 Empidochanes altirostris, Cab. J. f. 0. 1868, p. 196 (Cartagena) ? 



Above brown, with an olivaceous tinge ; a slightly lighter loral 

 spot ; wings blackish, with the tips of the coverts and outer edges 

 of the external secondaries pale rufous or ochraceous ; tail ashy 

 brown : beneath pale ashy white, lighter on the throat, and with a 

 strong yellowish tinge on the belly ; upper mandible dark brown, 

 lower whitish ; feet pale brown : whole length 4-7 inches, wing 2-5, 

 tail 2-3. 



Hub. Guiana, Venezuela, and Amazonia. 



This is a Northern form of E. bimaculatus, distinguished by its 

 slightly smaller size, less rufescent tinge above, and more yellowish 

 colour beneath. It is, perhaps, doubtful whether it is really entitled 

 to the name oliva (based upon PI. Enl. 57-4. fig. 2), but that name 

 has traditionally descended to one of this group of birds, and may 

 be assigned with more probability to this species than to any other. 

 I do not like to use the name altirostris of Cabanis for it without 

 being able to examine the type.
