Nov., 1917 NEW SUBSPECIES OF GEOTHLYPIS BELDINGI 183 cas region and those from the central portion of the Lower California peninsula. On further comparison the latter prove to represent a remarkable new subspe- cies, which I take pleasure in dedicating to Mr. Edward A. Goldman, who, with Mr. E. W. Nelson, collected the type series. OeothlYl? beldingi goldmani, subsp. nov. CHARS. suBse.--Similar to Geothlypis beldi?,gi beldingi, but male with the upper surface much duller, more brownish or grayish (less yellowish) through- out; crown behind the black mask largely or wholly grayish or whitish instead of yellow; yellow of under parts somewhat lighter and confined to throat and breast; lower abdomen white or whitish, instead of usually deep yellow, as in Geothlypis beldingi; sides and flanks paler and more grayish. Femal'e similar to the female of Geothlypis beldingi, but upper parts and sides of head paler, more grayish (less yellowish); yellow of lower parts paler and less extensive, confined to throat and upper breast, the abdomen being dull whitish, slightly or not at all washed with yellow; sides and flanks paler, more grayish. DEscR?e??o?.--Type, adult male, no. 196026, U.S. Nat. Mus.; San Ignaeio, Lower California, Mexico; October 7, 1905; E. W. Nelson and E. A. Goldman; original number, 11766. Sineiput, lores, ocular region, cheeks, aurieulars, and a narrow line extending diagonally downward and backward to the sides of the throat, black, forming a conspicuous mask; behind this a narrow line of pale grayish mixed with whitish and a little lemon yellow, and on the post- ocular region with lemon chrome; oeeiput and eervix brownish olive, verging toward sepia, with a mixture of fine streaks of lemon yellowish, these mos? conspicuous on the oeeiput, and resulting from the largely yellow bases of the feathers, which are incompletely covered by the brownish tips; back and scap- ulars dull eitrine, washed with brownish or grayish; rump similar but lighter and somewhat more grayish; upper tail-coverts of the same color as the back, but paler and of a clearer shade of eitrine; tail dark eitrine, the inner margilts of the teetrices more brownish; wings dark hair brown, the quills and coverts edged with eitrine ;. sides of neck posterior to the grayish band similar in color to the eervix, but less mixed with lemon yellow; anterior lower parts chrome yellow, paling to lemon chrome on the middle of the upper abdomen: lower abdomen dull yellowish white; under tail-coverts basally wax yellowl terminally between wax yellow and old gold; sides and flanks isabella color i thighs between tilleul buff and drab gray; edge of the wing lemon chrome; un- der wing-coverts dull grayish white, washed with lemon chrome. MrAsuura?r??s.--Male:? Wing, 61.5-65.5 (average, 63.5) mm.; tail, 64-70 (66); exposed eulmen, 12.5-14.3 (13.5); tarsus, 23-25 (24); middle toe without claw, 15-17 (15.7). Female :' Wing, 59-63.5 (average, 60.6) mm.; tail, 60-65.5 (62.1); exposed culmen, 13-13.5 (13.2); tarsus, 21.5-23 (22.2) middle toe without claw, 14-15.2 (14.4). ' GEOGRAPIt?C v?STmBU?'?ON.--Central Lower California, from San Ignacio to Comondu. l?r?a?zs.--This very distinct and unexpected subspecies is most readily distinguished from Geothlypis beldingi beldingi by the whitish crown band, the less yellowish upper parts, and whitish abdomen of the male; and the less yellowish upper surface, and paler, less extensive yel]ow of the lower parts in the female.
