with usually yellow wing-bars ; and between the three occur all 

 sorts of intermediates. From this last pale form a series that I 

 have collected near New Haven stretches without a break to typi- 

 cal specimens of Brewster's Warbler (If. leucobronchialis) with 

 pure white lower parts and bluish gray back, the yellow last show- 

 ing in the center of the breast. All three forms seem, to an extent 

 at least, to breed true ; although all the evidence tends to show 

 that they mate together indiscriminately, and their song is indis- 

 tinguishable. I took in the same piece of woodland August 9, 

 1904, an adult male and young each of the bright yellow form 

 with yellow wing-bars. Two young taken with a female Brewster's 

 Warbler near New Haven on July 4, 1893, prove on further com- 

 parison to have the yellow of the breast paler than in young 

 Blue-winged Warblers of the same age ; about half a dozen males 

 showing in varying degree the character of Brewster's Warbler 

 have been taken in one small piece of land within a few years ; 

 and on May 12, 1898, I collected two males within a few hundred 

 yards of where I knew one was breeding the year before, and 

 where I had taken one on May 8, 1896. 



If H. leucobronchialis were a species and the intermediates hy- 

 brids between it and H. pinus it would certainly be true that in 

 the majority of instances it would mate within the species, and 

 such an occurrence seems never to have been observed, and as its 

 white throat is not found in either H. chrysoptera or H. pinus it 

 can hardly be a hybrid between them. That it is merely a phase 

 of H. pinus is the only alternative left us. 



Before discussing the plumage of the bird called Lawrence's 

 Warbler (Zf. lawrencei), let us spend a few minutes in seeing 

 what may be learned from the localities in Connecticut where it 

 has been taken, and the distribution of the Blue-winged and 

 Golden-winged Warblers in this State. Helminthophila pinus is 

 an abundant summer resident of the coast, becoming rapidly rare 

 farther north, but breeding at Bethel on the west, and Warren, 

 and rarely at Portland, on the north : H. chrysoptera, however, is 

 rare throughout the State, and is apparently absent along the 

 coast east of New Haven. It occurs rather commonly at Port- 

 land, but breeds also at Bethel, and doubtless also at Bridgeport, 

 Seymour, and New Haven, where it has been taken at the begin-
