Art. XXX.—Revised List of New Zealand Seaweeds: Part II.* For Part I., see Trans. N.Z. Inst., vol. xxxii., art xiv. By Robert M. Laing, B.Sc. [Read before the Philosophical Institute of Canterbury, 6th November, 1901] Here, as in the previous part of this paper, no attempt is made to give a complete synonymy of the species. Only such references are given as will introduce the student to the chief literature of the subject, where he will find full descriptions, and also fuller lists of synonyms, which will enable him to pursue his investigations. I have to express my thanks to Major Reinbold for his kindness in identifying a number of specimens. Sub-class Florideæ. Order Ceramiaceæ. 96. Rhodocorton parkeri, Harvey Gibson, Journ. of Bot., 1893, p. 161. Brighton, Otago: Professor Parker. This plant was apparently found epiphytic on Lychæte darwinii (vide Laing, Trans. N.Z. Inst., vol. xxvii., p. 300). 97. Rhodocorton (Callithamnion) rothii. Fl. Nov.-Zel., p. 260. Hawke's Bay and Cape Kidnappers: Colenso. This plant has not been collected lately, but might be overlooked on account of its smallness.

98. Antithamnion ptilota, Harvey Gibson, Journ. of Bot., 1893, p. 161 (Callithamnion ptilota, Hook. and Harv., Lond. Journ. Bot, iv., p. 272). New Zealand: Professor Parker. 99. Antithamnion (Callithamnion) adnatum, J. Ag., De Alg. N.Z. mar., p. 12. Bay of Islands, on Gelidum corneum: Berggren. Lyall Bay: R. M. L. Specimens found by Major Reinbold amongst seaweeds sent Home by myself from Lyall's Bay seem to belong to this species. It is, however, by no means a well-known plant. 100. Antithamnion (? Callithamnion) applicitum. Fl. Nov.-Zel., p. 258. Parasitical on Amphiroa: Colenso. A little-known and not recently collected species. 101. Antithamnion (Callithamnion) plumula. Fl. Nov.-Zel., p. 258. D'Urville Island: Lyall. Var. investiens. St. Clair: J. C. S. (Conf. J. Ag.). 102. Callithamnion flaccidum. Fl. Nov.-Zel., p. 258. Otago: Lyall. I have some plants from the west head, Wellington, which come close to this; but in the absence of type specimens it is practically impossible to identify them with certainty. 103. Callithamnion puniceum. Fl. Nov.-Zel., p. 259. Tauranga: Davies. I know nothing about this plant. It appears among Agardh's “Species inquirendæ.” 104. Callithamnion consanguineum. Fl. Nov.-Zel., p. 260. Port Nicholson: Lyall. Bluff: J. C. S. I know nothing about this plant. This plant also appears among Agardh's “Species inquirendæ.” 105. Callithamnion byssoideum. Fl. Nov.-Zel., p. 260. Bluff and Otago: Lyall. Maketu: Chapman. 106. Callithamnion brachygonum. Fl. Nov.-Zel., p. 259. Blind Bay: Lyall. Tauranga: Davies. Dunedin Wharf: J. G. S. and R. M. L. Warrington: Berggren. Wellington Harbour: R. M. L. 107. Callithamnion hirtum. Fl. Nov.-Zel., p. 258. Port Cooper, Otago, Port Underwood, Port William, Tory Channel: Lyall. This is probably the commonest of our species of Callithamnion. It is everywhere plentiful in the South Island.

108. Callithamnion colensoi. Fl. Nov.-Zel., p. 259. East Coast and Hawke's Bay: Colenso. 109. Callithamnion mucronatum, J. Ag., Sp., p. 29. Dunedin: R. M. L.; J. C. S. 110. Callithamnion(?) confusum, Harv. J. Ag., Epicr., p. 250. (Wrangelia squarrulosa: Fl. Nov.-Zel., p. 236.) New Zealand: Lyall. 111. (??) Warrenia comosa, Harv. (Callithamnion comosum, J. Ag, Epicr., p. 19.) The Nuggets, Wyckliffe Bay, St. Clair: R. M. L. St. Clair: J. C. S. A beautiful plant; the identification due to Agardh, but to me it seems very doubtful. 112. Pleonosporium brounianum, Harv. (Harvey Gibson, Journ. of Bot., 1893, p. 161.) Brighton (?): Professor Parker. 113. Ballia callitricha. Fl. Nov.-Zel., p. 257. (Vide “On the Minute Structure of Ballia callitricha,” Archer, Lin. Soc. Trans., Dec., 1876.) Chatham Islands: Dr. Schauinsland. Bluff, Dunedin, Warrington, Banks Peninsula: Berggren. Common, along the east coast of the South Island; Lyall Bay: R. M. L. Dredged in 8 fathoms at Akaroa: H. Suter! 114. Ballia scoparia, Harv. (Callithamnion scoparum: Fl. Nov.-Zel., p. 259.) Common along the east coast of the South Island. 115. Griffithsia sonderiana, J. Ag., Epicr. Flor., p. 62. This is probably the common species of Griffithsia, but the New Zealand forms are not sufficiently known. 116. Griffithsia antarctica. Fl. Nov.-Zel., p. 258. East Coast: Colenso. Ruapuke, Foveaux Strait, and East Coast: Lyall. I have not yet been able to recognise this species with certainty among my specimens. 117. Pandorea traversii, J. Ag., in Enum. Alg. Chatham. Chatham Islands: Travers. Lyall Bay: Berggren. Paterson's Inlet; also abundant for some months in Sumner, at Taylor's Mistake, and on the coast near Wellington: R. M. L. 118. Ptilota pellucida. Fl. Nov.-Zel., p. 257. Otago: Lyall. Dunedin, Warrington, Banks Peninsula: Berggren. The Nuggets, Lyall Bay: R. M. L. St. Clair: J. C. S. Mr. Smith informs me that this plant was by no means uncommon in the neighbourhood of St. Clair some four or five

years ago, but that it seems to have disappeared completely since then. My Wellington specimens (1901) are epiphytic on P. formosissima. 119. Ptitota formosissima. Fl. Nov.-Zel., p. 257. Probably everywhere abundant. Bluff, Dunedin, Warrington(?), Banks Peninsula, Lyall Bay: Berggren. Kai-koura: R. M. L. Chatham Islands: Dr. Schauinsland. Brighton (Otago): J. C. S. 120. Ceramium virgatum, Harv., Fl. Nov.-Zel., p. 256. East Coast: Colenso. Taylor's Mistake: R. M. L. Chatham Islands (identification doubtful): Dr. Schauinsland. (Vide also Anal. Algol., cont. ii., p. 44.) 121. Ceramium diaphanum. Fl. Nov.-Zel., p. 256. Port Cooper, Akaroa, and Otago: Lyall. Petone: R. M. L. St. Clair (common): J. C. S. 122. Ceramium nodiferum, J. Ag., Epicr., p. 99. Chatham Islands: Travers. New Zealand: (Agardh). (Vide also Anal. Algol., cont. ii., p. 40.) 123. Ceratmium stichidiosum, J. Ag., Epicr., p. 105. (Anal. Algol., cont. ii., p. 21.) Cape Kidnappers: A. Hamilton! Chatham Islands: Dr. Schauinsland. Var., Lower Green Island beach: R. M. L. 124. Ceramium vestitum. Fl. Nov.-Zel., p. 256. (J. Ag., Anal. Algol., cont. ii., p. 40). Port Adventure: Lyall. Dunedin, Banks Peninsula: Berggren. This is a little-known and somewhat doubtful species. 125. (?) Ceramium pusillum var. lanceolatum, Harv., in Syn. Phyc. Austr., No. 619. (J. Ag., Alg. N.Z. mar., p. 14; also Anal. Algol., cont. ii., p. 21.) Tauranga: Berggren. 126. Ceramium uncinatum. Fl. Nov.-Zel., p. 257. (J. Ag., Anal. Algol., cont. ii., p. 36.) Turnagain: Colenso. Lyttelton, Lyall Bay, Whangaroa: R. M. L. This is a very distinct species, and probably common all along the coast. The tetraspores do not seem to have been previously described. They are of the usual type, and are arranged in a single verticillate series round the nodes. Originally totally immersed, when mature they emerge almost completely vertically, and are surrounded by a conspicuous hyaline membrane. It therefore belongs to the tribe Isogoma rather than to Zygogoma, in which Agardh provisionally placed it. The arrangement of the spines has been also imperfectly described by Harvey and Agardh. There are gene-

rally five at each node, a large one on the anterior side of the ramulus, two smaller ones on the posterior side. The remaining two are still smaller, and are intermediate in position on either side between the large one and the two smaller ones. They are difficult to distinguish until the specimen has been decolourized. 127. Ceramium apiculatum, J. Ag., Epicr., p. 105. (C. cancellatum: Fl. Nov.-Zel., p. 265.) (Vide also Anal. Algol., cont ii., p. 20.) On various parts of the coast (common): Lyall; Colenso; Davies; Chapman. Lyall Bay and Tauranga: Berggren. 128 Ceramium rubrum. Fl. Nov.-Zel., p. 256. Brighton (Otago), Lyttelton(?): R. M. L. Bluff, Owaka Beach, Green Island, St. Clair: J. C. S. According to Harvey many varieties of this plant are abundant throughout the Islands. It does not seem to me that this is the case, and so I give a list of the localities at which I have obtained apparently authentic specimens of it. Further examination will probably show that the name has been used as a cover for several species. 129. Ceramium divergens, J. Ag., Anal. Algol., cont. ii., p. 27. New Zealand: (Agardh. No locality given). 130. Ceramium nobile, J. Ag., Anal Algol., cont. ii., p. 41. Brighton (Otago): R. M. L. St. Clair: J. C. S. 131. Ceramium gracillimum, Harv., Phyc. Brit., tab. 206. (J. Ag., Epicr., p. 95; also Anal. Algol., cont. ii., p. 43.) Major Reinbold has kindly identified this plant for me from specimens forwarded to him and collected by myself at Lyall's Bay and in the neighbourhood of Wellington (Petone). The species is perhaps the same as C. byssoideum (Harv., Ner. Bor. Amer., ii, p. 218). 132. Ceramium miniatum(?), (Suhr) J. Ag., Epicr., p. 105. To this species Agardh somewhat doubtfully refers specimens collected by myself and Mr. Crosby Smith in Otago Harbour. 133. Microcladia pinnata, J. Ag., Anal. Algol., cont. iv., p. 34. Brighton (Otago): J. C. S.; R. M. L. 134. Microcladia novæ-zelandiæ, J. Ag., Anal. Algol., cont. iv., p. 35. This is almost certainly M. coulteri of Professor Harvey Gibson (Journ. of Bot., 1893, p. 161). It is very common from Lyttelton southwards, and it is strange that it has not been noted by any of the earlier collectors. This species

varies a good deal, and perhaps runs into the preceding; but there also appears to be a third form yet unnamed. The two species were named by Professor Agardh from specimens sent Home by Mr. Crosby Smith and myself. But in the interchange of letters some mistake has arisen about the labels, and I am now unable to lay my hands on type specimens of M. pinnata. 135. Centroceras clavulatum. Fl. Nov.-Zel., p. 277. Common on the coast and in river-estuaries: R. M. L. Order Cryptonemiaceæ. 136. Schizymenia stipitata, J. Ag., Epicr., p. 121. Banks Peninsula (very sparingly): Berggren. 137. Schizymenia novæ-zelandiæ, J. Ag., Epicr., p. 677 (also Anal. Algol., cont v., p 76). Bay of Islands: Berggren. 138. Nemastoma intestinalis.- Fl. Nov.-Zel., p. 255. Preservation Harbour: Lyall. Chatham Islands: Dr. Schauinsland. 139. Nemastoma laciniata, J. Ag., Epicr., p. 128. (Vide Note, Anal. Algol., cont. v., p. 76.) Dunedin and Banks Peninsula (very sparingly): Berggren. I have a specimen (from Lyall Bay, I think), but I have unfortunately lost the name of the locality. 140. Pachymenia lusoria, J. Ag., Epicr., p. 145. (Iridea lusoria: Fl. Nov.-Zel., p. 252.) Apparently abundant from Mongonui to Stewart Island. I may have occasionally mistaken some other plant for it, for its identification is often impossible without a very close examination; but it appears to be one of the commonest of our red seaweeds on exposed tidal rocks. 141. Pachymenia dichotoma, J Ag., Epicr., p. 146. Bluff: Berggren, R. M. L. 142. Pachymenia himantophora, J. Ag., Epicr., p. 680. Bay of Islands: Berggren. Stewart Island: R. M. L. Identification somewhat doubtful. 143. Pachymenia laciniata, J. Ag., Epicr., p. 145. Bluff, Dunedin (sparingly): Berggren. 144. æodes nitodissima, J. Ag., Epicr., p. 630. Bay of Islands: Berggren. Mongonui: R. M. L. There is a specimen in the Canterbury Museum, from Tauranga. 145. Grateloupia prolifera, J. Ag., Epicr., p. 150. (? Nemastoma prolifera, Harv., in Fl. Nov.-Zel, ii., p. 255.) Chatham Islands: Travers. Lower Green Island beach, Wyckliffe Bay, and Lyttelton: R. M. L.

Tauranga and Lyall Bay: Berggren. Gore Bay, Wellington Harbour, Lyttelton: R. M. L. 148. Grateloupia filicina, J. Ag., Epicr., p. 153. Chatham Islands: Dr. Schauinsland. 149. Cryptonemia latissima, J. Ag., Epicr., p. 682. Bay of Islands: Berggren. Order Gigartinaceæ. I have a large number of species belonging to this order, but so far have been able to identify a few of them only. It presents unusual difficulties. 150. Rhodoglossum latissimum, J. Ag., Epicr., p. 187. (Also Bldr. Alg. Syst., iii., p. 27; (?)Halymenia latissima, Harv., Fl. Ant.) New Zealand: Berggren. Lyall Bay: Reinbold (amongst specimens sent Home by myself). 151.

The identification of my Lyttelton specimens is due to Agardh, but is somewhat doubtful. 157. Gigartina polyglotta, J. Ag., Bidr. Alg. Syst., part iv., p. 29. Western coast of New Zealand: (Agardh). 158. Gigartina alveata. Fl. Nov.-Zel., p. 547. (J. Ag., Anal. Algol., cont. v., p. 20.) New Zealand: Banks; Cunningham; Hooker. Bay of Islands: Berggren. 159. Gigartina angulata, J. Ag., Epicr., p. 197. (Vide, also Anal. Algol., cont. v., p. 20.) (? G. stiriata, Harv., Fl. Nov.-Zel.) Chatham Islands, Bluff: Berggren. Brighton (Otago), Double Corner (Amberley), Lyall Bay: R. M. L. Probably common in the South Island at least: R. M. L. Professor Harvey Gibson also describes G. stiriata as from New Zealand (Journ. of Bot., June, 1893). I have seen one of his specimens, and am satisfied that it is G. angulata, J. Ag. The true G. stiriata is a native of Cape Colony. 160. Gigartina chapmanni. Fl. Nov.-Zel., p. 291, pl. 119. (J. Ag., Epicr., p. 190.) Tauranga, Bay of Islands: Berggren(?). Petone (Wellington Harbour): R. M. L. 161. Gigartina macrocarpa, J. Ag., Epicr., p. 683. (G. pistillata: Fl. Nov.-Zel., ii., p. 252, partim.) Bay of Islands: Berggren. The old species G. pistillata has been split up into several by Agardh. It was said to be common on the New Zealand coast. It will probably be found that the common form is G. divaricata. 162. Gigartina disticha, J. Ag., Epicr., p. 194. (Anal. Algol., cont. v., p. 10.) Dunedin: Berggren. 163. Gigartina marginifera, J. Ag., Epicr., pp. 196, 683. Dunedin, Warrington, Banks Peninsula: Berggren 164. Gigartina decipiens. Fl. Nov.-Zel., p. 547. (J. Ag., Epicr., p. 195; also Anal. Algol., cont. v., p. 20.) Dunedin, Banks Peninsula: Berggren. Akatore, Lower Green Island, Double Corner (Amberley), Lyall Bay: R. M. L. As most of my specimens are barren, it is possible that an allied species may sometimes have been mistaken for G. decipiens. 165. Gigartina insidiosa, J. Ag., Anal. Algol., cont. v., p. 22. This plant is apparently from New Zealand, though no definite locality is given for it.

166. Gigartina ancistroclada, Montagne. J. Ag., Epicr., p. 198. Akaroa: D'Urville Otago: Lyall. 167. Gigartina burmanni, J.

I have specimens of one or all of the last three species, but at present am quite unable to distinguish them satisfactorily, so I give no localities. 176. Gigartina longifolia, J. Ag., Anal.

Probably the most abundant species of the genus, but Agardh's description is by no means satisfactory. Apparently common on the east coast of the South Island, but perhaps confused with other species. 187. Callophyllis coccinea. Fl. Nov.-Zel., p. 250. Tauranga: Davies. Var. a cornea, J. Ag., Bidr.

Lyall Bay, Tauranga: Berggren. 203. Chylocladia(?) cæspitosa. Fl. Nov.-Zel., p. 253. Port Nicholson: Lyall. A very doubtful species. Champia. I have been considerably puzzled by the New Zealand species of this genus. Agardh (De Alg. mar. Nov.-Zel., p. 18) recognises only one, while in the “Flora Novæ-Zealandiæ” (p. 235) Harvey recognises three. Amongst my own specimens, which are fairly numerous, I have three forms; of these two perhaps which coincide with Harvey's Champia novæ-zelandiæ and C. parvula respectively, and the third is possibly distinct from any of Harvey's species. The only species admitted by Agardh is Champia novæ-zelandiæ, and it seems to me that this species properly defined should include both Champia novæ-zelandiæ, of Harvey, and C. parvula, of Harvey, for the following reasons: Agardh's specimens of Champia novæ-zelandiæ came from the Chatham Islands, and are apparently incomplete. He rightly distinguishes the juvenile from the mature form, but wrongly describes the whole frond as articulate. In the lower portions of the branches the articulations frequently quite disappear in the mature specimens. In the young frond, too, the stems inosculate, forming a dense tufted mass. In this form Raoul, who first identified the New Zealand form with C. parvula, probably mistook it for the European species, which it then resembles. I have a form from the Bay of Islands which Agardh thought might be a new species. It is but little branched; the branches are broader than in Champta novæ-zelandiæ, and the branchlets, particularly those bearing tetraspores, are more or less swollen and submoniliform. The branchlets, too, are rarely whorled, as in the Champia novæ - zelandiæ, but generally opposite. It may perhaps stand at present as a variety (tumescens) of Champia, novæ-zelandiæ.

Epymenia obtusa is stated by Agardh (loc. cit.) to be confined to South Africa. He further emphasizes as one of the chief differences between E. obtusa and E. wilsonis that in E. wilsonis each fertile leaflet bears only one cystocarp, and in E. obtusa numerous ones. I find on specimens of what I take to be E. wilsonis, from Lyall Bay, that there are several—sometimes four or five—cystocarps on each leaflet, and these sessile when young, though provided with a very short pedicel when old. Evidently we have not as yet got a good definition of our common species of Epymenia. 214. Epymenia acuta, J. Ag., Epicr., p. 334. Anal. Algol., p. 93. Harv., Fl. Nov.-Zel., p. 249. Akaroa: Lyatt.

I am completely puzzled as to this plant from lack of fruiting specimens, and also from lack of literature. On sending a plant Home to Professor Agardh, he returned it as probably Callophyllis tenera, but as it was sterile he was not certain as to the accuracy of his determination. On sending from Lyall Bay what I believed to be the same species as the preceding to Major Reinbold, he determined it as Craspedo-carpus erosus (Harv.) Schmitz = Rhodophyllis erosa (Harv.) J.

Nitophyllum(??) microphyllum, Crosby Smith (Mscr.). On the back of a Haliotis shell, Green Island beach: J. C. S. Mr. Crosby Smith has furnished me with the following description of this plant, which seems to be a new and distinct species, belonging perhaps to a new genus. In all particulars except one it belongs to Agardh's tribe Monantheæ, sub-genus Aglæphyllum, genus Nitophyllum; but, though in its vegetative structure its place is exactly here, its cruciately divided tetraspores would seem to throw it outside the genus Nitophyllum altogether. I have, however, retained it here for the present, marking the genus with two queries. The discovery and examination of the cystocarps may help to determine its position more exactly. I have deposited specimens in the Canterbury Museum.

Sub-genus Aglæphyllum, J. Ag., Sp. Alg., vol. iii., part iii., p. 38. Tribe Monantheæ, J. Ag., loc. cit., p. 46: “Nitophyllum microphyllum, Crosby Smith (Mscr.). Root an irregularly creeping rhizome. Fronds clustered, many from the same base, ecostate, stipitate, linear clavate, obtuse, 3–15 mm. long, distantly toothed or proliferously pinnate. The principal frond is often abruptly terminated, and from its apex springs a secondary leaflet similar to the primary one, and proliferous from the margin. Sori solitary in the terminal expanded lobes, and girt round by a sterile margin, the fertile portion expanding into an ovate, obovate, rotundate, or very irregular lamina. The tetraspores are cruciately divided, thus apparently distinguishing the plant from all others of the order. Colour when fresh bright-red, and on drying much darker. Substance membranous. This seaweed was found on a Haliotis shell on the Green Island beach. It completely covered the shell in a moss-like fashion. I have given it the specific name Microphyllum, as it is, so far as my knowledge serves, the smallest of the genus.” From the above description and classification it will be seen that the plant probably comes nearest to the Australian N. monanthos, J. Ag. (Sp. Alg., p. 655), from which, however, it differs in many ways—in the smaller size, the almost entire margin, the shape of the fronds, and, above all, in the cruciately divided tetraspores. 263.

I ventured (loc. cit.) to identify a species of Delesseria with D. crassinervia. Agardh (Sp. Alg., vol. iii., part iii., p. 217) animadverts on my criticism of his treatment of the species D. crassinervia, and states that he is altogether doubtful as to the identity of my plant. He suggests again that D. crassinervia, Mont., may be Nitophyllum endiviæfolium. Whether my plant is identical with that of Montagne may perhaps be left an open question in the absence of his type specimens, but it seems to me to agree better with his description than any other species which I know does. Agardh (Epicr., p. 496) points out that D. crassinervia, Hook. and Harv., is in part D. epiglossum, J. Ag., and again refers to this in Sp. Alg., vol. iii., part iii., p. 218; but my plant is certainly quite distinct from D. epiglossum. Further, I have a specimen of N. endiviæfolium sent me from Victoria by Mr. H. T. Tisdall, and this is certainly also distinct from D. crassinervia. It is possible my species may be Apoglossum montagneanum, J. Ag., of which I have seen no specimen; but, judging from the published descriptions, it differs considerably also from this. Since describing it previously I have observed the cystocarps but not examined them microscopically; they are solitary, and placed on the veins of the leaflets. It must be admitted that my photographs as they appear in the “Transactions of the New Zealand Institute” (vol. xxix.) perhaps justify Agardh's criticism of them. 277. Caloglossa leprieurii, J.

Identification due to Major Reinbold. Other species of Laurencia are to be found in New Zealand, but they are as yet insufficiently well known. Harvey gives Laurencia pinnatifida as. occurring in the Auckland Islands, and I have badly preserved specimens from Cook Strait and Dunedin Heads which may possibly belong to this species. 299A.

The species of this order are perhaps less well known than those of most of the preceding orders Some of the genera (e.g., Polysiphonia, Rhodomela) present unusual difficulties, though even where the species are well defined but little work seems to have been done upon them.

Chondriopsis. Our New Zealand species are common, but as yet very imperfectly described. I have many specimens of this genus, including at least three species; but none of the species represented agree altogether satisfactorily with any of Harvey's descriptions, yet two at least of them are very common. (For the limits of the genus, vide J. Ag., Bidr. Alg. Syst., iv., p. 89.) 308. Chondriopsis (Chondria) flagellaris. Fl. Nov. - Zel., p. 222. Port Nicholson, Paterson's Harbour: Lyall. 309.

Foveaux Strait: Lyall. Otago: Lindsay. Warrington, Dunedin, Banks Peninsula: Berggren. Chatham Islands: Dr. Schauinsland. Lyttelton, Pigeon Bay, Double Corner (Amberley): R. M. L. I have some specimens from Brighton (Otago) which may belong to this species, but more probably to a new and undescribed one. 310. Chondriopsis capensis(?). Harv., Ner. Austr., p. 86. (J. Ag., Anal. Algol., p. 149.) Some specimens collected by Mr. Crosby Smith at St. Clair are considered by Agardh to come nearer to this than to any other described species. 311. Bostrychia mixta. Fl. Nov.-Zel., p. 225. (J. Ag., Anal. Algol., cont. iv., p. 69.) Bay of Islands: Hooker. Otago: Lyall. Invercargill Jetty, Cape Saunders (identification uncertain): J. C. S. It may be doubted whether our plant comes within the stricter limits of the species described by Agardh (loc. cit.). 312. Bostrychia laingii, J. Ag., Anal. Algol., loc. cit., p. 72. Otago Harbour: J. C. S. In a footnote to this species Agardh refers to a B. disticha as occurring on the New Zealand coasts; of this I know nothing. 313. Bostrychia novæ-zelandiæ, J. Ag., loc. cit., p. 75.

Probably common along the East Coast of the South Island: R. M. L. 317. Bostrychia rivularis (?), Harv. J. Ag., Anal. Algol., cont. iv., p. 75. I found a species of Bostrychia growing abundantly immediately underneath the waterfall in Long Bay, near Akaroa Heads. On forwarding some of it to Agardh, he considered it was perhaps the same as the American B. rivularis, but see footnote on B. simpluscula (J. Ag., loc. cit., p. 73). 318. Rhodomela cæspitosa. Fl. Nov.-Zel., p. 225. Parimahu, &c.: Colenso. Bluff: Berggren. 319. Rhodomela gaimardi. Fl. Nov.-Zel., p. 225. Hawke's Bay: Colenso. Blind Bay, Akaroa: Lyall. 320. Rhodomela traversiana, J. Ag., De Alg. N.Z. mar., p. 28. Chatham Islands: Travers. Bluff: Berggren. New River Heads, Brighton (Otago), Lower Green Island beach, Moeraki: R. M. L. It is but right to say that, on forwarding some of my specimens to Agardh, he identified them merely as belonging to the genus Rhodomela, but refused to give them a specific name, as they were rather imperfect; but there is certainly abundant in Otago a species of Rhodomela which agrees well with Agardh's description of R. traversiana. The same plant is found from the Bluff to Moeraki, and if not R. traversiana is an undescribed species. Polysiphonia. Our New Zealand list for this genus is still very far from completion, and I have many plants of the genus which I am quite unable to name. Some of these are probably new. The following list can only be regarded as tentative. I have left out a considerable number of species unknown to Agardh or regarded by him as doubtful, though previously described from New Zealand. One or two of these are British, and probably represent wrongly identified New Zealand forms; of the others none have been recently collected, and may be left in abeyance until found again and redetermined. Here, as elsewhere, I have not introduced any fresh species to the list on my own authority alone, nor have I attempted to classify the species under any of the sub-genera; the references given will enable the investigator to do so for himself.

The species of the order Sphacelariacece are being revised in the “Journal de Botanique” by Professor Sauvageau (August, 1900, et seq.). Already several New Zealand forms have been dealt with. De Toni's “Sylloge Algarum,” unfortunately, is not procurable in the colonies, but would be of considerable assistance to the student. I cannot close this paper without referring to the death, at a ripe old age, of the greatest of algologists, Professor J. G. Agardh I found him always ready and willing to assist me, and I regret that he was unable himself to draw up this list, when it would have been of much greater value than it is.
