on the Sea Lion? of the Coast of California,* with a profile figure of an 

 adult male skull of what he supposed to he a new species {Arctocepha- 

 lus monteriensis), hut which proved to he identical with the Otaria 

 Stefan of authors, as first suggested hy Dr. Gill. Another young skull 

 was described and doubtfully referred to the same species, as was also 

 the skin of a fur seal. The latter, however, is undoubtedly identical with 

 the Northern fur seal (CaUorhinus ursiuus). In this paper he gives a 

 new classification of the eared seals, in which he properly raised the first 

 of the sections of his genus Arctocephalus, which he had previously in- 

 stituted, to the rank of a genus {Callorhinus) . The second and third 

 sections he seems to have reunited, for which he retained the name of 

 Arctocephalus. His genus Arctocephalus, as now restricted, he again 

 divided into four unnamed .sections. A valuable table of comparative 

 measurements of the skulls of eight species is appended. 



Seven years from the date last given (1859) carries us to the ap- 

 pearance of Dr. Gray's " Catalogue of the Seals and Whales," f pub- 

 lished in 18GG, during which interval little or nothing of importance 

 was published relating to the group in question. In this Catalogue all 

 the species of his "Catalogue of Seals" of 1850 are retained; the 

 synonymy is brought up to date, and the species he and others had 

 described since the appearance of that Catalogue are added. These are 

 the Otaria GlUespii McBain (= Zalophus Gillespii Gill, the Arcfo- 

 cepkalus monteriensis Gray (= Eumetopias Stelleri Peters), and the 

 Arctocephalus Californianus Gray (= CaUorkinus ursiuus, in part or 

 wholly), making the whole number of species thirteen. Only one of 

 the three species supposed to he new, however, proved to be so. 



The specific nomenclature is not changed from that adopted in his 

 previous paper, so far as the species mentioned in that paper are con- 

 cerned, and the introduction of one generic name is the only change 

 from the generic nomenclature employed by him in 1850. Another 

 new classification of the species of the genus Arctocephalus is given, in 

 which the species are grouped in two primary sections and seven sub- 

 sections, upon the* arbitrary basis of the differences in the form of the 

 bony palate. No new material is described, and lint little new matter 

 added, the Catalogue being essentially a compilation from his previously
