116 MREUBIA VOIE. 
mouse-grey underfur becomes visible and there is some buff grizzling. The 
undersurface is a dull brownish grey grizzled with buff or dirty white. 
The fore and hind feet are clad with dark brown hair. 
_ The fur of young animals is much less coarse and shining and rather 
paler above. Below they are hair brown, markedly grizzled with whitish. 
The mammae are apparantly 3—3 = 12. 
Dr. DAMMERMAN has furnished me with a list of measurements of 
ten alcoholic specimens amongst which the following have a total length 
of over 500 mm. 
Head and body Tail 
Cheribon 305 mm. 249 mm. 
Plered 306 246 
Indramajoe 283 239 
Cheribon 207 240 
The skulls are interesting: even the smallest of those figured (Plate II) 
has the teeth worn and the basioccipital suture fairly closed: it is, however, 
very immature; but anyone unaccustomed to deal with these animals in 
sufficient numbers might quite possibly regard it as adult, even the medium- 
sized skulls illustrated, though perhaps adult, are by no means full grown 
as comparison with the largest skull show. All belong to the same form 
which is probably the Malaysian representative of, and subspecies of, 
Bandicota indica, (BECHSTEIN: syn. bandicota BECHSTEIN). 
For skull measurements see table p. 117. 
[The Buitenzorg Museum possesses a specimen of Rattus norvegicus from 
Palembang, Sumatra, It is a very abnormal individual and in colour bears 
an extraordinary resemblance to B. sefifera: but the fur of the upper parts, 
though very worn, is obviously shorter and less profuse. The under parts 
are almost as dark a brown as the back and are scarcely grizzled. 
The skull is that of a typical Rattus norvegicus as are the ears, feet 
and claws. The animal is adult with worn teeth and I have given its skull 
dimensions, for purpose of comparison, with the measurements of the 
skulls of Bandicota setifera.] 
Gunomys bengalensis sundavensis subsp. nov. (Plate Ill). 
Colour the same as in examples of G. b. bengalensis of similar size and age; and 
also apparantly the same as in G. varillus Thos. of Pemang '). Skull with rostrum 
lighter (less broad and deep). Incisors more projecting, not curved backwards as in 
b. bengalensis; molars larger, markedly broader, the first lamina of m! especially so. Mammae 
recorded as twelve in number; in b. bengalensis there are sixteen, 
Long bristles few and confined to the posterior back, 
General colour above a grizzle of dar brown and buff or ochraceous (the brown 
in excess) becoming on sides and lower parts mouse-grey grizzled with pale buff, the 
latter clearest and most marked on the throat and ventral area, the general effect 
otherwise being smoke-grey. Base of fur neutral grey. Feet dark, sides of hindfeet and 
the ankles paler. Tail finely scaled and indistinctly clad with very short hairs.
