REVIEWS AND BOOK NOTICES. oS ED 
opportunities for contributing this information are both ample and 
inviting. The nomenclature adopted is not a late one, and many 
of the species are only nominal, though’ the competent ornitholo- 
gist will make the required changes without difficulty in most 
cases. We note the appearance of a certain “ Hirundo Unalash- 
kensis? Gmelin”—a species neither identified of late years, nor 
now determined by Mr. Dall. Troglodytes Alaskensis Bd. is prop- 
erly reduced to a variety of byenatis (Cf. Key N. A. Birds, p. 
851): but Melospiza “ insignis,” which ought to be similarly 
treated, stands, as do Aquila ‘“ Canadensis,” Brachyotus ‘* Cas- 
sini,” Leucosticte ‘* griseinucha,” Passerculus “ Sandwichensis,” 
Corvus “ carnivorus,” Pica “ Hudsonica,” and many other mere 
varieties or pure figments. Among interesting occurrences may 
be noted a second American specimen of Limosa uropygialis, lately 
added to our fauna, and Moreca penelope. By this and his pre- 
vious paper, Mr. Dall has made himself our chief authority on the 
birds of our newly acquired territory. 
With Mr. Allen’s late “ Reconnoissance,’ Messrs. Holden and 
Aiken’s paper,* just out, Mr. Ri way’s, for the coming Re- 
port, the still unpublished explorations of Dr. H. C. Yarrow and 
rriam, Lt. Bendire’s partially elaborated operations 
in Arizona, and we may be permitted to add, the whole results of 
Dr. Hayden’s investigations, now in preparation by ourselves — 
the birds of the interior western territories are getting such an 
overhauling as they have not had for the past fifteen years. The 
editor of the Holden—Aiken paper says, * The following interest- 
ing notes were prepared for my own private perusal, and not 
designed for publication. They are possessed’of too much in- 
terest to be withheld, embodying as they do the careful observa- 
tions of two promising young ornithologists who have opis 
at different seasons of the year, a comparatively new field.” The 
editor is thus responsible for the ‘‘get-up” of the paper; and this 
dovetailing the independent researches of different observers has 
n done i in a way that reminds us of the alleged fact, that Homer 
nodded once. For we are left in ignorance of, or to find out if we 
can, the localities of observation. * Wyoming and Colorado Terri- 
tories” cover a good deal of ground, and much of the edge is taken
