truncate or slightly rounded. Caudal peduncle about 4/s as long as deep. 
Reddish brown, each scale with a dark spot; 5 or 6 dark cross-bars form-

This species was not seen by us. The above description is an exact 
copy from Regan, Annals and Magazine of Natural History, Ser. 7, 
Vol. XVI, 1905, p. 235. 
If the type of this species actually came from Panama, it is rather 
singular that it was not obtained there by us. C. tuyrense is more 
closely related to this species than any other taken by us, but there are 
such important differences that it is scarcely possible that the two are 
confused.
