bluish on the fiiles, and with browni:^li iK'hind. Tail leathers black ; the first and second 

 edged and tipped with white ; involvinj; the entire outer web of the first, and most of that 

 of the second ; the tliird with only a very faint edging of the same. Female without the 



black superciliary line. Length, 4.50 ; extent, .5.50 ; wing, 1.80 ; tail, 2.30. Iris brown ; 

 biU and feet black. 



Hab. Valley of Colorado and Gila. 



This species was a winter resident aliotit Fort Mojave, in small numbers, 

 and undistingnishable in habits or general appearance from the two other 

 species found tliere. I shot one on the 20tli of Februaiy, which had a cry 

 of alanu much like that of a vrren. It seems to represent the P. mdanura, in 

 the country east of the Colorado, and probably leaves that valley altogether 

 for the moimtaius in spring. I suspect it is merely the yoimger plumage of 

 P. mdanura.
