346 Allen, Recently Described North American Birds. [oct 



" Type locality. — Big Hatchet Mountains, Grant County, New Mexico. 



" Geographic distribution. — Extreme western Texas (in winter to cen- 

 tral part), Arizona, New Mexico, and southeastern California, south 

 over the table-lands of western Mexico to central Zacatecas ; north to 

 Colorado, southern Utah, southern Nevada, and possibly southeastern 

 Oregon. Resident south of Colorado. 



•" Type. — Male, adult; No. 126774,11. S. N. M. ; Big Hatchet Moun- 

 tains, Grant County, New Mexico, May 19, 1892; Mearns and Holzner. 



"Description. — Above uniform pale grayish sepia, slightly rufescent 

 on the rump, the feathers of which have more or less concealed white 

 spots ; upper tail-coverts hair brown, faintly barred with darker. Wing- 

 quills fuscous, indented externally with the color of the upper surface, 

 wing-coverts like the back. Middle tail-feathers, and basal portion of 

 exterior -webs of the rest, with the exception of the outermost pair, 

 hair brown, regularly barred with black ; three outer pairs with broad 

 grayish tips, and white indentations on exterior webs, these latter most 

 numerous on the outer pair; other rectrices tipped with hair brown; 

 remainder of tail black. Superciliary stripe white; lores and cheeks 

 grayish white, somewhat mixed with brown ; postocular streak like the 

 crown ; sides of neck brownish gray ; lower surface dull white, nearly 

 clear white on chin and throat, washed with gray on sides and flanks ; 

 crissum heavily barred with black ; lining of wing grayish white." 



" The difference existing between eremophilus and cryptus consists in 

 the rather paler, much more grayish tint of the upper parts, and no 

 difficulty will be experienced in identifying the great majority of speci- 

 mens. Some intermediates, however, are to be distinguished only by 

 the slightly paler or more grayish color of the wings. This subspecies 

 is more closely allied to bairdi than to any of the other Mexican forms, 

 although the ranges of bairdi and eremophilus are separated by the inter- 

 position of a race larger and darker than either. 



" As in cryptus, there exists a considerable amount of individual differ- 

 ence, even at the same season, this consisting principally in the darker 

 or more rufescent color of the upper surface. Two breeding specimens 

 from Paisano, Texas, are perfectly typical of the present race, though 

 rather darker than most Arizona examples. Specimens from San 

 Diego, Chihuahua, Mexico, White Mountains, and the region of Death 

 Valley, California, are identical with those from Arizona and New 

 Mexico. A winter bird from the Valparaiso Mountains, Zacatecas, 

 Mexico, differs only in being slightly darker."
