PROGNE CRYPTOLEUCA Baird. 

 CUBAN MARTIN. 



Adult male. — Exactly like P. suMs in coloration, except that the 

 feathers of the lower abdomen are always crossed by a broad but con- 

 cealed band of pure white; tail relatively longer and more deeply 

 forked, with lateral rectrices rather narrower terminally; length 

 (skins), 173-187 (180.1); wing, 140-145 (142.5); tail, 72-77 (74.2), forked 

 for 18-22.5 (20.4); exposed culmen, 10-12 (11.4); depth of bill at 

 frontal antise, 8-10 (9.5); tarsus, 12-16 (14.3); middle toe, 12-16 (14.3). « 



Adult female. — Very different from that of any of the forms of P. 

 subis, but very closely resembling that of P. dominicennix ; above dark 

 sooty brown, the feathers margined terminally (except on forehead 

 and anterior portion of crown) with dark steel blue, these glossy mar- 

 gins broadest on back and scapulars, where the underlying grayish 

 brown color is mostly concealed; wings and tail darker sooty brown 

 or blackish, faintly glossed with greenish blue; sides of head and neck, 

 chin, throat, chest, sides, axillars, and under wing-coverts uniform 

 grayish brown or deep sooty gray, similar to color of forehead, but 

 rather paler; breast, abdomen, anal region, and under tail-coverts 

 immaculate white, strongly and abruptly contrasted with the uniform 

 grayish brown or sooty gray color of chest and sides; length (skins), 

 172; wing, 140; tail, 67-69 (68), forked for 17-18 (17.5); exposed cul- 

 men, 10; width of bill at frontal antise, 9; tarsus, 6; middle toe, 16. 



Immature m.ale (second year). — Similar to the adult female in colora- 

 tion, but longer under tail-coverts with a central space of sooty gray, 

 and upper parts rather more strongly and more uniformly glossed 

 with steel blue. (Older individuals have the upper parts -nearly uni- 

 form dark violaceous steel blue, and scattered feathers of the same 

 color on the under parts, appearing first on throat and chest.)
