This race lias a cDiisitliMalilc! rosi'iulilaiico to /'. trstivn/is, hut differs in 

 some a]t]iie(:ial)lo jioints. The hrowu of the iii)iter parts is paler, and the 

 ashy edyiiij,' to the feathers appears rather less e.xtensive. The dark hrowii 

 blotches on the hack are of greater extent, the black streaks on the back 

 continiHl to a mere streak alony the shaft. There is less of an olive tinge 

 acro.ss the breast. 



The proportions of the present race differ more from those of a'stivalvi 

 than do the colors, the bill being more .slender, and the wings and tail con- 

 sideralily longer. 



The resemblance to J', hottcvii (= wfitmdix, var. hottrrii) of Sclater, from 

 Middle Mexico (Orizaba, Colima, etc.), is very ch)se ; the difference being 

 greater in the ])roiH)rtioViS than in the colors, the latter having a shorter wing 

 and tail, with thicker bill, as in var. adivalis. In hutkrii there is rather a 

 predominance of the black over the rufous in tlie streaks above. 



Hauits. This, in its general habits, nesting, eggs, etc., probably resembles 

 the variecv a'ufwn/vi.

Sp. Char. (0,329 ^, Texas; compared with type of species.) Ground-color of 

 upper parts gr.ayish-asli ; the middU.' portion of each feather dull brown, in the form of li 

 blotch, and with a black shaft-.streak, the latter becoming modified on scapulars, rump, 

 and \ippcr tail-coverts, into transverse spots, tho.se on the upper tail-coverts being largo 

 and cons[)icuou.«, and in the form of erescentie .spots*, the terminal margin of the feathers 

 being lighter ashy in sharp contrast. Middle tail-feathers clear a.shy, with a sharply 

 defined shaft-streak of blackish, throwing olf obsolete, narrow, transverse bars towanl 

 the eilge ; rest of tail clear dusky-brown, the lateral leather with whole outer web, and 

 margin of the inner, dull white, all, except the intermediate, with a large, abruptly defined, 

 terminal .space of dilute brown (decreasing in size from the outer), the margin whitish. 

 Upper secondaries broadlj" and .sharply margined along both edges with dull ashy-white, 

 the enclosed portion being clear dusky brown, intensified where adjoining the whitish. 

 A very obsolete superciliary stripe of ashy, becoming whitish over the lore ; auriculars 

 more dingy, but without distinct .stripe along upper edge. An uninterrupted but indis-
