the same locality ; and further, Mr. Ramsay was so good as to give 

 me a skin and skull (figs. 3-5) of an animal of about the same age, 

 which had been taken at the same time and place as those exhibited 1 . 

 On the evidence of the skulls, I feel no hesitation in assigning these 

 two specimens to the same species as nos. 1 and 2 of the former group. 

 The skin, however, is much lighter in colour. On the head and back 

 the. dark-brown hairs are tipped with yellow, and a good many yellow 



Fie. 2. 



Otaria cinerea, <$ ; under surface of hinder half of skull to show the form of 

 the opening of the palate and of the auditory bulla ; half natural size ; 

 from the same specimen as fig. ]. 



hairs are mixed with the others ; the underside of the body is of a 

 light brown ; and a sparse underfur of the same colour lies at the 

 roots of the hairs on the back. The upper side of the 'pes' and 

 ' manus ' is covered with very short fine hair of a rich brown. 



We have, then, before us four specimens of an Otaria which has 

 been called Ar otocephalus cinereus ; and we have to investigate the 

 history of the species, and to determine whether they have been 

 rightly referred to it. 



In 1859, Dr. Gray, in one of his numerous revisions of the Seals, 



1 These specimens are in the Museum of the University of Cambridge. The 

 specimen purchased appears to be a male, not full-grown ; that given to me by 

 Mr. Eamsay is a female.
