jubata, and a skull from California (where it is called Lobo marino) 

 by Gray (P. Z. S. 1859, p. 357, t. Ixxii.) as Arctocephalus mon- 

 teriensis. 



I was induced, erroneously, to describe the skull of the very 

 young specimen that accompanied this as a species, under the name 

 of A. calif ornianus, not being aware of the change in the form of the 

 palate. 



Phoca SteUeri, Fischer, Synopsis, p. 231, was established on the 

 Leo marinus of Steller ; but this animal has been generally con- 

 founded with Phoca jubata by Gmelin and different authors. 



The Lion marin de Californie, figured by Choris, ' Voyage Pit- 

 toresque,' t. xi., is probably from this species, and has been named 

 Phoca and Otaria calif ornica. 



In Eumetopias the six upper cutting-teeth in the very young skull 

 occupy the same space as the four middle upper cutting-teeth in the 

 adult skull, and the outer ujiper cutting-teeth and the canines are 

 very much enlarged. 



In the foetal skull from California the hind upper grinder is 

 at a considerable distance from the others, as in the very old 

 skull in the Museum and the two adult skulls figured by Mr. 

 Allen ; but there is to be observed on each side a concavity in the 

 place of the fifth grinder — on the right side it is a shallow, 

 smaU. cavity, which has enclosed a rudimentary tooth ; on the other 

 side the concavity is larger, but not so evidently the cavity for a 

 tooth. 



Mr. Allen, in the Bull. Mus. Comp. Anat. and Zool. Harvard Col- 

 lege, U.S., vol. ii., in his account of the " Eared Seals in the North 

 Pacific," figures the skulls and scapula of a very old and middle- 

 aged male, showing the variation in the shape of the internal 

 nostril.
