There remain eleven species which it is perhaps best, on the whole, 

 to assign to the class of accidental visitants, at least for the present : 



Uria lonrvia, Con'its corax pri?icipa/is, 



Stercorarius parasiticus, Xanthocephalus xairthocephalus, 



Rissa triiiactyla, T/iryot/iorus ludoi>iciamis, 



Pelecanus crythrorhyncJios, B(Co/(pIius bicolor, 



Somateria spectabilis, Poli(ptila cceru/ca. 

 Synip/ieniia scniipalniata. 



Among the one hundred and six species known or believed to breed 

 in this locality there are none strictly referable to the Canadian Fauna, 

 and but seven, Cen turns carolinus, Empidonax virescens, Cardinalis 

 cardinalis, Spiza americana, Stelgidoptcryx scrripcnnis, Ictcria virens, 

 and Wilsonia viitrata, which are Carolinian in their faunal affinities, 

 and it is to be further noted that of these only two, Empidonax 

 virescens and Wilsonia niitrata, appear to be at all common and regu- 

 lar during the breeding season. With these exceptions the species 

 which are of \alue in predicating the faunal position of the locality are 

 all more or less characteristic of the Alleghanian Fauna, either in their 

 northward or southward dispersion in the breeding season. The local 

 species which in their breeding range to the southward are limited to 

 the Alleghanian Fauna are Merganser scr rater, Rallus virginiani/s, 

 Porzana Carolina, ^Egialitis meloda circumcincta, Empidonax minimus, 

 DolicJionyx oryzivorns, Cafpodacus purpureus, Passerculus sand- 

 loichensis savanna, Melospiza georgiana, Zamelodia ludoviciana, Irid- 

 oprocne bicolor, Dendroica pensxlvanica, and Hylocichla fuscescens. 

 The region under consideration may safely be considered as included 

 within the Alleghanian Fauna, although with a slight admixture of the 

 Carolinian element. It is to be regretted that a more extended study 

 has not been made of the birds of the lake shore plain, as it would be 

 interesting to know to what extent and why its avifauna differs from 

 that of the north shore of Lake Erie, which is considered to be Caro- 

 linian in character throughout, and to carry that life-zone into western 

 New York.
