SPECIES. 201 



In 1874, the same author* added two more " new species" of 

 Otaria , this time wholly from old material, from unknown locali- 

 ties, which he had had before him in the British Museum for nearly 

 twenty years, and which he had hitherto uniformly referred to 

 Otaria jubata ! Having, however, found that the lower jaws 

 differed from those of the other specimens in being " straight, 

 not bowed on the side, and elongate," and that " the scar of the 

 temporal muscle is elongate, narrow in front," instead of being 

 " broad, rounded in front." One of the species, based on the 

 " skull of an adult male 11 J inches long, and 6J wide at the v 

 condyles," etc., he calls "Otaria minor, the Smaller Sea Lion." j. 

 The other, based on " the skull of an adult (female) 9 J inches long, I 

 and 5J broad at the condyles," he calls u Otaria pygmcea, the 

 Pigmy Sea Lion." The last-mentioned skull is " partly broken 

 behind, and wants all the grinders and the greater part of the 

 cutting teeth." They are unquestionably referable to the re- 

 stricted genus Otaria, and there is nothing in the descriptions 

 indicating that Dr. Gray's reference of them for twenty years 

 to 0. jubata was erroneous. The skull of Otaria minor is later 

 figured in the "Hand-List of Seals" (pi. xvi), and is evidently 

 that of a young male Otaria jubata. 



In this year (1874) also appeared the lastt of Gray's long 

 series of publications relating to the Eared Seals, in which we 

 have his latest views respecting the species of this group. In 

 this work two other " new species " are added, making in all 

 eighteen species of Otariidw now recognized by Dr. Gray! 

 These are: 1. Otaria jubata. 2. Otaria minor (see above, last 

 paragraph). 3. Otaria ulloce (=0. ullow, von Tschudi and 

 Peters, and 0. pygmwa, Gray, both formerly, and, I believe, cor- 

 rectly, referred by him to 0. jubata). 4. Gypsophoca tropicalis 

 { = Arctoeephalus cinerem). 5. Phocarctos hookeri. 6. Phocarc- 

 tos elongatus ( Eumetopias stelleri, in part, and Otaria stelteri, 

 Temminck, in part). 7. Callorhinus ursmus. 8. Arctoeephalus 

 antarcticus. 9. Euotaria cinerea (includes Arctoeephalus forste'ri 

 of Gray's Suppl. Cat. Seals and Whales [see above, p. 199]). 

 10. Euotaria nigrescens ( = Arctoeephalus australis). 11. Uuota- 

 ria latirostris (n. sp., based on a skull supposed to have come 

 from the Falkland Islands, formerly referred to his A. nigres- 

 cens. He now says, " The skull may belong to the Aretocepha- 

 lus falklandicus, of which [i. <?., his A.falJdandicus] the skull is
