306 REVIEW OF AMERICAN BIRDS. [PART I. 
genus among American Swallows. In two specimens before me I 
can make out only ten tail feathers, and cannot say whether more 
exist. Neither has the wings perfect, so that I cannot indicate the 
number of primaries. The type, and hitherto single representative 
of the section, is A. fasciata, of Cayenne.* 
NovTmocHELIDON, Baird. 
Notiochelidon, Bairp. (Type Atticora pileata, Goutp.) 
Bill small; nostrils superior, as in Afticora, but less perfectly circular. 
Tarsi entirely bare, even on the joint of tibia, rather long-—equal to middle 
toe and half claw. Lateral toes short; about equal, or the outer a little the 
longer; the claws all stout, sharp, much curved. Outer toe adherent for 
nearly half its length (two terminal joints free) ; the terminal one and a half 
joints, or three-fifths of middle toe free. Inner toe united to basal two-thirds 
of middle. Tail deeply forked for about one-third the length, the branches 
divaricated. 
No metallic lustre, except upon the top of head. Beneath white; the 
erissum blackish. 
This form differs from typical Até¢cora in less deeply forked tail, 
and in less adhesion of toes—the middle toe being free externally 
for one and a half joints, instead of only one, and internally in pro- 
portion. The feet are more slender, and the claws less curved; the 
tarsus entirely bare, even to the joint.
