The Venezuelan examples are very slightly smaller, and the females 
average slightly bluer, than the Brazilian specimens, but the differ- 
ences are very slight indeed. 
One of the January males from Sao Gabriel is molting into the black 
plumage. 
Although no material of P. c. hoffmansi Hellmayr has been avail- 
able for study, no variations toward the described characters of that 
form have been observed in the present series.

1 ad. o, 1 - [=ad. &], Brazil, Serro Imeri, near Salto do Hud, Brazil- 
Venezuela line, December 7, 1930. 
These two specimens are more strongly tinged with orange on the 
abdomen than are a series of five from British Guiana, but the 
difference may be due to the great difference in the age of the speci- 
mens and the fact that the Guiana birds are not in too good condition. 
However, on the colored plate accompanying the original description 
the abdomen is represented as decidedly orange. This plate is a 
little misleading in that it shows no bluish posterior edging to the 
white coronal patch. This blue edging is found in specimens from 
British Guiana as well as in the present two. Chapman (Bull. Amer. 
Mus. Nat. Hist., vol. 63, 1931, p. 105) and Gilliard (Bull. Amer. 
Mus. Nat. Hist., vol. 77, 1941, p. 485) found that examples from 
Mounts Roraima, Duida, and Auydn-tepui have richer orange under- 
parts than others from British Guiana, but their Guianan birds, like 
those seen in the present study, were old.
