The immature males have the three outer pairs of the rectrices 
tipped and externally barred with white. The two “immature” 
females are probably fully adult as they have adult rectrices. 
In his notes on this species Todd (Proc. Biol. Soc. Washington, 
vol. 56, 1943, p. 5) records that the width of the white pectoral band 
is geographically variable, being narrow and even obsolete in Bolivian 
examples, but wide and well developed in specimens from both the 
Lower and the Upper Amazon. The present series of Upper Ama- 
zonian birds have this band quite well developed but in sufficiently 
varying degrees as to make one cautious in using the character for 
further splitting of the species.

As Todd has pointed out (Proc. Biol. Soc. Washington, vol. 56, 1943, 
p. 12) females of this subspecies cannot be distinguished from those 
of typical violaceus, but the males are identifiable by having the upper 
wing coverts and secondaries with little or no light vermiculations. 
Two of the males listed above have these feathers solid black; the 
third has very faint whitish vermiculations, which are noticeable only 
on close examination. 
The limits of the range of ramonianus are still to be worked out. 
Thus, toward the east, Griscom and Greenway (Bull. Mus. Comp. 
Zool., vol. 88, 1941, p. 182) write that their specimens of 7’. v. erissalis 
from the Tapajéz, Rio Acard, and Benevides, all in lower Amazonia, 
“aoree with ramonianus, and differ from the violaceus-caligatus series, 
in having the blackish, very minutely freckled wing-coverts. They 
differ from true ramonianus ... in having smaller bills. This is
