arc quite remarkable, for while the femur is smooth, the tibia is 

 furnished with several prominences of large size; in modern types, 

 the prominences, if they occur at all, are found only on the femur; 

 in this specimen there is a slight rounded prominence on the upper 

 surface at the very base of the tibia and another just beyond the 

 middle; opjiosite the latter, on the upper surface, is a deeply bifid 

 elevation, its hollow corresponding to the elevation on the upper 

 surfece; the basal half of the under surface is occupied by a very 

 broad prominence, abrupt at its edges, of nearly ecpial height through- 

 out, but slightly depressed in the middle. Length of the femur, .28 

 inches ; breadth of the same, .1 1 inches ; length of the tibia, . 26 inches; 

 breadth of the same, .015 inches.
