(No. 34,238, 9.) Top of head, back, and scapulars steel blue, with a 
greenish gloss, more violet in some specimens. Forehead from the eyes (not 
strictly defined), nuchal bands and rump (but not tail coverts), dark chestnut 
brown ; chin, throat, sides of breast and crissum, especially near anus, lighter 
chestnut brown; the sides of body and inside of wings smoky brown, tinged 
with the color just mentioned ; median region of the body white. No blackish 
on the breast or on forehead. Wings and tail with their upper coverts lustrous 
brown. A dusky spot in the loral region. 
(No. 34,238, 9.) Total length, 5.00; wing, 4.20; tail, 2.10; perpendicular 
depth of fork, .15; difference between Ist and 9th quills, 2.00; length of bill 
from forehead, .36, from nostril, .21, along gape, .56, width, .45; tarsus, .47 ;- 
middle toe and claw, .65, claw alone, .19; hind toe and claw, .37, claw 
alone, .20. 
The feathers of the back have a white patch on each side the shaft, 
about the middle, causing white streaks when visible among the 
feathers. The forehead and rump are quite dark chestnut; the 
chin and throat, with crissum just behind anus, come next in shade, 
this color fading still more on jugulum and sides (the jugulum some- 
times darker than chin), and scarcely appreciable posteriorly on the 
side of the abdomen. The longer feathers of crissum are dark brown, 
with reddish-white edges, much paler than near the vent. The white 
of the belly is sometimes glossed faintly with chestnut, especially 
along the shafts of the feathers. The axillars and lining of wings, 
with tibia, are of a smoky gray, with a rufous tinge. The chestnut 
nape is natrow, and sometimes quite obsolete ; the color of the neck 
behind it is dull and lustreless. The dark chestnut of the rump 
extends round on the sides as well as above, continuous with the 
paler tinge of the anterior portion of the crissum. The inner web 
of the lateral tail feather is edged with whitish near the end. 
There is no black band along base of upper mandible, as in Jwnv- 
frons. The chestnut feathers of the front exhibit a tendency to 
dusky centres, except near the bill, a feature not noticed in other 
species. 
This bird is much smaller than the North American lunifrons, 
and differs in the rufous chestnut (not whitish) front, the absence 
of black patch on throat, much lighter rufous of the throat (paler
