The names used in this index are those used 

 by Cope, and a few of the species were erroneously 

 identified or names were perhaps transposed, but 

 no attempt has been made to bring the names up 

 to date or to correct errors. In some instances 

 Cope omitted the terminal lobes of the hemipenis, 

 particularly when they were long, slender ex- 

 tensions of the much broader basal part. The 

 plate on which the hemipenis appears is given 

 immediately after the name, followed by the 

 figure number in parentheses. 



The index is trimmed to fit into the back 

 of Cope 1 s book.
