1. *Tarsiger elgonensis Sharpe (Elgon Black-tailed Tarsiger). 



(J 3, ? 1, Juv. o^ 1. Not a common species. They frequent the forest 

 undergrowth. 



This species can be readily distinguished from 7'. intensvs or T. orientulis 

 by the absence of any yellow on the tail feathers, by being generally more richly 

 coloured and having the white spot above and in front of the eye extending 

 almost from the nostril to the posterior angle of the eye. A point of great interest 

 is that the young of this species has yellow on the rcctrices, but it cUffers from 

 the young of closely allied species in being generally more buffy and spotted 

 on the underside, instead of being yellowsh or yellowish green and spotted.
