312 Mr. Boyd Alexander on the 



d. Imm.? <S (with metallic throat). Basakato, Nov. 12, 

 1902. 



According to my note-Look, this last specimen had the 

 breeding-organs largely developed, and therefore could 

 hardly be an immature bird. With the exception of the 

 metallic coloration on the throat, fore-neck, and forehead, 

 it is in the plumage of the adult female. The upper parts 

 are much worn and bleached. This, I think, proves that 

 the male assumes the female plumage at one season of the 

 year (probably during the rains).

Near Bakaki, 4000 feet, Nov. 20, 1902. 



We obtained two specimens, both males, of this rare little 

 Sun-bird, which frequented the low bushes on the steep 

 ascents of the mountain. It is a quiet bird and seems fond 

 of solitude. 



It is named after the author's niece, Miss Ursula Davis.
