Geothlypis melanops, BAIRD, 0. 8. 
Hab. Eastern Mexico. 
(No. 26,372, %.) Bill slender, conical; culmen nearly straight to the 
gently decurved tip. First quill about equal to the 7th. Tail considerably 
graduated ; the feathers broad. 
Color much as in G. trichas, with a similar black mask, crossing the fore- 
head and passing over the cheeks and ears, through the eyes. This black 
mask is, however, bordered internally and above for nearly its own width by 
white, very faintly tinged with bluish, the nape only in fact being tinged 
with olive brown. The rest of the upper parts are olive green. All the under 
parts are pure rich uniform yellow, even including the middle of belly, the 
edge and the inside of wings; the sides of body are somewhat tinged with 
brownish. Bill black; legs yellowish. 
Total length, 5.00; wing, 2.44; tail, 2.60; graduation, .41; width of outer 
feather, .33 ; difference of Ist and 4th quills, .24; length of bill from forehead, 
55, from nostril, .34; along gape, .65; tarsus, .84; middle toe and claw, .75; 
claw alone, .25; hind toe and claw, .56; claw alone, .27. 
In a series of over one hundred specimens of black-faced Geo- 
thlypis, agreeing in general characters with G. trichas, there is one 
specimen from Mexico so different from all the rest as apparently to 
be entitled to specific separation. It is of considerably larger size 
than the average of G. trichas; the tail is longer; its feathers 
broader. The feet are larger; the middle toe and claw much longer. 
The entire under parts are of a nearly uniform yellow, without the 
whitish of the abdomen so characteristic of typical G. trichas. The 
space above, and inclosed by the black facial mask, is quite pure 
bluish-white, of much greater extent than in other specimens. 
This species is probably resident in Mexico, as the specimen de-
