Art. LVII.—On the Genus Rhynchonella. By Alex. McKay. [Read before the Wellingtou Philosophical Society 10th October, 1880.] It is by the permission of the Director of the Geological Survey that I have the pleasure of placing this paper before the Society. Of the mollusca Rhynchonella, although it is represented by but two living species, is, if the fossil species be taken into consideration, numerically the most important genus belonging to the Brachiopoda. In Woodward's “Manual of the Mollusca,” the genus is said to include 332 fossil species; some 60 species obtained in New Zealand have to be added, thus bringing the total to something like 400 species. At the present time R. nigricans alone survives in the southern seas, and is found on the New Zealand coast. This species is the only one found in our upper and middle tertiary strata. In the upper Eocene rocks of New Zealand, represented by the Mount Brown and Hutchinson quarry beds, another form appears, but this with its close ally R. nigricans is the only species yet known from our tertiary strata. From our upper secondary rocks two more species are added to the list, Rhynchonella Squamosa, Hutton, and a species not yet described, which is found in cretaceous rocks of the East Coast of Auckland.
