278 REVIEW OF AMERICAN BIRDS. * [PART I. 
This is a smaller species than the Progne furcata,’ from Chile 
(9,112), with the tail, however, nearly as long and proportionately — 
almost as much forked. It is much more richly colored, however; 
the concealed middle portion of the anal feathers white, not dart 
brown, ete. The feet are much smaller. 
A Progne collected by Mr. Wright, at Monte Verde, is duller in 
color than that from Remedios, but has still more concealed white 
below, in the median portion, not only of the anal feathers, but of 
those of the entire crissum and of the belly. A female bird, which 
I presume to be the same species, can scarcely be distinguished from 
1 Progne furcata. 
Progne furcata, Bairp, n. s. 
Hab. Chile (and other parts of western South America ?). 
(No. 9,112, §.) Color as in P. subis, with rather more of a purple gloss. 
Basal portion of the feathers in the anal region dark brownish, without trace 
of the whitish of P. subis. Tail deeply forked (for over an inch). 
Measurements: Total length, 8.30; wing, 5.80; jell 3.60; perpendicular 
depth of fork, 1.06; difference between primaries, 2.70; length of bill from 
forehead, .50, from nostril, .32; ss gape, .90; width, .60; tarsus, .60 ; middle 
toe and claw, .90; claw alone, .25; hind toe and claw, .51; claw alone, .24. 
This species is like P. subis, but differs appreciably from a large series of 
specimens in a considerably longer tail (3.60, instead of 3.40), and a-much 
deeper fork (1.08; instead of .75.) The bill is considerably narrower than the 
average of subis, though not more so than in one specimen (4,773) from the 
upper Missouri. The concealed portion of the feathers about the anal region 
is much darker than in subis. The size, except of tail, is about the same. 
This is probably the species to which Gray (Cat. Br. Mus.) refers as P. 
modesta (concolor), from Chile. The P. concolor, the synonyms of which I 
give below, is a very much smaller species, with the tail less forked than in 
subis, instead of much more so, and is probably peculiar to the Galapagos.
