CANADIAN FAUNA ON THE ALLEGII ANTES. 
Mr. Trippes’ note, already referred to, on “ Birds found breeding 
in the Catskills,” makes mention of the following species, all of which 
are further considered beyond: Regulus satrapa (Golden-crestecl 
Kinglet), Sitta Canadensis (Canada Nuthatch), Anothnra' hyemalis 
(Winter Wren), Dendrceca Canadensis — D . coerulescens (Black- 
throated Blue Warbler), Dendrceca coronata (Yellow-rumped War- 
bler), Dendrceca virens (Black-throatecl Green Warbler), Jitnco 
hyemalis (Slate-colored Snowbird). 
1 he wide faunal diversity bdtween continuate regions indicated in 
the above comparison of characteristic birds, is called for by the com- 
plete and abrupt physiographical changes which give rise to the 
Catskill range, the eastern end of which “ stands isolated on three 
sides by deep and broadly open valleys, as a mighty promontory, to 
within ten miles of tide water in the Hudson River.” 
How far southward the Fauna of the Alleghany range preserves 
the Canadian characteristics possessed in the Catskills, and under 
what restrictions and modifications, is an interesting question; but the 
reply is not yet, although scattered notices of the occurrence in sum- 
mer and, in some cases, the breeding of birds southward of their 
usual range, in the Alleghanies, allow an insight into what it will be. 
Apropos to this subject are some remarks by Professor E. D. Cope 
in a paper entitled “ Observations on the Fauna of the Southern 
Alleghanies 
“ In Giles County, E. Virginia, at an elevation of five thousand 
feet, I observed in August, 1867, the following species of birds : 
Jnnco hyemalis , Dendrceca icterocephala [= D. Pennsylvanica\ D . 
Blackburnice, D. coerulescens , D. maculosa, D. virens, Myiodioctes 
Canadensis, M. mitralus [sic], Panda Americana, Mniotilta varia , 
is common here [Esopus] and annoys me much by robbing birds’ nests. Last summer [1881] a pair 
built their nest in a Norway spruce that stands in a thick grove near a gentleman’s country house 
adjoining my place.” I am myself almost positive of having seen one of these Crows, in June, near 
Rondout, perched upon a spile far out in the here shallow river; and also feel almost satisfied that, 
on different occasions, I have seen the Rough-winged Swallow at the same locality, where un- 
doubtedly it occurs.
