/j.C^6 RerI-EPSCII, De<icriftiov^ of Ne-,v Nrntrofircxl Birdi^. [October 



combining tlie large size of "the one form with the intense colors 

 of the other." This should be made out with a larger series of 

 skins, but I find that the plumage of the last-naaied bird is but 

 a little more reddish orange or fiery than in m^- specimen from 

 Tehuantepec. I nevertheless should remark that it has the bill 

 much more slender and rather more curved than in either of my 

 specimens from Tehuantepec and Guatemala, which possess 

 rather stronger and quite straight bills. 



My four skins from Yucatan in general agree verv well 

 among themselves regarding colors. One has the rump antl the 

 atxlomen slightly varied with a paler orange yellow, while 

 anotlier. which from its small measurements I regard to be an 

 adult female, diflers from the presumed males bv showing a 

 darker and less reddish orange color of the body, and has the 

 orange of tiie middle back (near the black mantle) soiled witli 

 ochraceous brown. 



I may add that in the new form the wings, bill, and legs (with 

 the claws also) are invariably shorter, but that the tail is quite 

 of the same length as \w\.\wq gul or is. Perhaps the white of the 

 inner webs of the quills is a little purer, and the black of the 

 thi^oat runs rather more to a point on the jugulum i^istead of 

 being rounded beneath.
