quite well but raise the maximal measurements slightly, the wing in 
two males being 49 and 50 mm., and in a female 52 mm., respectively, 
but their other measurements do not show any difference from the 
Venezuelan birds. The birds of British Guiana may prove separable 
on the basis of color, two adult males from that country being darker, 
more washed with dusky orange on the midventral area and more 
abundantly flecked with dusky olive on the sides than Venezuelan 
examples. An adult female from British Guiana has the upper 
abdomen, sides, flanks, and under tail coverts more heavily washed 
with dusky olive-green and has the dorsal greenish area somewhat 
more pronounced, more distinct from the slate blue of the head and 
nape. 
Hellmayr (Catalogue of the birds of the Americas, pt. 9, 1936, p. 
67, footnote) writes that “birds from the Rio Negro appear to agree 
with others from British Guiana.’”’ A male (by plumage, not sexed 
by collector) from Rio Negro agrees with Venezuelan ones in the 
ventral coloration. 
If one were to separate the British Guiana birds as a distinct sub- 
species the type locality of the species (and therefore of the nominate 
form) would have to be defiaitely restricted. The original type 
locality is generally considered to be erroneous as the species has not 
been rediscovered in Colombia. The next definite locality in litera- 
ture is Rio Negro (Sclater, Proc. Zool. Soc. London, 1856, p. 280), but 
in view of the intermediate character of the bird from there, it would 
seem better to take a place geographically more extreme. Of course, 
if it were possible, the type specimen should be critically examined 
before deciding this point.

The single example collected agrees with others from Upper Ama- 
zonian Brazil (Rio Negro).

lad. #, 1 ad. 9, Chapazon, Brazo Casiquiare, Venezuela, January 30, 1931. 
These specimens agree with a small series from British Guiana and 
“Bogota,’’ Colombia. The measurements of these birds are smaller 
than those given for the race by Hellmayr (Catalogue of the birds of 
the Americas, pt. 9, 1936, p. 83, footnote) but the birds agree better
