 spots to the primaries as in the adult male and is very similar to 

 adult specimens, hut somewhat paler and less distinctly marked.

Adidt male. Top of the head brownish grey, streaked with 

 bi'ownish black along the middle ; a rusty collar round the neck, 

 very conspicuous above, slightly indicated below ; back and rump 

 greyish brown with dark longitudinal streaks ; scapulars with large 

 brownish-black patches and others of a pure rustj^-bufif colour ; 

 wing-coverts with smaller and paler buff spots ; primaries deep 

 brown, washed with greyish near the tip ; tirst primary with some 

 smaU fulvous spots near the tip of the outer web and a small rusty 

 spot on the inner web ; second, third, and fourth with a white band 

 across both webs, the band interrupted on the second ; all the other 

 quills brown banded with rufous ; two outermost rectrices white for 

 their whole length, with a long brown streak and a huffy shade on the 

 outer web, a narrow space at the base brown ; two white spots on 

 the throat ; abdomen buff, barred with brown. Total length about 

 9 inches, wing 6, tail 4-7, tarsus 0-65. 



The female is said by Heuglin to be smaller. 



A quite young male shot by Mr. F. J. Jackson on ilt. Elgon un- 

 doubtedly belongs to this species, as the white marks on the 

 primaries and rectrices clearly indicate. The outer rectrices are 

 much mixed with brown on the outer webs, the feathers of the 

 upper surface have bright rufous terminal spots, and the abdomen is 

 indistinctly barred. 



This species may be distinguished from all other African Goat- 

 suckers by having the two outer pairs of tail-feathers almost 

 entirely white : they are only white to a considerable extent in the 

 very diiSerent C. natalensis from South Africa. 



The description is taken from the type in the museum at Frankfort. 



Hab. Eastern and Central Abyssinia and Galla district from the 

 valley up to about 12,000 feet above the sea-level south to Mt. 

 Elgon.
