104 MAMMALIA. 



do the Dog for hunting. That of Java, L. leptonyx, Horsf. 

 (The Javanese Otter) has a whiter throat, and this whiteness 

 ascends on the sides of the head so as to surround the eye. In 

 that of the Cape, L. capensis, Fr. Cuv. the white on the throat, 

 sides of the head and neck is purer and more extended j the end 

 of the nose is even marked with it : what particularly distin- 

 guishes it, however, is that, at least at a certain age, it has no 

 nails, a character on which M. Lesson has founded his genus 

 AoNYX. Young individuals however have been brought from 

 the Cape that have nails ; it remains to be ascertained whether 

 or not they are of the same species. 



Mustela Intra brasiliensis, Gm. (The American Otter.) 

 Brown or fawn-coloured j throat white or yellowish ; a little 

 larger than the European Otter ; the body is also longer, and 

 the hair shorter. It is distinguished by the end of the nose, 

 which is not naked as in most animals, but is covered with 

 hair like the rest of the chanfrin. From the rivers of both 

 Americas. 



Mustela Jutris, L.j Schreb. CXXVIIL(l) (The Sea-Otter.) 

 Size, double that of the European species ; body much elon- 

 gated J tail one-third the length of the bodyj the hind feet very 

 short. There is sometimes white about the head. It has only 

 four incisors below, but the molars are like those of the other 

 Otters. Its blackish velvet looking fur is extremely valuable, 

 to obtain which the English and Russians hunt the animal 

 throughout the northern parts of the Pacific ocean. 



In the second subdivision of the Digitigrada there are two 

 flat tuberculous teeth, behind the superior carnivorus tooth, 

 which is itself furnished with a large heel. They are car- 

 nivorous, but do not exhibit a courage proportioned to their 

 powers, and frequently feed on carrion. The csecum is al- 

 ways small. 



Canis, Lin. 



Dogs have three false molars above, four below, and two tuber- 

 culous teeth behind each of the carnivori ; the first of these upper 

 tuberculous teeth is very large. Their superior carnivorus has 

 only a small inner tubercle, but the posterior portion of the inferior 



(1) This figure, apparently drawn from a badly prepared specimen, presents an 

 exaggerated resemblance to the Seal, a cb-cumstance by which some naturalists 

 have been induced to believe it should be placed near that genus its whole or- 

 ganization, however, is that of the Otter. See Ev. Home, Phil. Trans. 1796.
