    EUMETOPIAS—ARCTOCEl’HALUS. 178 The presence of a large species of Eared Hair Seal on the Auckland Islands was established by Mr J. W. Clark {P. Z. S., 1878), who identified it with the skulls collected by Sir J. C. Ross in his voyage to the Antarctic, which were named Arctocephalus hookeri by Dr Gray. The skull is distinguished by its great length in relation to both the zygomatic and cranial breadth. The hard palate is almost truncated, but ends behind about opposite the middle of the zygo- matic arch and well in front of the hamular pterygoids. No specimen in JMuseum. III. ARCTOCEPHALUS. (Arc.) Arctocephalus, F. Cuvier, Mem. du Museum, xi., 1824; and Diet. d. Sc. Mat., xxxix., 1827. Thick under-fur ; ears relativel}^ long; facial part of skull short, broad, with nares almost vertical in one species, in others elongated and pointed, with nares oblique; hard palate ends well in front of the hamular pterygoids, posterior border deeply concave; post-canines 6 6 5 5’ large central cusp, small anterior and posterior cusp not always present. External characters, skeletons, and skulls of several species of Fur Seals were described by Sir W. Turner in Challenger Reports, part Ixviii., 1887. (1) Arctocephalus ursinus. (Arc. ur.) (Fm- Seal of North Pacific, the Alaskan Fur Seal.) Ursus marinus, Steller, Nov. Comm. Acad. Petrop., ii., 1751. Phoca ursina, Linmeus, Syst. Nat., 1., 1758. Callorhinus ursinus. Gray, Proc Zool. Soc. London, 1859; and Allen, North American Pinnipeds, 1880. Anterior nares almost terminal, nearly vertical; front of face short, truncated, relatively broad; sliort nasals sloping downwards. These appearances are peculiar, and induced Dr Gray to make this species a new genus, Callorhinus, with which ]\lr Allen coincides. Teeth : molars — , small, one large cusp ; o o lower molars in addition a small anterior cusp, no diastema; 5tli upper molar in line with posterior
