[Illustration: FIG. 8. Greatest length of skull plotted against zygomatic breadth for two subspecies of _Dobsonia inermis_. Symbols represent _D. i. inermis_ ([BW]), _D. i. minimus_ ([TW]), and intergrades assigned to _minimus_ ([BC]). Capital letters are used to relate groups of specimens to the island or islands from which they were collected; spatial distribution of specimens indicated in the scatter diagram thus is shown in the inset map. Specimens from Santa Ysabel and Bougainville are deposited in the Australian Museum. The type specimen of _D. i. inermis_ is labeled "E." For names of islands see Fig. 2.] [Illustration: FIG. 9. Distribution of _Dobsonia inermis inermis_ ([BC]) and _D. inermis minimus_ ([RW]). For names of islands see Fig. 2.] TABLE 2.
