REVIEWS. 371 
(Aleutian Islands), noticed in 1858, by Professor Baird, though not for- 
mally introduced for want of specimens, is here more definitely charac- 
terized; and one L. littoralis n. s. (Sitka and Fort Simpson) is described; 
the latter is considered to be what Elliot figured under the name of gris- 
einucha (nec. Brandt), than which species, however, it “is considerably 
maller; the colors are brighter and lighter” (p. 318), and the 
areas upon the head are somewhat different. Melospiza insignis, n. s. 
from Japan, ete o n uced fi 
(Dall); Schlegel has it from Sitka. Fulmarus Rodgersi (Cassin, Pr. A. 
N. S., Phil., 1862, 290, and Coues, ibid., 1866, p. 29), first described, as just 
quoted, from the ** North Pacific,” was taken at St. George's Island, Mr. 
Aud., it appears to lack the great depth of bill which is a strong character 
of the latter. The last species that Professor Baird gives is the Simor- 
hynchus Cassini (Coues, Pr. A. N. S., 1868, p. 45), from Ounimak Pass; a 
Species near S. tetraculus, but much less in size, with a remarkably small, 
simple bill, and dusky, leaden colored plumage. 
In closing a rapid analysis of these two very interesting and important 
memoirs, we have only to add further, that they are accompanied by a 
number of colored plates, well illustrating all the new species, and the 
other additions to our fauna.
