The specimens collected by Dr. Kidder seem to agree better with cliri/solopha than 

 with chrijsocomc, in the lighter and more bluish shade of the upper parts, weaker bill 

 and general elongation of the coronal feathers ; although the yellow plumes on each 

 side of the head are neither so long nor so brightly colored as in the Philadelphia 

 Academy's specimen, upon which my actual knowledge of chrijsolopha rests. I aiu still 

 of opinion that diCticulty will bo fouud iu establishing the supi^osed sx)ecies upon a sat- 

 isfactory basis. — C.
