BIRDS—IIIRUNDINIDAE—HIRUNDO LUNIFRONS. 
309 
The names both of Boddaert and Gmelin appear to have been based chiefly upon the Hirondelle 
a ventre roux de Cayenne of Buffon, PI. enl. 724, f. 1, the former having priority. Should 
this species, therefore, as is probable from its much smaller size and more intensely rufous 
under parts, not be the North American one, the next in order will be Barton’s H. horreorum. 
Burmeister (Thiere Brasiliens, Vogel, II, 1856, 149) makes two species, retaining H. rufa 
for the South American one. He is mistaken in saying the North American bird differs in 
having the belly white, and the tail not so deeply forked. The difference appears to lie in the 
much larger size, and less uniformly rufous belly. According to Burmeister, the length of a 
Brazilian species is 5.66 inches, (German); the culmen, .18; the wings, 4.25; the tail, 2.67; 
differences readily appreciable. He gives H. americana, Gmelin, 1017, for the North American 
bird; but this cannot be the case, since this species is described as having a rufous rump and 
even tail; locality, the La Plata.
