found to be of a very decided cream color, approaching buff, 

 while those of the Acadian, if anything, are more buffy, but will 

 now and then be found to be fully as pale as some of the Traill's. 

 The markings, too, are subject to considerable variation as to 

 precise shade, number and size. 



On this point Dr. Wheaton remarks, that while he can discov- 

 er no specific difference in the eggs of the two birds, he is of the 

 opinion, that the eggs of acadicus average a little longer and 

 slenderer than those of Traillii, and have perhaps a yellower buff 

 tinge. 



With reference to the habits of these two species, Dr. "Whea- 

 ton has always observed a very decided difference, especially in 

 the localities chosen as homes, and considers " the locality as 

 characteristic of the species as any of its other points." He 

 has always found Traill's Flycatcher a lover of the low grounds, 

 and especially fond of the willow clumps along running streams, 

 while of the Acadian he says : " It is never found in company 

 with, or in such localities as are frequented by the Traill's. In 

 all cases it is found in upland woodland, preferably, and I might 

 almost say as far as my observation extends in beech woodland. 

 I have never seen it even during the migration in other pla- 

 ces." 



ON THE OCCURRENCE OF CERTAIN BIRDS IN THE NEW 

 ENGLAND STATES. 



BY WM. BREWSTER. 



It must be admitted that the knowledge which we possess of 

 the geographical range of even the commonest of our North 

 American birds is at present but imperfect. 



Important and interesting as this branch of ornithological 

 lore may be regarded and receiving, as it has of late, consider- 

 able attention, it yet admits of much closer study. Local lists 

 have proved of great value as offering readily available expo- 

 nents of desultory field work, and it is to them that we must 

 often turn for our most valuable notices of rare species. The 

 component species of these lists are classed under two heads— 

 those which more or less regularly occur in the district treated 

 — and others, extralimital by right, but which driven before
