with trace of a notch at tip. Rictus with fairly developed bristles * 
extending nearly or quite to nostrils, here differing from any other 
species of the genus. Eyes, dark brown ; tarsi and toes, pale brown- 
ish ; claws, paler. Dimensions: Length, 4.75; wing, 2.50; tail, 
1.85 ; culmen, .44, from nostril, .34 ; tarsus, .70. 
The discovery of additional specimens may 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 species is described from a single specimen, taken by the 
writer at Madisonville, Hamilton County, Ohio, on May 1, 1880* 
It has been submitted to Dr. Elliott Coues for examination, and by 
him, in company with Messrs. Kidgway and Henshaw, pronounced 
to be undoubtedly new. Its relations, according to Dr. Coues, are 
mainly with Helminthophaga pinus , although in the concealed black 
of vertex and auriculars it slightly resembles certain plumages of 
Oporornis formosa. Erom H. pinus , its nearest ally, it differs in its 
decidedly larger size, the presence of rictal bristles, the concealed 
black of vertex, and the black auriculars ; negatively, in the total 
absence of white wing-bars, white tail blotches , and ashy blue on 
wings and tail. With 0. formosa it seems hardly necessary to com- 
pare it ; its smaller size, dissimilar proportions, short tarsi, yellow 
forehead, and white margin to outer tail feathers, sufficiently distin- 
guish it from that species. A suspicion of hybridism between the 
two genera is, in the present state of our knowledge, inadmissible. 
Of its habits nothing is known, except that it was shot while 
searching for insects at the end of a maple limb about fifty feet from 
the ground. 
It is a little remarkable that this should be the third new species 
of this genus announced from the Eastern United States during the 
past six years ; f such, however, is the fact, and in all three instances 
* 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.
