Andersen is now inclined to regard intermedius as only a sub- 
species of vampyrus (P. Z. 8. 1916, p. 40) and if this is right we 
cannot expect to find it in areas occupied by malaccensis ; so it 
looks as though the type locality of intermedius (Amherst, near 
Moulmein) is near the southern extremity of its range, which may 
stretch northwards through Burma towards Assam _ where 
P. leucocephalus Hodgs. occurs.

The two adults have the breast and the 
grizzled throughout; the back blackish grizzled with silvery; and 
the head as far as the ears about auburn, becoming black on the 
cheeks and throat. Dr. Smith’s specimen has the mantle buffy, the 
anterior sides of neck and a median area on the foreneck tinged 
with Sudan brown. Mr. Webb’s female has the mantle and neck 
Sudan brown suffused with auburn brown in front. |The immature 
male has the back as in the adults, the head Sudan brown blending 
with a buffy mantle and the sides and front of the neck suffused 
with amber brown; the throat is black; the hairs of breast and 
belly are blackish at base with ochraceous tips, the ventral area 
alone being dark brown; this young animal (skull, 58.5; forearm, 
138 mm) resembles specimens of DP. giganteus (Brunn.). 
Pteropus lylet does not appear to develop a sagittal crest. 
The two larger specimens are quite adult with the teeth worn and 
the basioccipital suture completely obliterated, but the ridges on the 
cranium are 4-5 mm apart,
