reuss sp. Dentalina farcimen, Reuss (after Soldani), 1863, Bull. Acad. Roy. Belg., ser. 2, vol. xv, p. 146, pl. i, fig. 18. Nodosaria farcimen, Soldani sp. Flint, 1899, Rep. U.S. Nat. Mus. (1897), p. 309, pl. lv, fig. 5. One specimen of this universally distributed form found in our series. Nodosaria (D.) soluta, Reuss sp. Dentalina soluta, Reuss, 1851, Zeitschr. d. deutsch. geol. Gesellsch., vol. iii, p. 63, pl. vii, fig. 4. Nodosaria soluta, Reuss sp, Flint, 1899, Rep U.S. Nat. Mus. (1897), p. 310, pl. lvi, fig. 3. Millett, 1902, Journ. R. Micr. Soc., p. 516.

This species is not uncommon in the present series. Its occurrence at 110 fathoms off Great Barrier Island is in accordance with Dr. Brady's remark that in the South Pacific this species affects shallower water than in other localities. N. (D.) soluta has been recorded from the “Challenger” station 169 by Dr. Brady. Nodosaria (D.) pauperata, d'Orbigny sp. Dentalina pauperata, d'Orbigny, 1846, Foram. Foss. Vienne, p. 46, pl. i, figs. 57, 58. Nodosaria (D.) pauperata, d'Orb. sp., Brady, 1884, Rep. Chall., vol. ix, p. 500, woodcuts, figs. 14 a-c. This species is fairly typical, and occurs frequently in our series. Nodosaria (D.) roemeri, Neugeboren sp. Dentalina roemeri, Neugeboren, 1856, Denkschr. d. k. Akad. Wiss. Wien, vol. xii, p. 82, pl. ii, figs. 13–17. N. (D.) roemeri, Neug. sp., Brady, 1884, Rep. Chall., vol. ix, p. 505, pl. lxiii, fig. 1. This form has been recorded by Brady as being chiefly found in the North Atlantic, at depths of less than 1,000 fathoms. It is therefore the more interesting to meet with it in the present sounding off Great Barrier Island at 110 fathoms, where it is not uncommon. Nodosaria (D.) obliqua, Linné sp. Nautilus obliquus, Linné, 1767, Syst. Nat., 12th ed., p. 1163, 281; 1788, Ibid, 13th (Gmelin's) ed, p. 3372, No. 14. Nodosaria (D) obliqua, Linné sp, Brady, 1884, Rep.

This is one of the most noteworthy species of Foraminifera in the present series, and is here very abundant. It is not uncommon to find specimens reaching the extraordinary length of 9·5mm. Some of the shells are rather irregular in growth, and tend to become sinuous N. (D.) obliqua has been previously recorded from “Challenger” station 169, near the present locality. Nodosaria (D.) obliqua, L. sp., var. vertebralis, Batsch var. Plate III, fig. 5. Nautilus (Orthoceras) vertebralis, Batsch, 1791, Conchyl. des Seesandes, p. 3, No. 6, pl. ii, figs. 6 a, b.

That this form is only a variety of N. obliqua is clearly demonstrated by the present series of specimens. Indeed, it is somewhat difficult to satisfactorily separate the variety from the species in some cases. Genus Frondicularia, Defrance. Frondicularia reussi, Karrer. Plate III, fig. 7. Frondicularia reussi, Karrer, 1862, Sitzungsb. d.k. Ak. Wiss. Wien, vol. xliv, p. 441, pl. i, fig. 1. Three examples of an ovate, striated Frondicularia were found off Great Barrier Island. They are almost exactly matched by Karrer's figured specimen, from the Miocene of the Vienna basin. The narrowest of our specimens may also be compared with Karrer's F. Sculpta, figured on the same plate as the above. These shells are obviously of the same type as the earlier-described F. annularis of d'Orbigny,* Foram. Foss. Vienne, 1846, p. 59, pl. ii, figs. 44–47. from the Miocene of Baden; this, however, is a generally broader form. This appears to be the first occurrence of F. reussi in recent deposits. Genus Marginulina, d'Orbigny. Marginulina glabra, d'Orbigny. Marginulina glabra, d'Orbigny, 1826, Ann. Sci. Nat., vol. vii, p. 259, No. 6; modèle No. 55. Brady, 1884, Rep.

Chall., vol. ix, p. 535, pl. lxvi, figs. 21–23. Chapman, 1895, Proc. Zool. Soc. Lond., p 33. A characteristic example of this elegant little cristellarian was found in our sounding. It has also been recorded from

two places off the west coast of New Zealand, at 150 and £275 fathoms(Brady). Cristellaria reniformis, d'Orbigny. Cristellaria reniformis, d'Orbigny, 1846, Foram. Foss.

(1897) p. 315, pl. lxii, fig. 2. A single example was found in the present sounding. This species has been previously recorded from the South Pacific, but is always found sparingly. Cristellaria schloenbachi, Reuss. Cristellaria schloenbachi, Reuss, 1862, Sitzungb. d. k. Ak. Wiss Wien, vol. xlvi, p. 65, pl. vi, figs. 14, 15. Brady, 1884, Rep. Chall., vol. ix, p. 539. pl. lxvii, fig. 7. Millett, 1903, Journ. R. Micr. Soc., p. 253. One fine example was found in our material. The nearest recorded localities to the present appear to be Raine Island and the Malay Archipelago. Cristellaria tricarinella, Reuss. Cristellaria tricarinella, Reuss, 1862, Sitzungsb. d. k. Ak. Wiss. Wien, vol. xlvi, p. 68, pl. vii, fig. 9; pl. xii, figs. 2–4. Egger, 1893, Abhandl. K. bayer. Ak. Wiss., cl. ii, vol. xviii, abth. ii, p. 159, pl. xii, figs. 28, 29. This interesting cristellarian is fairly common in the present series. The “Challenger” records are all in the Pacific, one locality being off the west coast of New Zealand, at 150 fathoms. Egger records this species from Mauritius, and off the west coast of Australia (“Gazelle”). Cristellaria italica, Defrance sp. Saracenaria italica, Defrance, 1824, Dict. Sci. Nat., vol. xxxii, p. 177; 1827, vol. xlvii, p. 344; Atlas Conch., pl. xiii, fig. 6. Cristellaria italica, Defr. sp., Flint, 1899, Rep U.S. Nat. Mus. (1897), p. 316, pl. lxiii, fig. 6. Millett, 1903. Journ. R. Micr. Soc., p. 256. Several specimens were selected from our sample. It has a rather wide distribution, but it is never very common. It was found at four “Challenger” stations in the South Pacific.

Cristellaria latifrons, Brady. Cristellaria latifrons, Brady, 1884, Rep. Chall., vol. ix, p. 544, pl. lxviii, fig. 19; pl. cxiii, figs. 11 a, b. Flint, 1899, Rep U.S. Nat. Mus. (1897), p. 316, pl. lxiii, fig. 3. This handsome species is fairly well represented in our series by some broad but otherwise typical specimens. C. latifrous was originally recorded by Brady from the “Challenger” station at Culebra Island, West Indies, 390 fathoms, and off the west coast of New Zealand, 275 fathoms. To these localities Flint adds Florida, and Gulf of Mexico, 60 to 210 fathoms. Cristellaria articulata, Reuss sp. Robulina articulata, Reuss, 1863, Sitzungsb. d. k. Ak. Wiss Wien, vol. xlviii, p. 53, pl. v, fig. 62. Cristellaria articulata Reuss sp. Brady, 1884, Rep. Chall., vol. ix, p. 547, pl. lxix, figs. 1–4, 10–12. Flint, 1899, Rep. U.S. Nat. Mus. (1897), p. 317, pl. lxiv, fig. 2. It is of much interest to add another locality for this somewhat restricted species. The previous records are Culebra Island, West Indies, 390 fathoms, and off Nightingale Island, Tristan d'Acunha, 100–150 fathoms (Brady); also Gulf of Mexico and off the Coast of Georgia, 169 to 276 fathoms (Flint). C. articulata is characteristic and fairly common in our sounding off Great Barrier Island. No examples of wild-growing forms such as Dr. Brady describes were met with in the present series. Cristellaria rotulata, Lamarck sp. Lenticulites rotulata,Lamarck, 1804, Ann. Mus., vol. v,p. 188, No. 3; and 1806, vol. viii, pl. lxii, fig. 11. Cristellara rotulata, Lam. sp., Flint, 1899, Rep. U.S. Nat. Mus. (1897), p. 314, pl. lxiv, fig. 4. Millett, 1903, Journ. R. Micr. Soc., p. 257. This widely distributed species has already been recorded by the “Challenger” from station No. 169, off the east coast of New Zealand. It is not uncommon in our sounding off Great Barrier Island. Cristellaria orbicularis, d'Orbigny sp. Robulinu orbicularis, d'Orbigny, 1826, Ann. Sci. Nat., vol. vii, p. 288, pl. xv, figs. 8, 9. Cristellaria orbicularis, d'Orb. sp., Chapman, 1895, Proc. Zool. Soc. Lond., p. 33. Flint, 1899, Rep. U.S. Nat. Mus. (1897), p. 317, pl. lxiv, fig. 3.

A single specimen was found in our material. This species has been recorded off Sombrero Island, West Indies; and from the South Pacific—amongst other localities mentioned by Dr. Brady—off the west coast of New Zealand, 150 fathoms; off Sydney, 401 fathoms; and off Moncœur Island, Bass Strait, 38 fathoms. Dr. Flint found this species in the Gulf of Mexico at 210 and 169 fathoms. Cristellaria cultrata, Montfort sp. Robulus cultrata, Montfort, 1808, Conchyl. Syst., vol. i, p. 214, 54e genre. Cristellaria cultrata, Montf. sp., Flint, 1899, Rep. U.S. Nat. Mus. (1897), p. 318, pl. lxv, fig. 2. This species is common and widely distributed. It is somewhat abundant in our material. Brady remarks of this species that it affects deeper water than the non-carinate C. rotulaia, and that fine specimens are rarely met with at less than 100 fathoms. C. cultrata has been recorded by the “Challenger” from station No. 169, off the east coast of New Zealand. Cristellaria mamilligera, Karrer. Cristellaria mamilligera, Karrer, 1864, “Novara,” Exped., geol. Theil, vol. 1, Palæont., abth. ii, p. 76, pl. xvi, fig. 5. Brady, 1884, Rep. Chall., vol. ix, p. 553, pl lxx, figs. 17, 18. The previous records of this species as a recent form are by Brady—off Kandavu, Fiji, 210 fathoms, and off the Philippines, 92 fathoms. One well-grown shell occurs in our material from Great Barrier Island. C. mamilligera was found as a fossil by Dr. Karrer in the Tertiary greensandstone of New Zealand (Orakei Bay), and by C. von Gümbel in the nummulitic marl of the Bavarian Alps.

Soc., p. 258 This is a rare form in recent deposits, the “Challenger” having only recorded it from three stations—at the Canaries, off Kandavu, Fiji, and off Raine Island, Torres Strait. C. costata has also been reported from the shores of the Adriatic, and Millett observed it in soundings from the Malay Archipelago. Two specimens were found off Great Barrier Island.

This species has a wide distribution, but is best developed in the Southern Hemisphere. The localities given by Brady are in the North Atlantic, the North Pacific, and the South Pacific (off the west coast of New Zealand at 145 and 275 fathoms, and near the Fiji Islands, and south of New Guinea). Egger has recorded this form from Western Australia, and Millett has lately found it in the Malay Archipelago. The specimens from our sounding off Great Barrier Island are both numerous and large.

Egger, 1893, Abhandl. k. bayer. Ak. Wiss., cl. ii, vol. xviii, abth ii, p. 399, pl. xvi, figs. 7–9. This elegant little species is apparently almost confined to the Southern Hemisphere. It has already been found off the shores of New Zealand, and is a well-known Australian species. Our specimens have the keel strongly accentuated, and the chambers showing a nodulous appearance on the inferior surface as in Brady's figure 2. Not common in our sample.

(Zool.), vol. xxviii, p. 194. Millett, 1904, Journ. R. Micr. Soc., p. 491. T. reticulata has been previously found in the South Pacific, but it does not seem to have been recorded from the neighbourhood of the present locality. It is very rare in our series.

The above species is represented in the present series by a fair number of specimens. It does not appear to have been recorded from the vicinity of Great Barrier Island. Brady regards this form as of essentially deep-water habit. In the South Pacific its range in depth is from 210 to 1940 fathoms, so that it is rather surprising to meet with so many typical specimens in our sounding at 110 fathoms.

Besides the typical specimens there are some which seem to link, by their depressed superior face, the above species with a form like T. præcincta, Karrer, or T. dutemplei, d'Orb. sp. It is somewhat singular, considering its abundance, that this species has not bitherto been recorded from the locality. Truncatulina (?) præcincta, Karrer sp.

Although there seems to be reason for supposing that d'Orbigny's two works, to which reference is made above, were published almost simultaneously, yet the actual dates of publication differ, and therefore, according to the rule of priority, the better-known specific name, P. micheliniana, unfortunately must lapse. This species has been already recorded for the South Pacific, and notably at sta. No. 169. It is not uncommon in our series. Pulvinulina crassa, d'Orbigny sp. Rotalina crassa, d'Orbigny, 1840, Mém.

Brady records this species as abundant in the South Pacific. It was also found by Millett in the Malay Archipelago. Egger obtained it from soundings taken by the “Gazelle” off Mauritius and New Guinea. Rare in our series. Report on the Ostracoda. All the species of Ostracoda here recorded, with the exceptions of Asterone australis, Brady, and Cytherideis hedleyr, sp. nov., have been previously described in the report on the dredgings made by the “Challenger,”* Reports “Challenger” Expedition, Zoology, pt. iii, 1880: Ostracoda, G. S. Brady. and the former species in a later publication by the same author.†† Trans. R. Soc. Edin., 1890, vol xxxv, pt. ii (No. 14). The “Challenger” station nearest ours which yielded Ostracoda is No. 167, west of New Zealand, and from this three species only in common with our series are recorded. Among other localities which afford species in common with those of our list are: Off Booby Island. near Cape York, north-east Australia (“Challenger” sta. 187), and Cocos Island, Indian Ocean (coll., C. W. Andrews). Twelve species of Ostracoda of known forms occur in our dredging, but only four of these occur in each of the localities above mentioned; and, curiously, both of these dredging were taken in quite shallow water. The species which occur both in our list and that from Booby Island are Cythere tetrica C crispata C cancellata, and Xestoleberis margaritea Those from Cocos Island common to our list are C cancellata C prava C dictyon, and Xestoleberis margaritea. The following is a list of the Ostracoda found in the present material, and the species new to the list given in the “Index Faunæ Novæ-Zealandiæ” are marked with an asterisk Of the fourteen species of Ostracoda given below, nine are new to the New Zealand area.

The “Challenger” dredgings yielding this species were from Port Jackson, 2 to 10 fathoms; Booby Island, 6 to 8 fathoms; and from anchormud at 7 fathoms in Hong Kong Harbour. A right valve of this species was found in our dredging; it is not so sharply sculptured as in typical specimens, and at first sight would suggest affinity with C canaliculata, Reuss. Our specimen differs from the last-named, however, in having the anterior extremity of the carapace, in edge view, decidedly wedge-shaped.

Cythere tetrica, G. S. Brady. Cythere tetrica, G. S. Brady, 1880, Rep. Chall., Zool., pt. iii, p. 104, pl. xxiii, 5 a-d. This somewhat striking form has been previously recorded only from Booby Island, Torres Strait, 6 to 8 fathoms. One right valve found in our series. Cythere dictyon, G. S. Brady. Cythere dictyon, G. S. Brady, 1880, Rep. Chall., Zool., pt. iii, p. 99, pl. xxiv, 1 a-y. Five separate valves of this widely distributed species were found, one of which appears to belong to a full-grown female, and shows the posterior spines arranged along the border of the shell. Another example is a small valve of the same sex, whilst the remainder are valves of male specimens. Cythere prava, Baird sp. Cythereis prava, Baird, 1850, Proc. Zool.

It appears to be more at home in shallow water. Our specimen is a right valve, the surface of which is more than usually coarsely sculptured. Cythere dasyderma, G. S. Brady. Cythere dasyderma, G. S. Brady, 1880, Rep. Chall., Zool., pt. iii, p. 105, pl. xvii, 4 a-f; pl. xviii, 4 a-f. In the “Challenger” dredgings this species was characterized as a deep-water form, so that its occurrence in the present sounding is somewhat exceptional. It is also widely distributed. One right valve. Genus Krithe, Brady, Crosskey and Robertson. Krithe producta, G. S. Brady. Krithe producta, G. S. Brady 1880, Rep. Chall., Zool., pt. iii, p. 114, pl. xxvii, a-j.

The deepest sounding from which Dr. Brady obtained his specimens was taken at 1,675 fathoms. The writer records

this species from the “Penguin” soundings round Funafuti at 1,489. 1,995, and 2,715 fathoms He also obtained this species from soundings in the Arabian Sea. near the Laccadive Islands (s.s. “Investigator”). Not uncommon, but rather small, in the dredging off Great Barrier Island. Genus Xestoleberis, G. O. Sars. Xestoleberis margaritea, G S. Brady sp. Cytheridea margaritea, G. S. Brady, Trans. Zool.

Dr. Brady found this species in the “Challenger” dredgings at one locality only—namely, off Booby Island, Torres Strait, 6–8 fathoms. The same author also records it from the Mediterranean and the Mauritius. The writer found it in the shallow-water sands of the outer beach and lagoon of Funafuti, where it was fairly common, and in the lagoon sands of Cocos Island. One perfect carapace found off Great Barrier Island. Xestoleberis africana, G. S. Brady. Xestoleberis africana, G. S. Brady, 1880, Rep. Chall., Zool., pt. iii, p. 126, pl, xxx, 4 a-c. This is a very rare and restricted form It was originally recorded from Simon's Bay, South Africa, 15 to 20 fathoms. One left valve found in our dredging from Great Barrier Island. Genus Cytherideis, Jones. Cytherideis hedleyi, sp. nov. Plate III, 8 a-c. Description—Carapace elongated, compressed. Seen from the side, arcuate and siliquose; depressed in front; greatest height about the middle; posterior extremity slightly produced at the ventral angle; back evenly arched, ventral edge sinuous. Edge view elongate-ovate, rounded at the back, compressed in front; greatest thickness about the middle of the lower third. Surface of carapace ornamented with closely set polygonal areolæ or pittings, arranged in more or less regular concentric lines. A linear series of muscle-spots situated in a lateral depression of the carapace just below the median area. Length, 0 6mm.; height, 0·225mm.; greatest thickness of carapace, about 0·66mm.

Affinities.—In outline our species is somewhat comparable with C foveolata, G. S. Brady,* Ann. Mag. Nat. Hist., ser. 4, vol. vi, 1870, p. 454, pl. xix, 1–3. with the exception that the valves of that species are not produced in the postero-ventral region; it further essentially differs from ours in the surface-markings of the carapace, which in C foveolata consist of a minute and dense punctation. Another form of the same genus which we may compare with the present species is C ondrewsi, Chapman,† Proc. Zool, Soc. Lond., 1902, p. 229, text 27. which, however, shows the following differences: Test less depressed at the anterior end; ornament not so distinctly polygonally areolate, and muscle-spots arranged in rosette form. Very rare in our sounding. Section Myodocopa. Family Cypridinidæ. Genus Cypridina, Milne-Edwards. Cypridina (?) danæ, G. S. Brady. Cypridina danœ, G. S. Brady, 1880, Rep. Chall., Zool. pt. iii, p. 156, pl. xxxvi, 2 a-d. The specimen before us is somewhat crushed, making an exact comparison difficult. It resembles the above species fairly closely in side view. but the relative proportions of the carapace in edge view are not clearly seen. Our specimen, like that of Brady's, is partially chitinous in places, and the anterior notch and posterior truncated beak are similarly shaped as in C danœ. Brady's species is based on a single specimen obtained from Kerguelen Island at a depth of 120 fathoms. Genus Asterope, Philippi. Asterope australis, G. S. Brady. Asterope australis, G. S. Brady, 1890, Trans. R. Soc. Edin., vol. xxxv, pt. ii, p. 515, pl. iv, 1, 2. Idem, 1898, Trans. Zool. Soc., vol. xiv, p. 431, pl. xliii, 1–8. It is of great interest to meet with this genus in the present collection, since the cypridinads are comparatively rare in the Southern Hemisphere, so far as they are at present known. Brady's original specimens of A australis came from the coral islands of the Pacific—Nouméa, 2–4 fathoms; Suva, inside reef; Mango Island, fringing-reef; Apia, Upolu, reef and shore pools. One typical carapace was found in the present sounding off Great Barrier Island.
