2G2 BIRDS OF BRITISH GUIANA. 



Falls Demerara River, Arawai River (McConnell collection) ; 

 Bartica, Kamakusa {WhitAij). 



Extralimital Range. Northern Brazil, Venezuela, East Ecuador, 

 North Peru. 



Ilahits. Schomburgk states (Reis. Guian. iii. p. 69G) that he more 

 often met with this species in the sand-hills on the Demerara 

 River in light woods and usually in small flocks. In flying it 

 utters a note exactly like the humming of a top after which 

 follows a sound like the cracking of a hazel-nut, finishing up with 

 a booming which appears to be peculiar to this species. 



The nest is similar to that of CJiiroxiphia pareola, and is usually 

 found in low bush, which led to the supjjosition tljat its food 

 consisted of insects rather than fruits. 



Genus NEOPIPO Scl. & Salv. 



Neopipo Sclater & Salvin, P. Z. S. 18G9, p. 438. Type N. cinnamomea 

 (Lawr.). 



The species on which this genus was l)ased is one of the smallest 

 of the family. The bill is slightly hooked on the ujiper mandible, 

 the width at the base being rather more than half the leno-th of the 

 exposed culmen. The wing is rounded, the second, third, and 

 fourth primaries longest and equal, the first about equal in length 

 to the fifth. The tail is slightly rounded at the tip and about 

 three-fourths the length of the wing. The tarsus is rather more 

 than one-third the length of the tail, and the hind toe and claw 

 are nearly equal in length to the middle toe and claw. Colo- 

 ration : male and female similar.
