BIRDS OF SOUTHERN VERACRUZ — WETMORE 233 



considerable material it appears to me that two races may be main- 

 tained. Anhinga anhinga anhinga (Linnaeus), marked by larger 

 size and broader tail tip, ranges from Venezuela and Ecuador to 

 Brazil, and presumably to Argentina. Anhinga anhinga leucogaster 

 (Vieillot), found from Colombia northward through Central Amer- 

 ica and Mexico to the southeastern United States, is slightly smaller. 

 The race Anhinga anhinga minima described by van Kossem from 

 the Pacific coast of Central America, from Nayarit to El Salvador, 

 I consider at present as of uncertain status. The type and some 

 others that I have seen are immature birds, as is the individual from 

 Langtry, Tex., called minima by van Rossem. Adults are appre- 

 ciably larger than immatures in this species, so much so that I am 

 doubtful whether this race can be recognized. This needs to be 

 settled definitely with adult material. The skin from Langtry, 

 Tex., I consider to be merely a young individual of leucogaster.
