An Intergrade between Helminthophila pinus and H. leucobronchialis 

 captured in Hyde Park, Mass. — This bird, a male, was discovered by me 

 on the morning of June 13, 1907, on a hillside covered by a dense growth 

 of low oaks and birches, in the town of Hyde Park, Mass. I was drawn 

 to the bird by his song, which was identical with that of the Golden-winged 

 Warbler, being sometimes composed of three notes, zee, zee, zee, sometimes 

 of four, and once only of two. I thought likely that it might be breeding 

 here, but I could find no trace of the nest, so I decided to return in the 

 afternoon and shoot the bird if it could be found, in order that a proper 

 examination and record of it might be made. 



I returned about three o'clock and shot it near the place where I had seen 

 it in the morning. The description and measurements of this specimen are 

 as follows: 



Crown yellow, with a few dark feathers. Back and wings greenish yel- 

 low, some of the wing feathers being bluish gray edged with greenish. 

 Tail bluish gray above, the three outer pairs of feathers partly white. 



like those of //. chrysoplera. — Walter Faxon, Lexington, Mass. 



Helminthophila leucobronchialis (Brewst.) in Lexington, Mass. — On 



the 14th of June, 1907, while walking in company with Dr. Winsor M. 

 Tyler through a hillside pasture sloping down to a wooded swamp in the 

 town of Lexington, Mass., I came upon a male Brewster's Warbler in full 

 song. This bird was often scrutinized by Dr. Tyler and myself at short 

 range and with the aid of powerful glasses, from this time forth up to the 

 end of June, about which time it stopped singing and disappeared from 

 view. It wore the pure, unadulterated leucobronchialis dress, revealing 

 not the slightest trace of yellow on the lower parts, even when seen at 

 close quarters and by the aid of the most favorable light. Its crown was 

 bright yellow, lores black, this color continued behind the eye as a short, 

 thin postocidar streak (as in H. pi.nus). Back gray (as in H. chrysoplera). 

 Wing-patch yellow, indistinctly divided into two bars. Lower parts silk- 

 white, purest on the chin and throat. 



There were two male FI. chrysoplera in the immediate neighborhood — 

 so near that all three could be heard singing at the same time. The 

 Brewster's Warbler had two different songs, absolutely indistinguishable 

 from two of the songs of the Golden-winged Warbler. The first of these
