CHARACINIDAE FROM VENEZUELA—SCHULTZ 283 
U.S.N.M. No. 121405, 2 specimens, 26.5 and 27.5 mm. in standard length, 
collected by L. P. Schultz, G. Zuloaga, William Phelps, Jr., and Roger Sherman, 
May 12, 1942, in the Rio Gudrico and tributaries between San Sebastidn and San 
Casimiro, Estado de Aragua. 
It is highly probable that the above specimens and others from the 
Orinoco system, here identified as this species, are really a distinct 
subspecies. They usually have ii, 9 pectoral rays instead of i, 8, as 
counted in two of Liitken’s specimens and Reinhardt’s count.
