PachyrhamphMs niger Berlepsch & Hartert, p. 56 (Ciudad Bolivar, 
Altagracia, Caicara, Perico and Maipures Ri\er, Orinoco ; Suapure 
and La Pricion, Caura River. Venezuela). 
Not uncommon in the low thick underbrush bordering heavy timber 
on one hand and open savanna on the other. Found all along the river 
from the delta region at Las B.arrancas at least as far as San Fernando 
de Atabopo above the falls. 
The food consists apparently of about equal parts of insects and 
small fruits. 
In the male the eye is seal brown; bill plumbeous black at tip; feet 
slate grey; female, eye seal brown; bill above black, mandible whitish at 
base, slate grey at the tip; feet slate grey. 
Considerable individual variation, exist'^ in the amount of gre\ish 
mottling on the under surface, two out of four adult males having 
narrow ill-defined greyish shaft streaks on the chin and throat. A speci- 
men from Trinidad has the general under surface lighter grey, but 
with less distinct mottling. A specimen from Cayenne is nearly uni- 
form sooty black with very faintly indicated greyish mottling on the 
belly. The amount of grey on the rump is also extremely variable, in 
some examples scarce a trace being visible, the rump being nearly 
uniform black like the back.
