12 HUMMING-BIRDS. 



[Case 14.] 

 HELIODOXA. " Brilliants." 



The tail is long and forked, the tarsi clothed with feathers, some to 

 the base of the toes : the bill is stent and about the same length as the 

 head. Four species are known, ranging from Costa Rica to Venezuela 

 and Colombia, and thence to Ecuador and Peru. 



[Case 14.] 

 CLYTOL^MA. " " Eubies." 



The sexes are different in colour. The tarsi only partly clothed or 

 booted, the tail being forked, and the bill stout, straight, and longer 

 than the head. The Eubies inhabit the lowlands of Brazil, Ecuador, 

 and Peru. Two species are known — C. ruhinea and C. aurescens. 



[Case 7.]* 

 EUGENES. « RivoLi." 



The bill straight, the wings long and pointed, and the tarsi clothed. 

 Two species have been described : — E. fulgens, which ranges from 

 Texas, through Mexico, to Guatemala ; and E. spedahilis, which re- 

 places it in Costa Rica. 



[Case 15.] 

 lONOL^MA. " GoKGETs." 



Four species have been described, of which the one exhibited, I. fron- 

 talis^ is the best known. They are all stoutly built birds, and are 

 readily recognized by their brilliant spots on the throat. The nostrils 

 are completely hidden by the feathers of the forehead, and the tail is 

 deeply forked. 



[Case 16.] 

 EUGENIA. "Empress Humming-Bied." 



Distinguished by its long and stout bill, its forked tail, the feathers 

 of which are stiffened, and by the feathering of the tarsi, which extends 

 nearly to the toes. The sexes are different, the female being more 

 plain than the gorgeously coloured male. The single species at present 

 known, Eugenia imperatrix, comes from the mountains of Ecuador, 

 where it is found at a height of from 6000 to 7000 feet. 



[Case 17.] 

 PTEROPHANES. " Sapphiee-wing." 



A very powerful bird, the largest, perhaps, of all the family, excejjt- 

 ing the Patagona gigas of Chili. The wings are very large and sickle-
