E. scotti Gidley. — The type specimen of this species was 

 found in 1899 by J. W. Gidley (6.111) at the head of Rock 

 Creek ; the more mature specimen (Plate IX and iig. 2) found 

 by the Yale Expedition furnishes a few points of added interest. 

 The skeleton is that of a female five or six years of age and 

 as now mounted stands about fifteen hands high.
