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



leonina, but the palate is short and much contracted behind, the 



teeth more lobed, and with a tubercidar ridge below, Kke the 



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



Sir George Grey, K.C.B. 



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

 (Arctocephalv^ australis) found eighty mUes inland in South Australia, 

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

 (see Cat. Ost. CoU. Mus. CoU. Surg. p. 647. nos. 3964 & 3965). 



*** Hinder edge of the palate large, gradually contracting into an angle 



in front. 



3. Arctocephalus Califomianus. 

 Arctocephalus Monteriensis, junior ?, Ch-ay, P. Z. S. 1859, 367. 



The young animal is blackish, silvered by the short white tips 

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

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

 and more silvery. The under-fur is very abundant, reaching nearly, 

 to the end of the hair. The end of the nose and sides of the face 

 are whitish. The whiskers are elongate, rigid, smooth, and white. 

 The hind feet are elongate, with rather long flaps to the toes. 



Inhab. California. 



The skull is very small for the size of the skin, and I should have 

 doubted its belonging to the skin if it were not accompanied by the 

 following label : — 



a. " Skull of the Fur Seal I sent last year. It is very imperfect, from 

 my forgetting where I had put it ; but it must do until acci- 

 dent throws another in the way ; the other bones were lost. — 

 A. S. Taylor." Presented by J. H. Gumey, Esq., M.P. 



This is the skull of quite a young animal, with what I am induced 

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

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

 differs from the adult A. Monteriensis 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 opportunity of comparing it, that is
