 narrow, with a thick rounded edge in the hinder part of the lower

 web ; claws two or three, very small, rudimentary, horny, acute. 

 Hind feet large, broad, triangular, hairy above and below ; the outer

The fii'st and second grinders of the upper jaw are small, with a 

 single conical root ; on the right side both these teeth are united 

 together in one cavity ; and as there are four other grinders on each 

 side, it would appear as if there were front grinders of two sets. 

 The third, fourth, fifth, and sixth of the same jaw have a compressed, 

 single, tapering root, with a deep central groove nearly dividing it 

 into two parts, the groove being deepest and most distinguishable on 

 their outer side. In the lower jaw the front grinder has a double 

 crown, with a thick single root, tapering below, as if formed of two 

 teeth united together by their roots ; the second and third grinders 

 have a broad, compressed, single root, divided by a rather deep, 

 central, longitudinal groove on each side ; and the fourth and fifth 

 grinders each have two tapering, nearly parallel roots, well separated 

 at the base from each other. In this skull the palate is rounded 

 behind, and the suture between the two bones is much more nearly 

 in its centre. I do not recollect to have observed such a malforma- 

 tion, or soldering together of the roots of the teeth, in any other Seal.

The skull has the first upper and lower grinder with a single large 

 subcylindrical root, tapering to a point beneath, and each of the 

 other grinders has two conical separate roots diverging nearly from 

 the collar. The palate is broad and rather truncated behind, and
