296 REVIEW OF AMERICAN BIRDS. [PART I. 
being rusty yellowish-red, without distinguishing the throat as 
darker. These characters certainly do not apply to the Paraguay 
skins in Capt. Page’s collection, whatever they may to Brazilian 
specimens. These are moulting the large feathers of wing and tail. 
The characters given by Burmeister to the North American bird, 
viz., ‘under parts white, the anal and crissal feathers alone rusty 
yellowish-red,” do not belong to it, as shown above. 
In this connection I may state that in the collection is a specimen 
of H. rustica, of Europe, taken at sea during a voyage from Norfolk 
to Rio Janeiro, probably carried westward by the prevailing winds 
in the equatorial region. 
Should, as is very probable, the South American bird prove identi- 
cal with the more northern one, the name rufa must be adopted as 
having the priority. 
Specimens in the collection from the whole United States from 
Atlantic to Pacific, and north to the boundary ; also—

TACHYCINETA, Cab. 
T ichycineta, Cas, Mus. Hein. 1850-1, 48. (Type H. thalassina, Sw.) 
Nostr‘ls lateral, overhung or bordered internally by incumbent membrane. 
Tarsi with the tibial joint covered by overhanging feathers, adherent a short 
distance along inner face, about equal to middle toe without claw. Lateral 
toes equal. Adhesion of basal joint of middle toe variable. Tail emarginate 
only, or slightly forked; fork not exceeding half an inch in depth. Color 
blue or green above, with or without metallic gloss; with or without white 
rump. Entirely white beneath. 
Under this head I combine several variations of form which shade 
so gradually into each other that I can scarcely define them even as 
subgenera. The type (thalassina) differs from all the others in a 
small, narrow bill, weak feet, more extensively feathered tarsus, and 
in a peculiar softness of the plumage without metallic gloss, seen
