AMAZONA ALBIFRONS NANA Miller. 



LESSER WHITE-FRONTED PARROT. 



Similar in coloration to A. a. albifrons but decidedly smaller. 



Adult male.— Length (skins), 220-280 (246); wing, 157.5-180 

 (166.5); tail, 73-87.5 (79.6); culmen, 23.5-28 (25.4); tarsus, 17-20 

 (18.4); outer anterior toe, 22-26.5 (23.9). 6 



° I can not appreciate any constant differences of coloration, though many speci- 

 mens, especially among those from western Nicaragua and Costa Rica (the species 

 apparently does not occur on the Atlantic side of those countries) have the throat 

 more or less (sometimes, conspicuously) intermixed with red. 



6 Nineteen specimens.
