General Notes. 
middle of the breast, the sides of which are deep bluish-gray, almost as 
dark as the back. The upper part of the throat (not the chin) is strongly 
tinged with pale yellow. The measurements are as follows : — wing, 2.40 ; 
tail, 2.10 ; bill, from nostril, .35; tarsus, .65 ; middle toe, .42. 
This being, as Mr. Purdie remarks, the seventh specimen thus far col- 
lected, the validity of H. leucobronchialis may be considered as established 
beyond question. The variations in plumage and the sexual differences of 
coloration appear to be nearly the same as those of H. chrysoptera , but 
there seems to be a frequent tendency to assume more or less of a yellow 
tinge beneath, especially on the breast, which is rarely to be noticed in 
H. chrysoptera, although sometimes slightly indicated in that species. It is 
not unlikely that there may be specimens of this species in the possession of 
collectors who have mistaken them for individuals of H. chrysoptera, and 
in view of this probability it would be well for those having the latter in 
their collections to examine them critically. The species, in all stages, 
may be readily distinguished by the entire absence of black or dull gray 
on the throat (only the bases of the feathers being sometimes grayish), and 
by the absence of the dusky-gray or black auricular patch. — Robert

Helminthophaga leucobronchialis in New York. — While col- 
lecting, Aug. 24, 1879, in a low swampy thicket composed of alders, small 
maples, etc , I shot a specimen of H. leucobronchialis. It was in company 
with several other species of Warblers. It was an adult male, and re- 
sembled Mr. W. W. Coe’s specimen, cited by Mr. H. A. Purdie in the last 
number of the Bulletin, in having the band of yellow across the breast and 
very slight suffusion of the throat, it differing from other specimens in hav- 
ing the wing bars whitish, whiter even than in H. pinus. The back is that 
of a typical H. leucobronchialis. — A. K. Fisher, M. D., Sing Sing, N. Y. 
Helminthophaga pinus, Oporornis Formosa, and Mniotilta 
varia breeding in Pennsylvania. — Some notice having appeared in 
a former number of this Bulletin (Vol. Ill, p. 194) in regard to the breed- 
ing of H. pinus in Pennsylvania, I think it would now be desirable to 
supplement the article kindly inserted by Dr. Elliott Coues by stating that, 
whilst lately residing in Chester and Delaware Counties, I have found the 
three birds mentioned at the head of this note to be the commonest 
representatives of their family in that part of the State, and that I can, 
during any of the summer months, secure a goodly number of specimens 
in the nearest belt of woodland. I found two nests of the Blue-winged 
Yellow Warbler and one of the Kentucky Warbler in 1878, and saw 
another nest of the same species found by a schoolmate, and secured one of 
the eggs. A collector in West Chester, Penn., told me that he had se- 
cured six nest complements of 0. formosa and three of H. pinus in a 
single season.
