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- 

 ing a series of blotches on the upper lateral line and a second larger 

 series on the middle of the side; vertical fins dark greyish with series of 

 blackish spots." (Regan.) 



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. 



Habitat: Pacific slope of Panama.
