Thirteen skins (five male and eight female), besides four alcoholic 

 specimens, agree in the possession, to a greater or less extent, of the 

 characters which separate this bird from its mainland representative 

 (C dnbiufi), of which about a dozen specimens have been compared with 

 the Cozumel series. In G. dtibius the upper tail coverts and lower part 

 of the rumj) are invariably immaculate white, and the lower parts a 

 rather light olive-gray. In C. leei, three of the five males and five out 

 •of eight females have both the lower rump and the upper tail-coverts 

 decidedly varied (usually barred) with black, while the exceptional 

 specimens have only the longer upper tail-coverts immaculate, and 

 these usually with black shafts or other concealed markings. The lower 

 parts are in every instance decidedly darker than in the mainland bird, 

 the red of rhe abdomen also being much more intense.
