118 EXPLORATIONS AND SURVEYS WEST OF 100TH MERIDIAN. 



close vicinity of the streams. In some places it was not uncommon, 

 usually in small companies of from three to eight. I never saw it near 

 the pines, and, at this season at least, doubt it ever being found among 

 them. Indeed, all its habits and motions, as it busies itself searching 

 for food among the rocks and bushes, are exceedingly similar to the 

 Song-Sparrow (M.fallax), for which I mistook it more than once 5 its 

 chirp of alarm was very similar. 

 Bill dark-brown above, paler below ; legs and feet light-brown. 



77. Peuccea, sp.(?) 



Feathers above with dark-brown centers, and edged conspicuously 

 with fulvous; brightest on the rump, where each feather is broadly 

 tipped with the same; beneath pale ochraceous-yellow, becoming strong 

 fulvous on the flanks and under tail-coverts; upper parts of breast and 

 throat strongly and sides less distinctly marked with longitudinal streaks 

 of black; wing-coverts edged and tipped with strong fulvous; inner sec 

 oudaries bordered with same, but darker; tail-feathers black, margined 

 with dull-rufous; bend of wing edged with light-yellow; bill above dark- 

 brown, paler beneath. 



The above is a description of a sparrow taken at Camp Grant. It 

 was started from the long grass on the open plain, and no others were 

 seen. From a comparison made with specimens in the Smithsonian In- 

 stitution, it appears not to be the young of any species of the genus 

 known to inhabit the United States, but may perhaps be one of several 

 Mexican forms, of which the Institution has no examples. Its immature 

 condition renders it exceedingly difficult to arrive at any satisfactory 

 conclusion respecting it, and I therefore deem it best to leave its deter- 

 mination till better specimens or a larger series are at hand lor com- 

 parison. 



78. Passerella townsendii (And.), var. sclii&tacea, Bd. 



Probably very rare in this region, as a single specimen, taken in a 

 small canon south of Apache, was the only on# seen during the season.
