There is also presented on each side an outstanding process 

 which is found on some of the vertebrae of some members of 

 the genus. They occupy a position about the middle of the 

 height of the vertebral centrum and near the hinder end.

The type of this species is here figured (Fig. 37). The 

 original description given by Professor Cope seems to be 

 sufficiently clear and accurate. Dr. Loomis has figured a 

 mandible and premaxilla of what appears to be this species. 

 His specimen is different from that described by Cope in 

 having the band of teeth wholly on the inside of the dentary, 

 instead of having it about equally distributed on the inside 

 and the outside of the bone. Fig. 37 shows how much of the

band of teeth was on the inside of the jaw in the type of the 

 species; the detached part of the figure represents the teeth 

 on the outer side of the jaw. It is possible that the differ- 

 ence in the two specimens is due to the crushing of one or 

 the other; but of which, it is now impossible to say.
