Habitat, City of Mexico! Type in my collection. 



Bemarlcs. — This species is of a smaller size, with a longer and 

 larger bill, and much darker coloration than the true R. satrapa. 

 It has also the crest conspicuously larger and rather brighter ; 

 and the yellow bordering the crest is clearer in color. 



I have no specimen of R. satrapa olivaceus with which to 

 make a comparison ; but Mr. Eidgway has kindly made it, and 

 sent me his observations as follows: "It is remarkable for its 

 very deep coloration, in which respects it far exceeds any speci- 

 men of R. satrapa olivaceus from the northwest coast (Oregon to 

 Sitka), with which I have been able to compare it. The loAver 

 parts are dull light grayish-brown, tinged Avith olive and buff.
