Of the 85 species of Zosterops mentioned by Gadow, 61 are 
restricted to special localities, and of these 58 to special islands 
orisland groups. This genus traverses Africa from the west 
(islands in the Bay of Biafra) to the east (Abyssinia and Soco- 
tra). It is found on all the islands on the southeast coast of 
Africa, Madagascar, Comoro Islands, Grand Comoro, Island of 
Mayotte, Glorioso Islands, the Mascarenian Islands, Bourbon 
and Mauritius, Aldabra and the Seychelles. The next localities 
eastwards are the Laccadives, Ceylon, the whole of India with 
the Himalayas ; then follow the Burmese countries to south- 
“ Gadow believes that all the specimens from these localities belong to Z. pal- 
pebrosa Temm. It would be strange if this species is different from the others, 
which have often very restricted localities.
