DESCBTPTTO^^ OF A NEW WABBLER OF THE GENUS 



HELMINTHOPHAGA. 



By Frank W. Langdon. 



Helminthophaga cincinnatiensis, sp. no v. 



Plate VI.) 



Adult male; spring plumage. Entire upper parts, excepting fore- 

 head, clear, bright, olive green, with a tinge of yellowish in certain 

 lights; quills and rectrices dark plumbeous brown, their outer webs 

 fringed with olive green like that of the back. Below, including crissum, 

 bright cadmium yellow, of nearly the same shade throughout. Fore- 

 head, bright yellow, this color bounded anteriorly by a A^ery narrow 

 black line from lores, and behind gradually merging into the clear 

 olive green of crown ; feathers of vertex with a median concealed area 

 of black. Lores velvet}^ black; auriculars black, tipped with yellow- 

 ish-green, giving them a mottled appearance. A yellow area beneath 

 the eye separates the black of lores from that of auriculars. 



Greater and lesser wing coverts tipped with greenish-^^ellow, forming- 

 two indistinct wing-bars; outer primar}- edged with whitish. Inner 

 webs of two outer tail feathers narrowly margined with white near 

 the tip. 



Bill, in the flesh, black, excepting extreme tip, and base of lower 

 mandible, which are bluish horn-color; culmen slightly decurved, with 

 trace of a notch at tip. Bictus with fairly developed bristles* extend- 

 ing nearl}^ or quite to nostrils, here differing from any other species of 

 the genus. Eyes, dark brown; tarsi and toes, pale brownish; claws, 

 paler. Dimensions: Length, 4.75; wing, 2.50; tail, 1.85; culmen, .44, 

 from nostril, .34; tarsus, .70. 



The discovery of additional specimens ma}^ modify the above de- 

 scription somewhat, for, as Dr. Coues suggests to me, the concealed 

 black of vertex would seem to indicate that this specimen had not 

 quite attained its full spring dress. 



"The presence of this character would by some authors be deemed sufficient reason for 

 the institution of a new genus or sub-genus, but this, it seems to me, would be unnecessary 

 and inadvisable
