Adult Male. Similar to A. longuemarii, but differs in having a broad 

 band across the lower back and the whole of the least series of wing-coverts 

 metallic green ; tail more glossed with blue, and with partial white margins 

 to some of the outer feathers. Total length 4 - 9 inches, culmen 055, wing 

 2-55, tail 21, tarsus 07. Laga in Somaliland, 29. 11. 94 (F. Gillett). 



Adult Female. Like that of A. longuemarii, but the metallic shade of 

 the upper tail-coverts and tail is more blue than lilac ; the whitish edges to 

 the tail-feathers distinct, and the abdomen and under tail-coverts white like 

 the chest. Total length 4-6 inches, culmen 0-55, wing 2-4, tail 1-75, tarsus 

 0-7. Lado, 18. 4. 79 (Emin). 



Other adult males show that the green on the lower back is somewhat 

 variable in amount, and a few have a slight trace of violet on the innermost 

 least series of wing-coverts ; the partial whitish edges to several of the 

 outer tail-feathers is constant, regardless of sex or age, and is entirely 

 absent in A. longuemarii. 



The Eastern Violet-backed Sunbird probably ranges over 

 German East Africa generally, northward into Somaliland 

 and the Upper White Nile district. 



The most southern locality from whence I have seen this 

 species is Altoni, south-west of Zanzibar, where Emin pro- 

 cured an adult male which is now in the British Museum. To
