The Cayenne bird agrees with specimens from Munduapo, on the Orinoco; 

 the under-parts are perhajis a little more rnfescent. The species is new to the 

 fauna of Cayenne.

The single specimen of this rare species collected by Mr. Gherrie agrees with 

 Pelzeln's type in the Vienna Museum, with which I have compared it. It only 

 differs in having the reddish brown of the throat a little paler (not so reddish) 

 and not extended over the upper breast. The abdomen is also a little paler, 

 more olivaceous, less brownish. The upper Iparts are somewhat darker, more 

 blackisb ; the njiper tail-coverts are of a somewhat darker chestnut. The rufous 

 brown of the under tail-coverts is more intense.
