the female of dominicensis, except in the brownish shafts of the 
longer crissal feathers, and an almost imperceptible tinge of brown- 
ish in the webs of the same feathers. It is almost exactly like the P. 
leucogaster, of Mexico and Central America. 
A fuller series of specimens than is at present at my command 
will be required to determine all the relationships of this species to 
its allies. 
A Progne, male (10,368), of the second year, from Cape Florida, 
I somewhat hesitatingly refer to the same species, as having the 
same proportions and dimensions. This is the specimen referred to 
in the Smithsonian Catalogue, and Birds N. Am. 923,as Progne :

(No. 30,278, adult male, Jamaica.) General color lustrous steel blue, with 
purplish reflections ; the median region only of the under parts, from the 
breast to and including crissum, pure white. Feathers of tibia gray at base, 
white at tip. Wings and tail blackish above, scarcely glossed, except on 
lesser and middle coverts. A concealed white streak in the sides, hidden by 
the wing—this color at the base of the feathers, and not extending to the 
ends. Bill black; feet dusky, perhaps dark flesh-color in life. “Iris hazel” 
( Gosse). 
(No. 26,815, female.) Much duller in plumage. Above dark brown, or 
smoky brown, glossed with dull steel blue ; the quills, rectrices and head brown, 
almost without gloss. Sides of head neck and body, chin, throat, jugulum, 
and inside of wings dull wood brown, without gloss; the median line of chin 
and throat rather paler; rest of under parts white, as in male, and quite 
abruptly defined ; tibia gray, the feathers tipped with whitish. 
The young male is like the female, with more steel blue on the head, the 
throat with blue feathers interspersed. Very young birds are like the female, 
and exhibit the same quite abruptly defined white below, with well marked
