VIREO. 355 
with a grayish tinge; the sides of breast and body, with axillars and base 
of crissum (more faintly), bright yellow; the inner wing coverts and rest of 
Vireo noveboracensis. 
crissum much paler, almost white. A broad yellow line from nostrils to, and 
continuous with a yellow ring round the eye, which is encircled exteriorly by 
olivaceous ; a dusky loral, but no post-ocular spot. Wings with two covert- 
bands and innermost secondaries externally broadly yellowish-white; rest 
of quills edged externally with olive, except the two outer and tips of other 
primaries, which are grayish. Rectrices edged externally with olive, except 
outermost, which is bordered by grayish. All the long quills bordered in- 
ternally by whitish. Bill blue-black, paler on the edges; legs dark plumbe- 
ous. Iris white. 
(No. 10,193, %.) Total length, 4.90; wing, 2.40; tail, 2.20; exposed por- 
tion of lst primary, .78, of 2d, 1.56, of longest, (4th and 5th) (measured from 
exposed base of Ist primary), 1.86; length of bill from forehead, .53, from 
nostril, .30, along gape, .62; tarsus, .70; middle toe and claw, .50, claw alone, 
16; hind toe and claw, .40, claw alone, .20. 
(No. 1,036, %.) Fresh specimen: Total length, 5.00; expanse of wings, 8.00; 
wing from carpal joint, 2.50. Prepared specimen: Total length, 4.75; wing, 
2.50; tail, 2.25; difference between 10th and longest quills, .45; exposed: 
portion of Ist primary, .86, of 2d, 1.56, of longest (measured from exposed 
base of Ist primary), 1.90; length of bill from forehead, .51, from nostril, 
.29, along gape, .62; tarsus, .76; middle toe and claw, .52, claw alone, .18; 
hind toe and claw, .46, claw alone, .25. 
Specimens vary slightly in a greater amount of ashy on the head, 
and less brillianey of the yellow of head and sides. Sometimes 
there is a decided ashy shade in the white of throat and jugulum, 
which again has a very faint tinge of yellowish. 
A young bird does not differ in markings from the adult. 
A specimen marked ‘‘ Colombia” is rather smaller than the aver- 
age, but otherwise similar. 
The measurements of the feet of No. 10,193, %, appear to be 
quite abnormal, and I add those of No. 1,036, $, as more accurately 
expressing the average in these respects.
