ties (= halophilus), which appear to be chiefly represented so far 

 in collections by breeding specimens, represent the worn summer 

 plumage of rostratus, also presents itself. The effects of abrasion 

 in fading colors, in restricting and intensifying shaft-streaks, and 

 in modifying measurements, are well known. The many experi- 

 enced workers who have studied the large series of specimens in 

 eastern museums must have given these factors due consideration, 

 so that we may be wasting space in suggesting this possibility. 

 In either case, what a remarkable exception there would be to the 

 rule of southward migration in the northern hemisphere! 



Finally, let me ask the question again — Where does the Large- 

 billed Sparrow spend the summer? 



THE STATUS OF HELMINTHOPHJLA LEUCOBRON- 

 CHIALIS AND HELMLNTHOPHLLA LAW- 

 RENCE! l 



BY LOUIS B. BISHOP. 



In the way of theory as to the status of the puzzling specimens 

 labelled with these names I have nothing new to offer, but wish 

 simply to bring to your attention a few facts that seem to go far 

 to establish an old theory, first advanced, I believe, by Mr. Chap- 

 man. 



In southern Connecticut there are three distinct forms of the 

 Blue-winged Warbler {H. pin us), taking males alone into consider- 

 ation — the ordinary form with rich gamboge-yellow lower parts, 

 white wing-bars and bright olive-green back ; a second form, 

 like the last but with gamboge-yellow wing-patch, resembling the 

 Golden-winged (/I. chrysoptera), which is much the rarest; and, 

 third, a form with pale yellow lower parts, much paler back, and
