Returning to the Papuan lands proper, in the insular groups west of New Guinea we enter one of the most entangled ethnical regions in the world. Here are, no doubt, a few islands such as the Aru group, mainly inhabited by full-blood Papuans, men who furnished Wallace with the models on which he built up his true Papuan type, which has since been vainly assailed by so many later observers. But in others--Ceram, Buru, Timor, and so on to Flores--diverse ethnical and linguistic elements are intermingled in almost hopeless confusion. Discarding the term "Alfuro" as of no ethnical value[337], we find the whole area west to about 120 deg. E. longitude[338] occupied in varying proportions by pure and mixed representatives of three distinct stocks: Negro (Papuans), Mongoloid (Malayans), and Caucasic (Indonesians). From the data supplied by Crawfurd, Wallace, Forbes, Ten Kate and other trustworthy observers, I have constructed the subjoined table, in which the east Malaysian islands are disposed according to the constituent elements of their inhabitants[339]: _Aru Group_--True Papuans dominant; Indonesians (Korongoei) in the interior. _Kei Group_--Malayans; Indonesians; Papuan strain everywhere. _Timor; Wetta; Timor Laut_--Mixed Papuans, Malayans and Indonesians; no pure type anywhere. _Serwatti Group_--Malayans with slight trace of black blood (Papuan or Negrito). _Roti and Sumba_--Malayans. _Savu_--Indonesians. _Flores; Solor; Adonera; Lomblen; Pantar; Allor_--Papuans pure or mixed dominant; Malayans in the coast towns. _Buru_--Malayans on coast; reputed Papuans, but more probably Indonesians in interior. _Ceram_--Malayans on coast; mixed Malayo-Papuans inland. _Amboina; Banda_--Malayans; Dutch-Malay half-breeds ("Perkeniers"). _Goram_--Malayans with slight Papuan strain. _Matabello; Tior; Nuso Telo; Tionfoloka_--Papuans with Malayan admixture. _Misol_--Malayo-Papuans on coast; Papuans inland. _Tidor; Ternate; Sulla; Makian_--Malayans. _Batjan_--Malayans; Indonesians. _Gilolo_--Mixed Papuans; Indonesians in the north. _Waigiu; Salwatti; Batanta_--Malayans on the coast; Papuans inland.
