XL.— On a new African Species of the Genus Zosterops. 
By Th. von Heuglin*. 
(Plate XIII.) 
The genus Zostei'ops (a very circumscribed and very distinct one, 
though not very rich in species) is found over nearly the whole of 
Africa, in Madagascar, Australia, some parts of Northern Asia, 
and in the Southern Indian Islands. 1 discovered a new species 
in the high mountainous districts of Abyssinia, easily to be 
distinguished by its very large eyes and eye-rings, and by its 
breast and upper abdomen being of a pure grey. In my “ List 
of N.E. African Birds/' printed in the € Transactions of the 
Vienna Academy,' I have enumerated this new species under 
the name of Z. euryophthalma , but now I prefer changing this 
name into 
Zosterops poliogastra. (PI. XIII.)

The male is a little more brightly coloured than the female. 
The first primary is 2' 7 shorter than the second, third, and fourth, 
which are the longest. This pretty species lives on the high¬ 
lands of Abyssinia; I found it there in the month of February 
and March in wooded districts, on Euphorbice and olive-trees, at 
an elevation of 10-11,000 feet.
