AduU male. Eesembles C. 'principalis in having white nasal tufts 

 and a white neck-stripe, but differs in the latter being continued to 

 the base of the bill ; the black feathers of the crown not reaching 

 to the tip of the scarlet crest. 



AduJt female. Differs from the adult male in having the crest 

 entirely glossy blue-black. 



Never having seen this species, I have extracted the above 

 descriptions from Eidgway's Manual. The measurements are given as 

 follows:-— \ying9-50-9- 70, tail 6-50-7-00, exposed culmen 2-30-2-40. 

 Cassin, in his original description of the i)resent bird, states the length 

 to be about 18^ inches. This author's observation that the black 

 anterior feathers of the crest are longer than those succeeding, which 

 are scarlet, is, however, at variance with Dr. llidgway's statement.
