Of the seventeen species of Aplonis only one, A. cantor Müll., 
has a more extensive distribution. It extends from Mysol, 
Salavati, Batanta, small islands at the west end of New Guinea, 
through New Guinea and the Louisiade Islands, and from the 
Admiralty Islands, New Britain and Duke of York Island to 
the Solomon Islands. A. fuscus Gould, occurs on Norfolk and 
Lord Howe’s Island. The other fifteen species are restricted 
to special localities: Tenimber Islands; Fead Island; New 
Hebrides ; Loyalty Islands; New Caledonia, with Isle of Pines; 
Fiji Islands and Rotumah Island; Tonga Islands; Fortuna 
Island; Savage Island; two Samoan Islands; Rarotonga Is- 
land; Raiatea, Society Islands; Carolines: Ponapé, Kuschai, 
Ruk and Lugunor; Interior mountains of Ponapé. 
The genus Erythrura Swainson, also shows a very interest- 
ing distribution; Æ. prasina Sparrm., is found from southern 
Tenasserim, down the Malayan Peninsula to Sumatra, Java 
and Borneo; E. trichroa Kittl., on the Moluccas, New Guinea, 
Carolines and Solomon lands, E. cyaneifrons E. L. Layard, 
on the Loyalty Islands and the New Hebrides. The remain- 
ing eight species have special localities: Tenimber Islands; 
Timor; New Caledonia; Island of Aneitum, New Hebrides ; 
Island of Api, New Hebrides ; Rewa, Taviuni, Fiji Islands; 
Viti Levu, Fiji Islands; Sumos Telande. 
The peculiar differentiation of Aplonis and Erythrura on 
the different groups of islands can only be explained by their 
continental origin.
