P. canadensis obscurus from the Northwest Coast as a good species, while 
he has no doubt of the complete intergradation of the Rocky Mountain 
form capitalis with the Eastern canadensis. 
In relation to the habits of the species mentioned, the Report contains 
much that is new, and altogether forms one of the most valuable of Mr. 
Henshaw’s important contributions to the history of the birds of the “ Far 
West”— J. A. A. 
Cory’s Birds of the Bahama Islands. — The recently published 
results of Mr. Cory’s eminently successful exploration of the Bahama Isl- 
ands in the interest of ornithology * forms a valuable addition to our 
knowledge of the birds of these islands. Of the 149 species recorded, all 
but about 30 were met with by Mr. Cory, the remainder being given on the 
authority of the late Dr. Henry Bryant, and Messrs. Moore and Brace, 
but mainly on that of Dr. Bryant. A few are for the first time enumerated 
as inhabitants of the Bahamas. In addition to the short descriptions of the 
species, the relative abundance and distribution of the species is noted, to 
which is frequently added a short account of their habits. One species 
(Ardea cyanirostris ) is described and figured as new ; it is closely allied 
to the Louisiana Heron ( A . leucogastra leucoprymnd) , from which it is 
alleged to differ in the color of the bill, which has the terminal third 
black and the remainder sky-blue instead of yellow, and in the plumage 
being somewhat darker. The other species figured are Crotophaga ani , 
Mimocichla plumbea, Spindalis zena, Saurotliera bahamensis , Phoenicopterus 
ruber, Dafila bahamensis , and Sterna, anosthceta. Near the close of the volume 
is given a tabular list of the species, showing their distribution, from which 
it appears that all but 32 out of the 149 occur also in the United States, 
while about a dozen are thus far known only from single islands. An 
Appendix contains a list of 36 species, whose occurrence is regarded as 
probable, but as yet not known. In point of typography and mechanical 
execution the work is elegant, and the illustrations are creditable in gen- 
eral effect, but the artist has ignored the zvgodactyle character of the foot 
in both Crotophaga ani and Saurothera bahamensis. It was evidently pre- 
pared with a view of supplying to the many visitors to these islands the 
means for the ready identification of the birds occurring there, as well as 
to record the author’s own careful studies of the bird life of the Bahama 
Islands. — J. A. A.
