 and Brazil (Para) ? '- 



« Three specimens. 



^One specimen. 



cSharpe and Wyatt, Mon. Hirund., 1894, 250. 



Regarding the alleged occurrence of this form in America I am inclined to believe, 

 without having seen the specimens upon which the records are based, however, that 

 the supposM examples of H. tytleri from Guatemala and Brazil are in reality dark- 

 colored specimens of H. erythrogastra. ( See remarks in footnote on p. 78. )
