There is a specimen of Pteroglossus in the Am. Museum collection, 

 from Sacupano, Orinoco Delta, that differs from examples from Cristo- 

 bal Colon (Paria Peninsula), in that the thighs and under tail-coverts 

 are largely dusky greenish without reddish wash, whereas in typical 

 roraimae those parts are lighter, more dusky sulphur yellowish with a 

 reddish wash.
