the river from Ciudad Bolivar and Caicara beyond the falls of Alai- 
pures as far as I extended my explorations.

The three species of Crotophaga seem to be found throughout the 
Orinoco region. Of .the two smaller forms C. ani is the more abun- 
dant. I did not observe sulcirostris above the falls, but Miller collected 
a specimen for the American Museum at Maipures.

Native name Hervidor Oriquelo. Not observed below Ciudad 
Bolivar, but noted at almost all points visited beyond. This species 
frequents the tangled thickets and densely wooded areas that cover 
or border swamps, ponds or water courses. Like other members of 
the genus they are social, going about in small flocks of from six or 
eight to twentv or thirtv.
