purer yellow and broader ou tertials; outer webs of tinl-lbatluTs dusky 

 inner webs (except of middle pair) primrose-yclloAV, tipped obliquely 

 with dusky. Sides of head and entire lower jiarts rich ])urc piniboj^e- 

 yeliow, the breast and sides streaked with rufous-chestnut ; bill, black- 

 ish ; legs and feet dark brown. Length (skin) 4.{)0, Aving li.oO, tail 

 2.15, exposed culmen .40, tarsus .75. 



Adult female (^0.111115, same locality, etc.) : Above olive-green, the 

 hind-ne{;]c and scapulars tinged with grayish, and top of head more tinged 

 witu yellowish, especially anteriorly; sides of head and under parts 

 plain gamboge-yellow (much lighter and duller than iiriuale), tinged 

 with olive laterally; wings and tail much as in male, but ground-color 

 rather paler and lighter edgings, etc., less distinct. Length (skin) 4.30, 

 wing 2.35, tail 2, exposed cuimen .40, tarsus .80. 



Three other adult males do not differ essentially from the type, but 

 two adult females differ decidedly in coloration from those described 

 above, although all were taken the same day. They have the yellow of 

 the lower parts interrupted from the lower breast to the under tail- 

 coverts, the intervening space being palo dull yellowish buffy ; there is 

 a distinct narrow streaking of rufous in one specimen and a trace of 

 these streaks in the other ; the olive of the upper parts is interrupted 

 by patches of dull gray on the hind-neck, scapulars, etc. 



The three males measure as follows : Wing 2.30-2.50, tail 2.05-2.10, 

 exposed culmen .42-.45, tarsus .75-.80; the corresponding measurements 

 of the two females being 2.35, 2, .42-.45, .80. 



A young bird (sex not determined), taken the same day as the other 

 specimens, resembles m the coloration of the upper parts the two 

 females last described, except that the forehead is dull olive-grayish 

 instead of bright yellowish olive-green, and the hind-neck is more ex- 

 tensively grayish. The lower parts, however, are conspicuously dif- 

 ferent in color, being dull buffy whitish (nearly pure Avhite on lower 

 throat and chest), passing into light yellowish olive on sides and Hanks 

 and pale primrose-yellow on under tail-coverts; sides of head and neck 

 dull light brownish gray. Wing 2.30, tail 2, exposed culmen .4-4, tar- 

 sus .77. 



From I), petechia (jundlachi (Baird)* of Cuba and the Bahamas, the 

 adult male of the jireseut bird differs conspicuously in the purer yellow 

 of the under parts, which in J), gundlachi are of a very intense color, 

 approaching orange-yellow ; the upper parts are of a clearer olive-green, 

 with the whole crown and forehead abruptly and markedly different in 

 color, instead of being similar to the back, with or without touches or 

 tinge of orange-rufpus.

 One specimen, an adult male. 



* Mr. Corj's specimens were iu such wretched i)luraage that his jefereuce of them 

 to D. p. gundlachi is iierfectly excv<sable.
