_Diagnosis._--Small for _Nyctimene_; wing membranes brown with scattered yellow spots (dried specimens); uropatagium, feet, and ears brown; dorsum of tibia set with hair, ventral surface naked; dorsum of uropatagium sparsely set with pale brown hairs, ventral surface almost bare; fringe of hairs along two centimeters of dorsal and ventral surfaces of trailing edge of wing membrane; proximal third of dorsal surface of forearm sparsely set with hairs; pelage of back soft and thick, of medium length (about 7); hair on crown and nape short (about 4); well-defined black dorsal stripe, extending from uropatagium to shoulders; skull resembling that of other subspecies of _N. albiventer_ but relatively smaller; zygomatic arch delicate, slender anteriorly; P2 small (see Fig. 14). Sexually dichromatic as follows: male--dorsum Hair-Brown, bases of hairs darker; hair on throat sparse, medium length (about 6), Hair-Brown; fur along sides of abdomen Drab; female--dorsum having Buffy-Brown cast, some individual hairs Hair-Brown; shoulders Sayal-Brown; hair on throat sparse, Hair-Brown on throat and midline of abdomen; sides of abdomen Sayal-Brown. _Comparisons._--From _Nyctimene major scitulus_, the largest member of this genus in the Solomons, _N. a. minor_ differs in being smaller in all measurements taken; forearm averaging 54.8 as opposed to 73.5; greatest length of skull 28.2 as opposed to 37.0, and females pale brown instead of pale gray. From nine adults of _Nyctimene albiventer bougainville_ from Bougainville, Kolombangara, and Guadalcanal, _minor_ differs as follows: averaging slightly smaller in all dimensions; forearm averaging 54.8 as opposed to 57.9; second metacarpal averaging 27.4 as opposed to 28.3; 5th metacarpal averaging 38.5 as opposed to 40.0; condylobasal length 26.7 as opposed to 28.0; length of mandibular tooth-row 10.3 as opposed to 10.9; mandible smaller (see Fig. 14); dorsal stripe fainter. From _Nyctimene albiventer papuanus_, known from eastern New Guinea, New Britain, and the Admiralty Islands, _minor_ differs as follows: slightly smaller in most dimensions; forearm averaging 54.8 as opposed to 57.0; length of maxillary tooth-row 8.9 as opposed to 9.8; length of mandibular tooth-row 10.3 as opposed to 11.0; breadth across upper third premolars notably less (7.5 as opposed to 8.4). _N. a. minor_ differs from _N. albiventer albiventer_ Gray, which occurs about 800 miles to the west of _minor_, in ways made apparent by the description by Andersen (1912:700-701). _N. a. minor_ occurs about 1500 miles eastward of the place from which _N. a. draconilla_ Thomas, a subspecies essentially unknown to me, was named (see Laurie and Hill, 1954:46). From _Nyctimene sanctacrucis_, known from the Santa Cruz Islands, _minor_ differs as follows: much smaller in all dimensions; forearm averaging 54.8 as opposed to 75; greatest length of skull 28.2 as opposed to 34.5; length of maxillary tooth-row 8.9 as opposed to 12.9.
