from Z. flavilateralis by the darker olive-colour of the upper- 

 parts -which are tinged ^vith greyish, the narrower yellow 

 frontal band and the paler yellow underparts. A series of 

 specimens shows that there is no difference in size, as indi- 

 cated by Reichenow [Vog. Afr. iii. p. 429 (1905)]. The 

 specimens procured by Dr. Donaldson Smith at the Sillul 

 River in Ogaden, Somaliland, were identified by Sharpe as 

 Z. flivUateraUs and afterwards described by Prof. Neumann 

 as Z. smifhi. They appear to be identical with Z. jubaensis. 



As regards Zosterops tenella Hartl. from Abyssinia, I 

 cannot see that this bird is separable from specimens from 

 Nyasaland and Mashonaland, which have been referred by 

 Shelley to his Z. anderssoni, the tvpe of which came from 

 Elephant ^'ley, Damaraland. The Daraaraland birds, though 

 closely allied to Mashona and Nyasaland specimens, lack the 

 distinct yellow hand across the lores to the eye contrasting 

 strongly with the olive plumage of the rest of the head. In 

 Z. anderssoni, the "yellow forehead, lores and ocular region 

 shade imperceptibly into the yellowish-olive crown. 



Both these birds are subspecies of Z. senegalensis, Bonap. 

 which ranges from Gambia to the Bahr-el-Gazal and south- 

 wards to Kavirondo. In the Jackson collection there are 

 two specimens with a wing-measurement of 55 mm., which 

 appear to be referable to this smaller western form.

Zosterops virens kajfensis Neumann, J. f. O. 1906, 

 p. 243. 



A large series of the Kaifa White-eye seems to differ con- 

 stantly from Z. V. schoana Neumann, Z. v.jaclsoni Neumann, 

 and Z. V. kikuyuensis Sharpe, and bears out the characters 

 pointed out by its original describer. The yellow on the 

 forehead does not extend beyond a line drawn between the 

 eyes. Specimens were obtained about the Gebbe and 

 Didessa Rivers, also in Gomma, Jimma and Kaffa, where it 

 was common. 



This White-eye was not previously represented in the 

 British ^luseum.
