PHIMOSUS INFUSCATUS BERLEPSCHI Hellmayr: Berlepsch’s [bis

(Orinoco region). 
SPECIMEN COLLECTED 
1 ad. o, Venezuela, Puerto Ayacucho, Rfo Orinoco, January 4, 1930. 
Hellmayr circulated proof sheets containing this species and marked 
them ‘“‘Verhandl. Zool.-Bot. Ges. Wien, Heft 3-4—22.5.03,” the present 
name appearing on p. “‘xvi” of the proof. If this be considered as 
constituting valid publication the reference given above should be 
altered accordingly. I am indebted to the late Dr. C. W. Richmond’s 
invaluable card file of bird names for this nformation. 
Unfortunately, there are no notes on the color of the bare parts of 
the head accompanying our specimen, which is thus, of necessity, 
identified to subspecies on geographic grounds. The race berlepschi 
is said to have the bare part of the head dark carmine, the bill wood 
brown with a blackish tip, but the carmine, like the corresponding 
clay color of the Brazilian race P. 1. nudifrons, fades out to yellowish 
in dried skins.

The bird is in a molting stage; the remiges are only partly grown 
and are still enclosed in their sheaths basally. 
This tree duck occurs in suitable places throughout the Amazonian- 
Orinocoan regions traversed by the collectors. It is wholly a bird of 
the tropical lowlands, seldom occurring over 1,000 feet above the sea.
