ODONTOPHORUS GUJANENSIS MARMORATUS (Gould) 



Maebled Wood Quail 



Adult. — Similar to that of the same sex of Odontophorus gujanensis 

 castigatus but with the interscapulars and upper back definitely black and 

 gray, not brown, distinctly different from the rest of the upperparts; 

 the crest much darker, the longer, posterior plumes blackish, marginally 

 and basally flecked with cinnamon-brown ; general tone of the upperparts 

 darker; feathers of back, rump, and upper tail coverts more uniform, 

 less flecked and vermiculated with blackish ; upper throat with more white 

 in the pale cross bars; abdomen, sides, and flanks more conspicuously 

 barred with pale cinnamon-tawny edged with blackish. 



In some specimens the chin and throat are marked with white; this 

 appears to be an individual variation of no geographic or racial significance. 



Adult male.— Wing 134.5-154.5 (143.1) ; tail 63.5-77.5 (68.8) ; culmen 

 from base 18.9-21.9 (20.4) ; tarsus 43.2^7.5 (45.1) ; middle toe without 

 claw 32.3-37.5 (35.7 mm.).^^ 



' Seventeen specimens from Panama and Colombia.
