Subspecific characters. — Similar to Pipromorpha oleaginea chlorojiota, but 

 averaging paler, more buflfy, less ochraceous below, with less olivaceous 

 shading on the throat and breast; upper parts also averaging paler. 



Measurements. — Male (six specimens) : wing, 59-66 (63); tail, 43-53 (48); 

 bill, 10-12 (11); tarsus, 15.5-16.5 (16). Female (six specimens): wing, 

 57-60 (59); tail, 43-47 (45); bill, 10-11 (10.5); tarsus, 14-15.5 (15). 



Range. — Northeastern Venezuela to the islands of Trinidad and Tobago. 



Remarks. — Birds from the type-locality of this race agree well with 

 Trinidad skins, as remarked by Mr. Hellmayr, who discriminated the form 

 in 1906. Typical specimens are easily separated from the Amazon Valley 

 birds (chloronota) by their generally paler, duller coloration, in which respect 

 they approach the form from northern Colombia (parca), being in fact 

 intermediate between the two. The only Tobago specimen we have exam- 

 ined does not seem to present any special peculiarities, and we therefore 

 follow Mr. Hellmayr in considering birds from that island the same as those 

 from Trinidad. We would accordingly restrict pallidiventris to the arid 

 coast region of northeastern Venezuela, extending thence to Trinidad and 

 Tobago.
