I have examined the male of the first form of this species pre- 

 served in the Philadelphia Academy, from Mirador, Mexico 

 (already mentioned by Faxon). The copulatory organ belongs 

 to the type of the subgenus Procambarus and is allied to that of 

 C. williamsoni and flilosimanus. It differs in the very strongly 

 developed shoulder, and the position of the horny, procurved 

 spine, which is almost terminal on the inner part. The tips of 

 inner and outer part resemble those of C. williamsoni. 



An additional locality for this species is represented in the 

 collections of the Philadelphia Academy : 



Texolo, State of Vera Cruz, Mexico. — S. N. Rhoads coll. 

 1899. — 3 c? (II), 2 9. (Texolo is near Xico, on the branch 

 road from Jalapa, distant about 15 miles from Jalapa.) 



In the males of the second form of this set, the shoulder of 

 the sexual organs is not quite so sharp, and the inner part is 

 more pointed.
