Genus LEPORINUS Agassiz 
Leporinus Agassiz, in Spix, Selecta genera et species piscium ... Brasiliam 
. , p. 65, 1829. (Type, Leporinus novemfasciatus Agassiz.) 
The following species of Leporinus have been recorded from Vene- 
zuela or the Orinoco system. Since I do not have specimens of these 
species from the Orinoco system, I cannot work out the relationships 
with any degree of certainty and no key is attempted.
