CH. SP. Cano-ccerulea, infra canescenti alba, alis fmcis cano 

 Umbatis, caudd nigrd, rectrice externd albd,secundd albo-dimidiata, 

 tertia albo-terminala, orbitis albis, rostro pedibusque niyris. $ 

 vertice magis ccerulescente, f route cam striga superciliari nigrd; 

 9 vertlce dorso concolore, fronte et superciliis innotatis. 



J , aflult : Grayish-blue, bluer on the crown, hoary on the rump, the fore- 

 head black, continuous with a black superciliary line. Edges of eyelids 

 white, and above these a slight whitish stripe is commonly observed bordering 

 the black exteriorly. Below white, with a faint plumbeous shade, particu- 

 larly on the breast. Wings dark brown, the outer webs, especially of the 

 inner quills, edged with hoary, and the inner webs of most bordered with 

 white. Tail jet-black, the outer feather entirely or mostly white, the next 

 oneabont half white, the third one tipped with white. Bill and feet black. 

 Length, 4i-5 ; extent, 6^-7 ; wing, 2-5>; tail about the same. 



$: Like the $ . but duller and more grayish-blue above; the head like 

 the back, and without any black. Bill usually in part light colored. 



The extent of white on the tail varies somewhat ; but I have seen no 

 eastern specimens in which the outer feather was not white in all of its 

 extent which was not covered by the under coverts. In some Arizona 

 examples, however, the black which usually exists at the base extends be- 

 yond the coverts, and in fact there is little more white on this feather than 

 there is in P. plumbea, though the black of the frontlet is intact.
