DESCRIPTION OF A NEW SUBSPECIES OF PIPILO FUSCUS 
By HARRY C. OBERHOLSER 
SERIES of towhees from the middle portion of the peninsula of Lower 
California appears to belong to an undescribed subspecies. Though oe- 
cupying a geographic position intermediate between Pipilo fuscus seni- 
cula of northern Lower California and Pipilo fuscus albigulus’ of the Cape Sau 
Lueas region, they are, nevertheless, sufficiently different from both to render 
their subspecific separation desirable. We accordingly purpose for them the 
name 
Pipilo fuscus aripolius, subsp. nov. 
Chars. subsp.—Similar to Pipilo fuscus albigulus Baird, but tail longer; upper 
parts much darker and more grayish; breast, sides, and flanks, darker and less 
brownish (more purely grayish); crissum slightly, and throat decidedly, darker, and 
the latter not so much paler than the posterior lower parts. 
Description.—Type, adult female, no. 196605, U. S. Nat. Mus., Biological Sur- 
vey Collection; San .Pablo, Lower California, October 3, 1905; E. W. Nelson and HE. 
A. Goldman; original number, 11747. Pileum brown, between dark russet and hazel, 
the feathers edged with mouse gray; cervix, back, scapulars and rump, between 
mouse gray and hair brown; but the centers of the feathers on the interscapulum 
with a distinct wood brown tinge; upper tail-coverts between olive brown and deep 
olive, with narrow tips of tawny olive; tail fuscus, the rectrices with narrow tips of 
deep ochraceous tawny; wings rather dark hair brown, but the outer primaries mar- 
rowly edged with pale smoke gray, the remaining primaries, together with the sec- 
ondaries, edged with hair brown, the outer webs of the greater wing-coverts like the 
centers of the feathers on the interscapulum; rest of the wing-coverts, together with 
tertials, margined with rather light mouse gray; lores, mastax, malar region, and 
eye-ring, cinnamon, more or less mixed with gray and chaetura drab; auriculars 
chaetura drab, streaked with pure light grayish; superciliary stripe, supra-auricular 
region and the sides of the neck, gray like the scapulars; posterior auricular region 
tinged with cinnamon; chin and throat cinnamon, but the posterior portion of the 
latter cinnamon buff, this throat-patch streaked or spotted all around, though in 
places obscurely, with chaetura drab; breast and sides of body between light drab 
and mouse gray; flanks of the same color but washed with ochraceous; center of 
breast dull white; center of abdomen creamy white; crissum between tawny and ochrace- 
ous tawny, but nearer the latter; thighs like the sides of the body but somewhat darker; 
lining of wing gray like the sides of the neck, but the feathers margined with whitish or 
pale buff. 
Measurements.—Male (three specimens, from Lower California): wing, 88.5-92 
(average, 90.5) mm.; tail, 103-107.5 (105.2); exposed culmen, 14.5-14.8 (14.7); tarsus, 24- 
26.5 (25.3); middle toe without claw, 17-18.5 (17.8). = 
Female (five specimens, from Lower California): wing, 81-92.5 (average, 86.8) 
inm.; tail, 96.5-105 (100.5); exposed culmen, 14-15 (14.4); tarsus, 25.5-26 (25.9); middle 
toe without claw, 17-18.8 (17.9). 
Geographic distribution.—Middle portion of the peninsula of Lower California, 
south to Guajademi, at about 26° 30’ north latitude, and north to Santa Rosalia Bay, at - 
about 28° 40’ north latitude. 
Remarks —This new subspecies is similar to Pipilo fuscus senicula, but is 
lighter and somewhat more grayish (less brownish) on the upper surface, more 
grayish on the breast, sides and flanks, nearly pure white (not buff or cream — 
color) on the middle of the lower breast and the upper abdomen. The throat is 
‘The subspecific term albigula is a perfectly good Latin adjective, like albicoma —
