670 BIEDS FROM MABGAIilTA—EOBINSOX. 



VOL. XVIII. 



[Tijpe.—^hxla adult, No. 151069, U.S.KM.; Margarita Island, July 

 5, 1895; Wilt Robiusou; collector's No. 432. Similar to B.fallax, but 

 luueli paler below, wliere pale buiiy fulvous; metallic greeu of upper 

 parts less brilliant and less brassy; size the same. Upper mandible 

 and tip of lower, black; lower mandible flesh color. Wing, 2.41; tail 

 (central feathers), 1.40; exposed culmen, 0,82 inches. 



Female adult, Xo. 151070, U.S.X.M.; Margarita Island, July 4, 1895; 

 same collector (No. 409). Does not differ from the male. Wing, 2.28; 

 tail (central feathers), 1.34; exposed culmen, 0.85 inches. 



Lieutenant Robinson collected over twenty specimens of this species, 

 which I have compared with three si)ecimens of B.fallax belonging to 

 the American Museum of Natural History and kindly loaned for that 

 purpose by Dr. J. A, Allen, They are uniformly paler than the three 

 examples of D.faUax, and all, without exception, have pale flesh-colored 

 lower mandibles, while those of D.fallax are apparently yellow when 

 fresh. At any rate, the American Museum specimens have the appear- 

 ance of having had yellow lower mandibles in life. There does not 

 appear to be any appreciable variation in the amount of white on the 

 outer tail feathers in D. XialUda, and the area occupied by white on 

 these feathers is the same in both species. 



In both forms the feathers of the under i)arts are edged with buff, the 

 less exposed part of the feathers being different shades of fulvous (light 

 in D. pallMa and darker in falJax), consequently, the more worn the 

 plumage, the darker the birds appear. The majority of specimens of 

 D. pallida are in somewhat worn plumage, while the three specimens 

 of B.fallax are in quite fresh condition, hence the differences between 

 the two species pointed out above will probably be greater when the 

 two birds are compared in the same condition of plumage. — C. W. E.]

ALICE'S 'HUMMING BIRD. 

 AmazUia allcicv, Richmond, Auk, XII, October. 1895, p. 3(38. 



The range of this brilliant humming bird is just the reverse of that 

 of the lueceding — that is, none at all were found in the coast region, 

 and only a few in El Valle; but in ascending the heavily wooded moun- 

 tains in rear, they became more abundant until when I had reached the 

 l^erpetual clouds that hung about the peak and entered an atmosphere 

 of mist, they were seen in all directions. The type si^ecimen, a finely 

 plumaged male, I shot from a mango tree as I sat in its shade drink- 

 ing the milk of a cocoanut. It fell within a few feet of me and was at 

 once seized hj a wandering chicken which made off" at full speed fol- 

 lowed by me in hot jiursuit. Fortunately there were no thorns to 

 impede me, and although I broke down a banana plant in my headlong 

 chase, I pressed the chicken so closely that it finally dropped my 

 prize.
