struction or propagation of the different species, so that they should 

 at last assume their present character and limits. 



Mr. F. W. Putnam alluded to the distribution of ^ome of our fresh- 

 water fishes in Lake Superior, Lake Champlain, and the lakes of 

 Maine, where, out of many that were common to all, some few, found 

 in the others, were wanting in one. If we were to account for the 

 presence of those found in aU of them by the supposition of a pre- 

 viously existing great inland sea including all these lakes in one, why 

 are a few forms absent in some, and present in others ? It could not 

 be through their destruction by the others, for the two largest and 

 most fierce, Lepidosteus and Amia, were wanting in the lakes of 

 Maine, though present in Lakes Superior and Champlain. 



Prof Wyman referred to the occurrence of certain forms, generally 

 considered specific, within areas of exceedingly narrow limits, such as 

 that of the Bufo, found hitherto only in the town of Danvers, Mass., 

 and indeed, so far as known, confined to the hmits of a single gar- 

 den ; and of ScapJiiojms, for which there are only a few localities. 

 The theory of local creation would seem to be carried to excess in 

 supposing this species to have always remained the same in character 

 and localization. He further suggested, in view of the fact that these 

 animals inhabit very limited localities, whether it was not quite 

 possible that those species detected on Mount Washington might yet 

 be discovered to the northward, when a more complete survey of the 

 arctic regions should be made. Our knowledge of these is not yet 

 sufficiently complete to enable us to say that the species in question 

 are entirely absent from them. 



Mr. Verrill presented a paper entitled 



Additions to the Catalogue of the Birds found in the 

 Vicinity of Calais, Me., and about the Bay of Fundy. 

 By a. E. Verrill. 



Since the publication of the list of birds presented to the Society 

 last June,* which was compiled mainly from manuscript notes fur- 

 nished to me by Mr. G. A. Boardman, some additional species of con- 

 siderable interest have been found by him, which I take this oppor- 

 tunity briefly to notice. 

 Picoides hirsutus Gray. Banded Three-toed Woodpecker. Several 



specimens of this species have been obtained during the past 



severe winter by Mr. Boardman, yet they must be considered 



as rare winter visitors. 

 Contopus horealis Baird. Olive-sided Flycatcher. Summer visitant. 



Not common. Only one specimen yet obtained.
