ually but rapidly in extent toward middle pair, which usually (but not 

 always) have a ver}^ small terminal spot of white; outer webs of 

 scapulars white, forming a conspicuous broad stripe on each side of 

 back; wings black, the middle coverts broadly tipped with white 

 (forming a conspicuous band), the greater coverts edged with white 

 (more broadly at tip and on innermost coverts) , the secondaries edged 

 with white (broadly so on tertials), the primaries ver}^ narrowly 

 edged with pale gray, the outer web of outermost one conspicuously 

 edged ^\ath white; sides of head and neck gray (about no. 6), fading 

 into paler gray (no. 8 or no. 9) on under parts, the latter fading into 

 grayish white on abdomen and under tail-coverts; lores gray, vrith. a 

 more or less distinct black spot against anterior angle of eye; axillars 

 and under ^ving-coverts very pale gray or grayish white ; inner webs 

 of remiges broadly edged with white, that of the ninth (abbreviated) 

 primary wholly white; maxilla blackish or dusky (sometimes paler in 

 dried skins), probably bluish gray in life; mandible paler (light bluish 

 gray in life ?) ; legs and feet dusky olive in dried skins (bluish gray or 

 gra^-ish blue in life?); length (skins), 126-143 (133); wing, 68«-81 

 (76.1); tail, 58-61 (59); exposed culmen, 12.5-13.5 (12.9); tarsus, 

 18.5-19.5 (18.9); middle toe, 11-12 (11.5).^

Adult male. — Pileum and nape black, the tips and edges of the 

 distinctly outlined feathers glossy blue-black or dark steel blue; 

 interscapular region black, faintly glossed with bluish, the feathers 

 slate-gray beneath the surface (these usually showing through, more 

 or less) ; a gray collar across hindneck (some of the feathers usually 

 having the tip black); scapulars white, the posterior feathers mixed, 

 more or less, with black; rump and upper tail-coverts plain gray 

 (no. 6 or light slate-gray) ; tail black, abruptly tipped with white 

 (the white much broader on outermost rectrix and narrowing grad- 

 ually, but rapidly, to the middle pa'r, on which the white is reduced 

 to a very small terminal spot), all the rectrices, except outer pair, 



a In the specimen (from Panama) showing this minimum wing-measurement the 

 primaries belong to the immature dress and are besides somewhat worn; the measure- 

 ment is therefore not a fair one for comparison. 



b Five specimens.
