BIRDS — IIIRUNDINIDAE — HIRUNDO LUNIFEONS. 



'M)\) 



The names both of Boddaert aiid (Iniolin ajipcar to liavc been based chiefl)' upon the Hirondelle 

 a ventre roux de Cayenne oi BulTon, PI. enl. 724, i'. 1, tlie 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 Jf. horreorum. 



Bnrmeister (Thiere Brasiliens, Viigel, II, 1856, 149) makes two species, retaining //. rvfa 

 for the South American one. He is mistaken in saying tlie Nortli American bird differs in 

 having the belly white, and the tail not so deeply forked. Tlie difference appears to lie in the 

 much larger size, and less uniformly rufous belly. According to Bnrmeister, the lengtli of a 

 Brazilian species is 5.00 inches, (German); the culmcn, .18; tlie wings,((t.25; the tail, 2.07; 

 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.
