DENDROICA PETECHIA PETECHIA (Linnaeus). 

 JAMAICAN YELLOW WARBLER. 



Similar to D. (vstiva wstiva,, but larger, especially the ])ill and feet; 

 wing more rounded, the outermost (ninth) ])rimary decidedly shorter 

 than .sixth, instead of longer; lateral rectrices with more of dusky at 

 tips and along outer side of shaft; 3'ellow of under parts averaging 

 deeper or richer. 



Adult male.- -AboxQ bright yellowish olive-green (about the same as 

 in D. cestiva CBstiwi)^ the forehead and crown more yellowish or (usu- 

 ally i) more or less tinged (often strong!}^ so) with orange-ochraceous, 

 but never with a sharply defined patch of this color; rump slightly 

 more yellowish than back; greater wing-coverts and remiges dull 

 slate-blackish, edged with yellowish olive-green, these edgings broader 

 and decidedly yellow on greater coverts and tertials; middle wing-cov- 

 erts broadly tipped with yellow; middle pair of rectrices and outer 

 webs of other rectrices dusky olive, the outermost narrowly edged 

 with 3^ellow; inner webs of three outer rectrices yellow to the shaft, 

 the next yellow very nearl}" to the shaft, the fifth with marginal half 

 ormorej^ellow — those with most yellow having a wedge-shaped termi- 

 nal space of dusk}'; sides of head (including lores and superciliar}^ 

 region) and entire under parts rich lemon or gamboge yellow, the chest 

 and sides streaked with cinnamon-rufous or light reddish chestnut; 

 maxilla dusky with paler tomia; mandible more grayish (pale bluish 

 gray in life^); iris brown; legs and feet brownish (in dried skins); 

 length (skins), 110-127 (118.5); wing, Q^^kS (65); tail, 1:8-53 (50.3); 

 exposed culmen, 9-11 (lO.i;); tarsus. 20-22 (20.5); middle toe, 11-12 

 (11.1).^ 



Adult feinale. — Above (including pileum) dull yellowish olive- 

 green, more or less tinged with gra}', especially on back and scapu- 

 lars; greater wing-coverts and remiges grayish dusky with light 

 yellowish olive-green or yellowish gray edgings, the.se broadest on 

 greater coverts and tertials, narrower on secondaries and primaries; 



'Six specimens, from Jamaica. A single adult male from Haiti measures as fol- 

 lows: Wing, 63; tail, 46; exposed culmen, 11; tarsus, 21; middle toe, 12. In colora- 

 tion this Haitian specimen agrees in the main very closely with Jamaican examples, 

 but has the forehead and crown olive-yellow with a mere trace of orange-ochraceous, 

 and the dusky color of the remiges and middle rectrices is not so dark. It is possible 

 that a series from Haiti might show constant differences, thus requiring separation 

 of the birds from that island from those of Jamaica.
