In the second group the rostrum is "shortened" (its length less than one third of greatest length of skull) and the cheek-teeth are of moderate to large size (M1 3.3-4.1 wide). _Pteropus rayneri_, endemic to the Solomons and represented there by at least seven subspecies, fits into this category. The third group is represented by _P. mahaganus_ and _P. woodfordi_. Both species are endemic to the Solomon Islands. In these species the rostrum is unshortened but the cheek-teeth are greatly reduced, especially in width (M1 is 1.0-2.2 wide). Both _P. mahaganus_ and _P. woodfordi_ can be included in the _Pteropus scapulatus_ group of Andersen (1912:402). =Pteropus hypomelanus= _Pteropus hypomelanus_ is a wide-ranging species of flying fox having at least seven subspecies; three occur in southeastern Asia, two on and near Celebes, and two in New Guinea and islands adjacent to the southeastern coast of New Guinea, including one island in the Solomons (Ellerman and Morrison-Scott, 1966:95; Laurie and Hill, 1954:32-33).

Hist., ser. 8, 2:362, October, type from Kiriwini Island, Trobriand Islands; 1912, Andersen, Catalogue of the Chiroptera ... British Museum, 1:128; 1947, Sanborn and Beecher, Jour. Mamm., 28:388, November 19, from Banika Island, Russell Islands. _Specimens examined._--None. _Remarks._--Andersen (1908:362) identified specimens of _Pteropus hypomelanus_ from eastern New Guinea and three nearby islands (Conflict Islands, Trobriand Islands, and Woodlark Island) as _P. hypomelanus luteus_. Sanborn and Beecher (1947:388) identified a female from Banika Island in the Solomons as of this subspecies although this specimen was darker and had a slightly smaller skull than typical _P. hypomelanus luteus_. They noted that the pelage of the venter of the female was uniformly dark rather than the typical Ochraceous-Buff to Cream-Buff; the specimen was regarded as a dark phase of the subspecies. Although not recorded previously for _luteus_, other subspecies of _P. hypomelanus_ were known in dark phase as well as pale and intermediate phases of coloration (Andersen, 1912:122). The reported occurrence of _P. h. luteus_ on Banika Island extended the known geographic range about 450 miles eastward from Woodlark Island. =Pteropus admiralitatum=
