The oldest of the three adult skulls in the British Museum differs 

 from the other two in the pterygoid processes of the hinder edge of 

 the palate being closer together than in the rest ; but this character 

 seems to depend on the greater age of the animal, as it differs slightly 

 in the other two specimens. In all the younger specimens, varying 

 greatly in size, the pterygoid processes are far apart. 



Dr. Peters considers (1) Platyrhynehus leoninus of F. Cuvier, (2) 

 Phoca Byronia of Blainville, and (3) an adult specimen which is in 

 the Hamburg Museum, and of which he described and figured the 

 skull as O. Godeffroyi, to be distinct species. I cannot see any 

 difference between the skull in the College of Surgeons, on which 

 Phoca Byronia was founded, and those in the British Museum ; and 

 the figure of the skull described as O. Godeffroyi is very similar to 

 the skull in the British-Museum collection which I have called 

 O. jubata. 



This animal has the harsh fur without any under-fur of Phoc- 

 arctos Ilooleri ; but it entirely differs from that animal in the colour 

 of the fur. This cannot arise from the greater age of the animal, as 

 it is not nearly so large as the half-grown P. Hoolceri in the British 

 Museum. 



In the dark blackish-brown colour of the fur and the pale-brown 

 colour of the nape, and in the absence of the under-fur, this Seal 

 resembles the adult Neophoca lobata from Australia ; but in that 

 species the pale colour extends all over the crown, while in the young 

 male Otaria jubata there are only a few paler scattered hairs on the 

 middle of the crown and nose. 



Dr. Murie represents the skull of a nearly full-grown male and of 

 a female nearly of the same age (P. Z. S. 1869, p. 103. f. 1, 2). 

 They greatly differ, the nose and the palate being much wider in 

 the male than in the female, and the teeth in the male (but this 

 may be only an individual peculiarity) were much worn down.
