In coloration and most cranial dimensions the specimens listed above agree with specimens of _D. i. inermis_ from Alu, Shortland, and Rubiana (Andersen, 1909_c_:532; 1912:475, 476), Bougainville (Troughton, 1936:348, 349), and Rennell (Hill, 1963:74). The forearm in the adult male holotype of "_nesea_," from Shortland, is 109.5 as opposed to 109.0 in an adult female topotype of _inermis_ from Ugi (Andersen, 1912:478) in the southeastern part of the archipelago (see Fig. 9). Forearms of specimens of _D. i. inermis_ from Vella Lavella are 107 to 112 (measurements from labels because forearms of these specimens were broken and therefore could not be remeasured). Forearms of specimens from Fauro, Florida, Guadalcanal, and Rennell are 103.6 to 110.0 (see Hill, 1956:74). Variation in length of forearm probably is not significant because no cline is evident (see Fig. 9 and Table 2). In 1964, 11 specimens of _Dobsonia inermis_ were collected on Choiseul. They are smaller, externally and cranially, than specimens of _D. inermis_ from Sun Cristobal, Ugi, Rennell, Guadalcanal, Florida, Rubiana, Vella Lavella, Shortland, Alu, Bougainville, and Fauro, and may be named and described as follows: =Dobsonia inermis minimus=, new subspecies _Type._--Adult male skin and skull, in good condition (originally stored in 70 per cent alcohol for about one year), no. BBM-BSIP 23716, Bernice P. Bishop Museum; from Choiseul Island, British Solomon Islands Protectorate; obtained on 20 March 1964 by Philip Temple, original number 1524. _Distribution._--Choiseul Island (type locality); intergrades from Santa Ysabel also assigned to this subspecies. _Diagnosis._--Size small for species; wing membranes, feet, and ears black; dorsal surface of interfemoral membrane sparsely set with silvery hairs, other membranes naked; hair soft, medium length (10 on mantle, 5 on crown), black hairs and scattered white hairs on face and crown; fur of dorsal surface of mantle composed of whitish hairs having faint olive cast imparting general color of Buffy-Citrine; hair of venter short (about 5), soft, and fine; general coloration Buffy-Citrine; cranium delicate; rostrum narrow in dorsal aspect (nasals not expanded laterally); forehead (junction of nasals and frontals) pronounced in lateral aspect; teeth resembling those of other subspecies of _D. inermis_ but slightly smaller. _Comparisons._--From adults of _Dobsonia inermis inermis_, which occurs on Rennell, San Cristobal, Ugi, Malaita, Florida, Guadalcanal, Rubiana, Vella Lavella, Shortland, Alu, Bougainville, and Fauro, _minimus_ differs in being smaller. Average length of mandible 31.2 and 33.4. For other measurements see Table 2. From _Dobsonia praedatrix_, which occurs on New Britain, New Ireland, and Duke of York (northward of the Solomons), _minimus_ differs in being smaller in all dimensions; length of forearm averaging 100.5 as opposed to 116.0, and greatest length of skull 42.4 as opposed to 50.0.
