 Vol. XXI DESCRIPTION OF A NEW SUBSPECIES OF PIPILO FUSCUS By HARRY C. OBERHOLSER A SERIES of towhees from the middle portion of the peninsula of Lower California appears to belong to an undescribed subspecies. .Though oc- cupying a geographic position intermediate between Pipilo fcus seni- cula of northern Lower California and Pipiio fuscus albigulus  of the Cape San Luca s region, they are, nevertheless, sufficiently different from both to render their subspecific separation desirable. We accordingly purpose for them the name  lipilo fuscus aripolius, subsp. nov. chars. subsp.---Similar to Pipilo juscus 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 E. A. Goldman; original number, 11747. Pileurn 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 nar- 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 terials, 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, .bu 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 ochraee- 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) min.; 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) nm.; 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 (albicomus). and should in this connection stand as albigulus to agree in gender with lilo.
