one smaller, with a single large root, the 2nd, 3rd and 4th neatly 
equal, and the 5th smaller and more compressed; the 2nd and ~ 
3rd have the root only divided at the base, the 4th and 5th have — 
the roots divided nearly to the crown, and diverging; the first — 
under is smallest and single-rooted, the rest are all similar, 2- — 
rooted, the 3rd beimg the largest, and the 5th most compressed — 
m the crown; the symphysis of the lower jaw is very long. \ 
The teeth of the younger animals have a rather broader crown, — 
with rather shorter tubercles, a rugose surface with some smaller 
tubercles on the inner side, near the base of the hinder lobes, | 
but separated from them by a groove. 
Body tapering behind. The fore limbs moderate, rather elon- 
gate, triangular, hairy above and below: toes 5, tapering, with 
a narrow, “thick, hairy web between them ; claws d, elongate, — 
acute, subequal : the hind lmbs large, beans triangular, hairy 
above and below; the outer toes on each side of the foot very © 
large, broad, rounded at the end, the three middle ones smaller, © 
narrow, tapering, with a thick hairy web between them, the © 
central one smaller and shorter, all clawless: tail short, conical, — 
depressed. 
Fur close-set, rather rigid, directed backwards, soft at the end ; 
the hairs flat at the base, tapermg to a fine point, without any — 
under-fur at the roots. |

This genus is more nearly allied to Stenorhynchus than to — 
Phoca, to which the French surgeons have referred it, but still — 
it differs so much from that genus in the conformation of the ~ 
skull and the lobing and rooting of the teeth, that it can scarcely — 
be left in it: but the latter peculiarity appears to have escaped : 
Mr. Owen’s research, for in his generic character of Stenorhyn- % 
chus he says, ‘‘ Anterior molars with one root, the rest with two — 
roots,” while in this genus the three front upper molars are 
single-rooted, a character by which this genus differs from all 
the others in the family.
