from typlcftl vieilloli, from Cartliuj?enft. In tlu» collection of the 

 lMiilu<l»'i|)liitt Actt<ifiiiy I find a single spocimcn lal)clli>d "iS. rii/im- 

 iiilla," witliont indication of locality, which dillcrs decidedly from 

 nil others I have geen in being niiicli Hnialler, and in having the 

 oruiifre-hrown of the head and throat extending farther down as a 

 l>roii(l lappet over the neck to the jnguluiti, instead of being conlint-d 

 to Mie head alone. The lateral tail leather has perhaps less yellow 

 on its o' T web, though the markings of the tail and wings are 

 very sin The size is consideraltly less ; the wings lialf an inch 



shorter ; t'* . 'ddle toe and claw one-tenth of an inch shorter ; the 

 itill is nioiu slender ; the wing formula is the same. Of its distinction 

 from rieilloti 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 e.xtension of the rufous of the throat, with ihe 

 Sijiria ruficapilla of Vieillot, as cited above, from Martinique ; and 

 it may be really a West Indian species.

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

 oaffron replaced by clear yellowish, except on top of head and nape, which

 It^aving only a dusky patch on the e .rs. 



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

 and the culiacn is straighter than in any other i)t'/i(//'o/ca. The nos-
