 In the Beema river. 



Gen. Pelecus. Agassiz. 



Body much compressed, elongated, belly cutting ; dorsal opposite 

 anal, which is longish; gape wide. 



McLelland has placed the fishes of this genus among his Opsarii, 

 but they are very distinct in general habit, structure, and mode of 

 coloration, and are I think worthy of forming a distinct genus, which 

 Agassiz assigns to them.

 curved ; lateral line very little bent, dorsal small, placed slightly in 

 front of anal; pectoral large ; ventral and caudal small — D. 9, A. 17 —
