stouter, the yellow patch on the pileum broader and paler, all the secon- 
daries and most of the primaries with the inner webs largely white; less 
white on the abdomen. 
&@ ad. (No. 51,515, collection of U. S. National Museum, Mazatlan, 
Mexico, March, 1868; Ferdinand Bischoff). Forehead and fore part of 
crown pale yellow; rest of upper parts (including the exposed surfaces of 
the closed wings and tail), sides of head, including the lores and a narrow 
space above the eyes, chin, throat, jugulum, and neck all around, glossy 
violet, mixed with steel blue on the lower back, scapulars, and wing- 
coverts, and nearly or quite clear steel blue on the primaries, secondaries, 
and tail feathers ; under wing-coverts, crissum, and under tail-coverts white, 
just perceptibly tinged with yellowish; tibiz whitish; rest of under parts 
rich chrome yellow, the feathers of the abdomen with much concealed 
white; inner webs of the outer and next to outer pair of tail feathers 
white from the base to within about .o8 inch of the tip; third pair of 
feathers with a short white stripe confined to the margin of the inner 
web; all the other feathers wholly dark; first primary with a narrow 
white margin on the basal half of the inner web; second primary with 
this white margin occupying nearly half the inner web for two thirds its 
length; third primary with the white extending nearly to the shaft on the 
basal third of the feather, thence tapering to nothing on the margin just 
half an inch short of the tip; all the remaining primaries, as well as the 
secondaries (but not the tertials which are wholly dark colored), with the 
entire inner web white to the shaft for about two thirds of the distance 
from base to tip. Wing, 2.29; tail, 1.36; length of bill along culmen from 
base, .40; length of bill from feathers, .26; depth of bill at nostrils, .19; 
width of bill at rictus, .25 inch. Bill (in dried specimen) nearly white 
at base, shading towards the tip into dark horn color. 
Habitat. Coast region of western Mexico (Mazatlan and 
Alamos). 
In addition to the type, which belongs to the National Museum, 
I have before me another specimen, similar in every way (except- 
ing that the bill is wholly dark horn color save for a small light 
space near the ¢zf of the lower mandible), taken by Mr. Frazar 
at Alamos, Sonora, Mexico, March 16, 1888. This bird measures : 
wing, 2.21; tail, 1.44; length of culmen from concealed base, 
.35; length of culmen from feathers, .25 ; depth of bill at nostril, 
-19; width of bill at rictus, .25 inch. 
Although Mr. Ridgway considers this new species most closely 
allied to &. mznzima, the only other member of the genus which 
similarly combines a white crissum with a yellow forehead, I 
cannot help thinking that it will prove to be nearer Z. affinzs. 
I have not been able, it is true, to compare the latter with .»od-
