genera, Horizocerus and Stelgidillias, are also characterized, and a speci-

New Birds from the Bahamas.— Mr. C. J. Maynard, in an ‘Appendix 
to Catalogue of the Birds of the West Indies’ (which Catalogue we have 
not yet seen) has published (Nov. 29, 1899) descriptions of four new 
species of birds from the Bahamas, namely; (1) Colznus bahamensis, from 
the island of New Providence; (2) Sfeotyto bakamensis, from “ New Prov- 
idence and probably Eleuthera”; (3) Dendroica bahamensis (‘‘ similar to 
Dendroica vigorsit”), from New Providence; (4) Hemotopus (sic) prati 
(provisional name), from Flemming’s Key. —J. A. A. 
Kopman on the Bird Fauna of Two Sections of Louisiana.'—This 
paper gives a comparison of the representation of 67 species in contigu- 
ous but very different portions of southern Louisiana, the fertile alluvial 
coast district and the pine barrens to the northward. ‘These two areas 
are separated by the chain of lakes formed by Lake Maurepas, Pont- 
chartrain and Borgne, and mark an abrupt transition from the alluvial 
fertile district, with its deciduous arboreal vegetation, to the pine dis- 
tricts, or ‘ pine barrens,’ which extend from the eastern border of Louis- 
iana into Mississippi. While scarcely a dozen species are restricted to 
either of these areas, the relative number of individuals of birds which 
are common to both varies so greatly as to form a strong contrast in the 
general ornithological character of the two regions, obviously due to the 
difference in vegetation and coincident conditions of environment. The 
birds listed for comparison are mainly the commoner summer residents.

Faxon and Hoffmann’s Birds of Berkshire County, Mass.? — Berkshire 
County, Massachusetts, differs so much from the rest of the State in alti- 
tude and other physical conditions as to form a well-marked region, and 
one, moreover, until recently ornithologically very imperfectly known. 
With a general altitude of 1500 to 2000 feet, and with peaks rising from 
2400 to 3500 feet, the general character of the fauna and flora is distinctly 
more boreal than that of that portion of the State to the eastward. For 
many years ornithologists were left to conjecture «s to the birds frequenting 
the higher parts of ‘The Berkshires.’ As early as 1884, however, definite
