 acute claws, and a rudimentary inner toe reduced to 

 a mere knob ; the hind limbs proportionally longer, 

 with five toes, and similar but shorter claws; the 

 tail nearly as long as the body and head. On the 

 fore feet the lateral toes are nearly equal, and much 

 shorter than the middle toes, which are also equal.

 The intestine, from the pylorus to the ccecum, 

 measures three feet eleven inches, its average dia- 

 meter being 3j twelfths ; beyond the coecum one
