 GENUS STENORHYNCUS F. Cuv. 



Stenorhyncus, u e. Narrow-muzzled Seal. 



We now proceed to the second Genus proposed by M. F. 

 Cuvier, denominated Stenorhyncus, Narrow-muzzled Seal. " The 

 head of this Seal," he remarks, "is all snout, when compared 

 with the former genus ; the teeth, too, are quite peculiar. There 

 are four incisors in the upper jaw in place of six; and the molars, 

 though the same in number, are quite different in shape." 



Baron Cuvier has very happily expressed it in these words : 

 " There are four very pointed incisors in each jaw; the two mid- 

 dle ones above are smaller, and are inserted farther back in the 

 mouth than the others ; the molars are deeply divided into three 

 long points, which are conical, and somewhat hooked."
