DENDKUICA. 205 



from typical vieilloti, from Cartbagena. In the collectioa of the 

 Philadelphia Academy I find a single specimen labelled "*S. rufica- 

 2ytlla," without indication of locality, which differs detidedly from 

 all others I have seen in being much smaller, and in having the 

 orange-brown of the head and throat extending farther down as a 

 broad lappet over the neck to the jngulura, instead of being confined 

 to the head alone. The lateral tail feather has perhaps less yellow 

 on its outer web, though the markings of the tail and wings are 

 very similar. The size is considerably less ; the wings half an inch 

 shorter ; the middle toe and claw one-tenth of an inch shorter ; the 

 bill is more slender ; the wing formula is the same. Of its distinction 

 from vieilloti as a species I have little doubt, and can only regret 

 the uncertainty in regard to the locality. It agrees very well, espe- 

 cially in the greater extension of the rufous of the throat, with the 

 Sylvia ruficapilla of Yieillot, as cited above, from Martinique ; and 

 it may be really a West Indian species.

 ITab. Mexico (both coasts to the southward) ; Guatemala. 



Head and neck all round, with jugulum, brownish-saffron, with a greenish 

 tinge on the nape. Rest of upper parts ashy. Middle and tips of greater 

 wing coverts white, forming two bands on the wing ; a third white patch at 

 the bases of the primaries (except the two outer), and extending forwards 

 along the outer edges. Secondaries edged externally with olive green. Inner 

 webs of quills conspicuously edged with wliite. Under parts, except as de- 

 scribed, white, tinged with brownish on the sides ; a narrow frontal band, and 

 a broad stripe from this through eye and over ear coverts, black. Outer tail 

 feather white, except at base and towards tip ; greater portion of inner web 

 of next feather also white, much more restricted on the third. 



Length, 4.60; wing, 2.88 ; tail, 2.15 ; tarsus, .75. 



A female specimen (14,369), perhaps also in autumnal plumage, has the 

 saffron replaced by clear yellowish, except on top of head and nape, wl)ich 

 are olive green. The black frontal and lateral bands are replaced by whitish, 

 leaving only a dusky patch on the ears. 



The bill in this species is quite peculiarly slender and depressed, 

 and the culmeu is straighter than in any other Dendroica. The nos-
