QUADRUPEDS. 181 



grinders, the tuherculeuses of M. F. Cuvieu, do not ex- 

 ceed two in number, and occupy the back-part of the jaw. 

 Their summits are flatter than the chewing grinders, and 

 they are usually of a smaller size. The larger they are, the 

 less carnivorous the species to which they belong *. The 

 teats are ventral. 



Toes separate, and the feet suited for walking. Hind 

 legs f idly developed. 



PLANTIGRADA 



Walk on the soles of the feet. 



The toes are five in number r ; and the entire sole, 

 which is bare, rests on the ground. There is no coecum. 

 They feed chiefly during the night ; and many of them be= 

 come torpid in winter. 



1. Middle incisors produced ; lateral ones and tusks short. 



a. Two small incisors between the produced ones in the 

 lower jaw. No external ear:J^. 



Five fingers. 



33. Mygale. (Cuvier.) Snout produced and flexible. 

 The Musk Rat, or Desman of Lapland {Sorex moschatus), 

 Gm.) is the type. 



34. ScALOPs. (Cuvier ) Snout pointed. Sorex aqua- 

 ticus, Lin. 



• These descriptions will be better understood, by consulting Plate I. Fig ?., 

 where a delineation of the giinders of the badger is given, a is an inside 

 view of the teeth of the upper jaw. The tusk is followed by one small, and 

 two large tearing grinders. To these succeed one chewing grinder, followed 

 by a large bruiser. In the lower jaw b, the bruiser is small ; the chewer 

 large, and there. is an additional tearer. 



■f There are likewise five fingers, unless in the genus Chrysochloris. 



4: The toes arc webbed, enabling the species to swim. In this, character 

 .they approach the palmated division.
