Brycon striatulus Kner.

Brycon striatulus Regan, Biol. Cent. Amer., 1908, 169 (Juan Vinas 

 and El Pozo del Rio Grande, Costa Rica) , 



I did not obtain any specimens of this species in Costa Rica. This 

 species differs from the preceding in having 70 to 75 scales in the lateral 

 series instead of 52 to 56, the number for the preceding species. In 

 general appearance the two species are alike ; neither of the two species 

 of Brycon listed here have yet been taken on the Pacific side of Costa 

 Rica.
