young of the different species, as from the great similarity 

 existing In many, it is highly probable that the species have 

 been unnecessarily multiplied. 



S. Macropus. Kanguroo. Front teeth in the upper jaw 

 (of the adult animal) six ; in the lower two, very large, 

 long, sharp and pointing forwards ; grinders five on 

 each side of both jaws, distant from the other teeth ; 

 fore-legs \eTy short, hind ones exceedingly long; tail 

 long : the female possesses an abdominal pouch. 



The Kanguroo has only been met with in New Holland, 

 were it is used for the purpose of food, and the skin for 

 various articles of dress and domestic uses ; its progress is 

 not by running or walking, but by prodigious leaps, fre- 

 quently to the extent of thirty feet at a single bound, and 

 these are so rapidly repeated as to enable it to escape from 

 the fleetest greyhounds. It feeds on grain and vegetables. 



9. Talpa. Mole. Front teeth in the upper jaw six, un- 



equal, in the the lower eight; tusks solitary, the 

 upper ones largest ; grinders in the upper seven, in 

 the lower six. 



This class reside principally beneath the surface of the 

 earth, they feed on worms, insects, roots and seeds; they 

 are exceedingly prolific aud are very injurious to the farmer 

 and agriculturist, most abounding in campaign countries. 



10. Sorex. Shrew. Upper front teeth two, long, bifid; 

 lower two or four, the intermediate ones shorter ; tusks 

 many on each side ; grinders cuspidate.
