SALVIN’S SICKLE-BILL. 
Similar to E. a. heterura, but white tips to rectrices averaging larger 
and always much purer white.° 
Adults (sexes alike)—Above metallic bronze-green or greenish 
bronze, darker and duller on pileum, where feathers are narrowly and 
indistinctly margined with dusky, the upper tail-coverts (sometimes 
feathers of lower rump also) margined terminally with pale dull buffy; 
tail dull metallic bronze-green, the rectrices tipped with white, this 
most extended on lateral pair, where the basal outline of the white 
area on outer web is more or less transverse; remiges blackish slate or 
dusky, very faintly glossed with violaceous, the innermost secondary 
is usually marked with a narrow shaft-streak or subterminal spot of 
dull white; chin, throat, and chest sooty black sharply streaked with 
pale buff or buffy white, the breast and abdomen similarly marked, 
but streaks narrower and less strongly contrasted (the darker streaks 
more brownish); sides and flanks washed with metallic bronze-green ; 
under tail-coverts dusky (glossed, more or less, with bronze-green), 
margined with brownish buff or pale cinnamon and with a narrow 
shaft-streak of the same; maxilla black, mandible pale dull yellowish 
(in dried skins), passing into dusky terminally; iris dark brown; legs 
and feet pale brownish (in dried skins), the scutella darker, more horn 
colored. 
Young.—Similar to adults, but feathers of pileum, hindneck, back, 
and rump more or less distinctly tipped with buffy, the upper tail- 
coverts margined with the same, the greater wing-coverts very nar- 
rowly tipped with buffy, and remiges with a minute apical spot of 
dull whitish (larger on secondaries).

¢ Compared with sixteen adults of Z. a. heterura from Ecuadér, twenty adults of E. a. 
salvini (including one from Bogoté) differ constantly and conspicuously in having pure 
white tips to the rectrices, all the others having these markings dull brownish white as 
well as less in extent,
