conspicuous feature. Its eftect is not unlike that seen in young autumnal 

 males of Dcndroica virens. \\hich have the black of the throat and jugu- 

 lum more or less similarly overlaid with yellow. 



In briefer terms, this interesting bird may be said to be about inter- 

 mediate in color and markings between typical pinus, with its short, nar- 

 row eye-stripe and uniformly yellow underparts, and the so-called //. la%v- 

 rencei, which has a broad, black patch extending from the bill through 

 and behind the eve, and the cliin, throat, and forepart of the breast 

 solidly black. It forms an important link in the chain of evidence sup- 

 porting my theory* that H. piiiiis and //. clirysoptera frequently inter- 

 breed, and that their offspring perpetuate a \ariously-characterized hybrid 

 stock by breeding back into one or the other parent strains. That this 

 is the only possible way of accounting for the now almost complete 

 series of intermediate specimens connecting the obviously distinct species 

 H. pinus and H. chrysoptcra is to m^- mind certain, despite the able argu- 

 ment to the contrary lately publishedf by Mr. Ridgway. 



Mr. Thurber tells me that the specimen just described, was shot about 

 May 15, 1SS4, two miles from Morristown, and exactly fom- and one-half 

 miles from the place where the tvpe of hizvrcncci was obtaineti. The 

 sex was not determined, but it is undoubtctih a male. The collector, 

 Mr. Frank IJlanchet. has also taken another hybrid of the '//. leucobron- 

 r/iialis' type in the same locality [as abo\e recorded by Mr. Thurberj. —

Kirtland's Warbler on St. Helena Island. South Carolina. — Mr. W. 

 W. \Vorthington, of Shelter Island, New ^'ork, has shown me a skin of 

 this Warbler which he has secured for his private collection. The sjieci- 

 men is a male in full plumage and was shot bv a native lad on the 27th 

 of .\]iril. I had suspected the existence of the species here before, but 

 was unable to secure an\- specimen. On Ma\' 3. while returning to camp 

 without my gun, I observed three specimens near the middle of the 

 Island. They were quite familiar, allowing me to approach cautiousl_\' 

 within less than a rod, and seeme'J to be at home — not tired, and yet 

 anxious to be off, as passing migi'ants usualh' are. The notes are ci' two 

 distinct characters. The first, a song, was uttered with the head held 

 forward and the body cpiite erect. It lioi-e a striking resemblance to the 

 song of the Yellow-throated \\'arbler. The seccnui was a loud chipping, 

 uttered while mo\ing about among the bushes, and was kej'it up I'or a 

 space of one or two minutes at a time. Resting a few seconils the bird 

 woulil begin again, creeping about the branches and ■swapping ends' 

 with a cpiick, I'erking movementall the time. Arrixing near the top of the 

 bush or the end of the branch he would settle himself and sing two oi' 

 three times before fluttering to the next bush. All these specimens were 

 in low bushes and seemed to prefer them to trees. For though there were
