 i. Skull of h, adult. Very rugose ; very like adult skull of Otaria 



leon'ma, but the palate is short and much contracted behind, the 



teeth more lobed, and with a tubercular ridge below, like the 



younger skulls. N.W. Australia. Presented by His Excellency

Professor Owen describes a mutilated skull and jaws of a Sea Bear 

 {ArctocephaJus austrcdis) found eighty miles inland in South Australia, 

 presented to the Museum of the College of Surgeons by Dr. Robson 

 (see Cat. Ost. Coll. Mus. Coll. Surg. p. 647. nos. 3964 & 3965). (Srrct,-

3. Arctocephalus Califomianus. 



Arctocephalus Mouterieusis, junior?, Gray, P. Z. S. 1859, 357. " 



The young animal is bjacki^h, silvered by the short white tips 

 to the short black hairs ; those on the nape and sides of the hinder 

 part of the body hanng longer white tips, making those parts whiter 

 and more silverj'. The under-fur is very abundant, reaching nearly f ^ 

 to the end of the hair. The end of the nose and sides of the face ^^^*^'h<^ 

 arc whitish. The whiskers are elongate, rigid, smooth, and white. "^^^i-Ce^^- 

 The hind feet are elongate, with rather long flaps to the toes. / ""'^y (X^^t^

The skull is v ^-ry small for the si^ejjf the s kin, and I should have

This is the skull of quite a young animal, -mth Mhat I am induced 

 to believe are its milk-teeth, and, like the young skulls of most of 

 the species of this genus, is very unlike the adult form. It also 

 differs from the adidt A. Jlonferiensin in the form of the hinder opening 

 of the palate, which is very large and gradually contracted to an 

 angle in front of the mouth. I am not aware that the form of this 

 part is changed by the age of the specimen. It is not so in the only 

 species with which I have the ojjportunity of comparing it, that is
