BIRDS OF NORTH ANB MIDDLE AMERICA. 633 



eameus approaches the South American C. phosniceus, notably in the 

 shape of the bill, its long, stiff crest-feathers, the light-reddish rump 

 of the male, and absence of red on the outer surface of the wing in 

 the female. C. phoeniceus, however, as might be expected from its 

 isolation, is very distinct indeed from all the rest. With a general 

 resemblance to C. cardinalis (including its various forms) and C. 

 carnms, the bill, in both sexes, is grayish instead of bright red; the 

 black capistrum is far less extensive, being restricted to the chin; and 

 the female has the under wing-coverts pale buffy instead of bright 

 pinkish red. The form of the bill is also quite different, being almost 

 intermediate between that of O. cardinalis and that of PyrrhuHoxia 

 sinuata.
