of dusky blackish along the upper edge of the cheek ; cheeks and 

 under surface of body bright pale yellow ; sides of body, tianks, 

 and thighs yellowish olive ; axillaries and under wing-coverts very 

 pale yellow ; quills dusky brown below, ashy white along the edge 

 of the inner web. Total length 4-S inches, culmen 0-5, wing 2-4:, 

 tail 2-15, tarsus 0'65. 



Mexican specimens are remarkable for their grey backs and 

 yellow crowns, very few examples showing more than a subterminal 

 indication of chestnut on the crest-feathers. Specimens from 

 Yeragua, in the 8alvin-and-Godman collection, are not only much 

 greener above, but one adult bird has the crown orange- chestnut 

 with ashy-olive tips to the feathers. Costa-Rican examples, how- 

 ever, are strictly intermediate, being a little greener than Mexican 

 ones, and having the crown more chestnut, with olive-yellow tips to 

 the feathers ; these tips may be only an indication of winter plumage.
