Braziliau birds (from Bahia, etc.), as a rule, have the upper parts rather paler 

 and more brownish (less greyish and blackish), and perhaps could be distinguished 

 as F. g. nigricollis (Swains.).

The Cayenne specimens of this form collected by Mr. Cherrie differ from 

 F. consobrina Scl. from W. Ecuador, with which Mr. Sclater has associated his 

 Cayenne bird, by Laving much smaller rounded white spots on the tips of the 

 larger upper wing-coverts, these spots being not much larger than those on the 

 middle and smaller coverts, while in F. consobrina as well as in the allied i^. boucardi 

 and F. qtiixensis they are very much larger, forming a large white area on the 

 wing. This difference is to be seen in both sexes. Otherwise the Cayenne form 

 resembles F. consobrina Scl. of Colombia, and presents the same long white tips to 

 the outer tail-feathers, while F. boucartii has them very much shorter. 



As far us lean judge from a single iVmale of /^. consobrina from Chimbo, 

 W. Ecuatlor, in my collection, the Cayenue I'emales have the under-parts of a some- 

 what lighter rufous brown, and are more blackish, less greyish on the front.
