IS. ENHYDKIS. 119 



Pusa, Aken. 



Latax, Gloyer (not Grai/). 



Professor Lichtenstein's figure of the animal, in the Darst. Siiugeth. 

 t. 49, represents the hind feet as too small and too much like those 

 of a common Otter. The hind foot is like a compressed fin, quite 

 as much, and even more so than in the case of the Seal. It diJffers 

 from the foot of the Seal in the toes gradually increasing in length 

 from the inner to the outer one, making the foot appear obHquely 

 truncated. In the Seals, the inner and outer toes are the longest, 

 and the middle ones are the shortest. In some respects the foot of 

 the Sea-Otter resembles that of the Beaver ; but it differs in the toes, 

 as well as in being entirely covered, both above and below, with short, 

 close, silky hairs. The front cla^s are small, short, and very acute. 

 In the very yomig animal they are very acute and strongly curved 

 at the tip, so as to be almost subspiral. The hinder claws are small 

 and acute, rudimentary in the very young specimens. The muffle 

 is bald : it forms a bald edge round the nostrils, which are only 

 separated from each other by a rather narrow septum ; and it forms 

 a rather triangular bald space over them, the upper edge being 

 sloping on each side, and rather arched in the centre. The figures 

 in Capt. Cook's ' Voyages,' t. 57, give the best idea of tlus animal, 

 showing the fin-like form of the hind feet ; but the tail appears too 

 depressed and Beaver-like.
