Color in alcohol pale brown, more or less uniform, lower sm'face 

 and sides with bright reflections. Back with obscure underlaid 

 mottlings. Iris dull yellowish. 



Length 5^ inches. 



Type, No. 13,421, A. N. S. P. Surinam or Dutch Guiana. Dr. 

 Charles Hering. 



Known to me only from a single poorly preserved example which 

 is closely related to C. argenteus. It differs, however, chiefly in having 

 12 scales in a vertical series between the origin of the rayed dorsal 

 and the lateral line, and in the variegated back. The profile of the 

 head is also less attenuated and the second anal spine reaches further 

 beyond base of caudal. 



(Named for Dr. Charles Hering, who collected fishes many years ago 

 at Surinam or Dutch Guiana.) 



Other species examined are C. pectinatus Poey from Surinam, C. con- 

 stantinus Jordan and Evermann from Rio Janeiro and Los Matheos 

 in Brazil, C. argenteus Regan from Surinam, C. cuvieri Bocourt from 

 eastern San Domingo, C. armatus GUI from western Mexico, C. 

 pedimacula Poey from Havana, and C. ensiferus Poey from eastern San 

 Domingo.
