 Gnateniala. Bahamas. Cuba. Breeds throughont its United States range. 

 Winters on the .southern United States border and southward. 



Cii. sp. — Cano-ccerulea, infra canescenti alba, alts fmcis cano 

 limhutis, Cauda nigra, rectrice externa alhd,secundd alhodimidiatd, 

 tertia albo-terminatd, orbitis albis, rostra pedlbiisque nipris. S 

 veriice marjis cccrulescente, f route cum strigd superclliari nigrd; 

 9 vertice dorso concolore, p'onte et superciliis innotatis. 



^, adult : Grayish-blue, bluer on the crown, hoary on the rump, the fore- 

 head black, continuous wifh 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 

 innt^r 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 

 oneabout half white, the third one tijjped with white. Bill and feet black. 

 Length, 4^-.') ; extent, 6|r-7 ; wing, 2-2^ ; tail about the same. 



$: Like the <?, but duller and more grnyish-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 

 exam[)les, 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.
