CHARACINIDAE FROM VENEZUELA—SCHULTZ 261 
U.S.N.M. No. 121348, 10 examples, 145 to 185 mm., from the Rio San Juan 
near bridge, Motatan system, March 20. 
U.S.N.M. No. 121338, 2 examples, 116 and 230 mm., from Lago Tulé, about 
80 km. west of Maracaibo, March 1. 
U.S.N.M. No. 121337, a specimen, 237 mm., from the Rio Palmar near Totuma, 
about 100 km. southwest of Maracaibo, February 21. 
One specimen listed above, U.S.N.M. No. 121335, at 37 mm. in 
standard length, has a black lateral band, not extending on caudal fin. 
After comparing this species with specimens of Luciocharaz insculp- 
tus Steindachner (new genus and new species) from the Magdalena 
Basin, it was concluded that Myers (2bid., p. 94, 1942) was fully 
justified in considering Steindachner’s species as a synonym of C. 
hujeta Valenciennes.

Prochilodus reticulatus magdalenae Steindachner? 
6 The descriptions of the species of Prochilodus reported from the Orinoco system and from Caracas are 
not adequate. Since no specimens are available to me from those localities, the data used in this key have 
been taken from the descriptions. Further information is needed to clarify the species already named in 
the Orinoco Basin. 
1 Prochilodus reticulatus magdalenae Steindachner, Denkschr. Akad. Wiss. Wien, vol. 39, p. 78, pl. 12, 
fig. 1, la, 1878 (Rio Magdalena) (description on p. 51 of this species leaves off the name magdalenae, but the 
latter is used in the legend for the plate).
