_Measurements of the holotype._--Length of head and body, 118; tail vertebrae, 23.0; hind foot, 16.0; ear, 14.0; length of forearm, 65.0; 2nd metacarpal, 33.2; 3rd metacarpal, 46.4; 4th metacarpal, 44.3; 5th metacarpal, 46.0; greatest length of skull, 32.4; condylobasal length, 30.6; palatal length, 13.0; breadth of braincase, 12.5; zygomatic breadth, 20.4; interorbital breadth, 5.5; breadth across first upper molars, 9.5; length of maxillary tooth-row, 10.5; length of mandibular tooth-row, 11.8. [Illustration: FIG. 15. Distribution of _Nyctimene malaitensis_ [BC] and _N. major scitulus_ [RW]. For names of islands see Fig. 2.] _Remarks._--In size, _Nyctimene malaitensis_ is intermediate between _N. albiventer_ and _N. major_. Because the type of _malaitensis_ is brown and not pale gray, as are females of _major_, _N. malaitensis_ most likely is more closely related to _N. albiventer_, in which the females are brown. The teeth of the holotype and only known specimen of _malaitensis_ are too worn to be useful in determining the relationships between these species. When more specimens are available, _N. malaitensis_ may prove to be a subspecies of _N. albiventer_. At present, _malaitensis_ is accorded specific rank in order not to obscure the apparent relationships of _N. albiventer bougainville_ and _N. a. minor_. Additionally, _N. malaitensis_ is given specific rank because (1) it is larger (especially in external dimensions) than the largest subspecies of _N. albiventer_ (compare above measurements with those in Table 3), and (2) _malaitensis_ does not form a cline with either of the two subspecies of _N. albiventer_. _Specimen examined_ (one female).--Malaita in July, 24103 (holotype). =Nyctimene major= This large species of tube-nosed bat has at least four subspecies, one of which (_N. major scitulus_) is endemic to the Solomons. The species occurs throughout eastern New Guinea and on many of the islands adjacent to the eastern coast of New Guinea, including the Trobriand Islands, the Bismarck Archipelago, and the Solomons (see Laurie and Hill, 1954:47). The geographic distribution of the species generally is the same as that of _N. albiventer_. In _Nyctimene major_, as in _N. albiventer_, most males are grayish-brown, whereas most females are pale gray. =Nyctimene major scitulus= Andersen 1910. _Nyctimene scitulus_ Andersen, Ann. Mag. Nat.
