256 CLASS MAMMALIA. 



sometimes only, like the legs, with divers tubercles. 

 These animals have large ears ; sometimes four, 

 sometimes five great nails before, but five always 

 behind. The muzzle is pointed ; the cheek-teeth cylin- 

 drical, separated from each other, seven or eight in 

 number, everywhere without enamel onthe interior 

 side ; the tongue is soft, but little extensible ; some 

 separate hairs between their scales, or on the parts of 

 the skin which are without scales. They dig bur- 

 rows, and live partly on vegetables, and partly on 

 insects and carcasses ; their stomach is simple, and 

 they are without caecum. They belong to the 

 warm, or at least the temperate, parts of America. 

 The species may be almost distinguished by the 

 number of their intermediate bands combined with 

 the form of the compartments ; the bands neverthe- 

 less are subject to vary one or two, according to 

 the individuals.

 mensions are moderate.
