the female of dominicensis, except in tlie brownish shafts of the 

 longer crissal feathers, and an almost imperceptible triige of brown- 

 ish in the webs of the same feathers. It is almost exactly like the P. 

 leucogader, 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 .

Hirundo albiventris, Vieill. Nout. Diet. XIV, 1817, 533 (St. Domingo?). 



Hah. Jamaica, Porto Rico, and St. Domingo ? 



(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
