324 ZOOLOGICAL BESULTS OF THE EUWENZOBI EXPEDITION. 



Young males have the crown, chin, and throat blackish, usually with a few metallic 

 feathers, the mantle olive, without the orange wash found in the adult, and the 

 breast and rest of the underparts greyish, washed with olive. 



[Jackson's Purple-throated Sun-bird was found on Ruwenzori at elevations of from 

 5500 to 8500 ft. It was plentiful both in the forest and below it, feeding largely 

 upon the scarlet flowers of Erythrina tomentosa. Females of this species were 

 remarkably difficult to obtain ; when numbers of these birds were feeding in the 

 same tree the proportion of males to females was always as great as eight to one. 

 This was the case during the whole time we remained in the mountains, so that the 

 possible explanation that most of the females were engaged in incubation would not 

 hold good.— B. B. W.]

Adult male and female. Iris dark brown; bill and feet black. 



All the above-mentioned specimens belong to the larger form of C. acik Antinori, 

 which has been separated by Dr. Reichenow under the above name. The latter states 

 that the metallic green of the top of the head and chin is of a different colour in the 

 two forms; but this does not appear to be really the case. The only real difference 

 seems to be one of size, the more northern C. acik being altogether smaller and having 

 a much shorter bill.

Mr. G. Archer notes that he did not meet with this species on Ruwenzori, though 

 he procured specimens in Toro.
