Am. Mus. No. 4550a, Cope Coll., Lower Permian, North Fork of Little Wichita 
River, Texas. Fig. 1, neck and anterior part of trunk; fig. 2, posterior part of 
trunk to anterior part of tail; fig. 3, middle portion of tail. The remaining 
figures are probably of this individual, but 1 am unable positively to identify 
them. The specimen has been much more thoroughly pieced together since it 
was acquired by the American Museum, being in fact a nearly complete articu- 
lated skeleton, lacking only the distal parts of limbs and feet. With it was 
associated a second skeleton, lacking the skull and jaws, but otherwise almost 
as complete as the other. Professor Cope appears to have considered both as 
portions of a single skeleton.
