An adult female from Protrero, Cordova (IS^o. 41040, December 20, 

 1800, F. Snmiclirast), is essentially like the one described, but presents 

 the following slight differences: The loi) of the head is not nearly so 

 dark, scarcely ai>proa('hing black even on the longer feathers of the 

 crest, while, except these latter, the feathers have distinct but narrow 

 light brown shaft-streaks; the white streaks on cheeks and throat are 

 broader; the under parts are somewhat less richly colored, with the 

 white markings broader and less regular, while the rump and lower 

 back are more distinctly vermiculated and freckled with dusky. Wing, 

 5,50; tail, 2.05; exposed culmen, 0,75; depth of bill at base, 0,50; tar-

The seven specimens of 0.(/i(ttatus Gould with which these two Mexi- 

 can birds have been compared are all from Costa Rica, and all have 

 the bright ochraceons crest (overlaid by dusky), as shown in Gould's 

 plate. The l)irds described and figured by Gould are said to have come 

 from Honduras, The nuile rei)resented by him shows the conspicuous 

 ochraceons crest and agrees otherwise with the Costa Rica bird; but 

 the other ligure, representing what Gould says is the female, is with- 

 out any ochraceons, though not otherwise different; and he describes 

 the fenuile as different from the male " in having the crest of a uniform 

 brown, and in the black of the throat being less extensive," I am not, 

 however, inclined to credit the alleged sexual character of this dilfer- 

 ence in the color of the crest, since two of the seven Costa Rican speci- 

 mens (one of them, moreover, an immature bii'd) are umrked as females 

 by the collectors and have the crest colored exactly as in the males.
