BIRDS — niEUNDINIDAE — HIEUNDO LUMIFEONS. 



.ao9 



The names both of Boddaert and Gmelin appear to have been based chiefly upon the HirondeUe 

 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 partSj not be the North American one, the next in order will be Barton's H. Twrreorum. 



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, (G-erman); the culmen, .18; the wings, 4.25; the tail, 2.6'7; 

 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.
