342 A memoir on the Rats and Mice of India. [No. 4, 
hindfoot 13 in.” Two specimens received from the late Major Berd- 
more, of Schwe Gyen, on the Sitang river, which separates Pegu 
from Martaban. ‘The upper parts of this species are as brightly 
coloured as in the British Dormouse (Myoxus AVELLENARIUS), or 
scarcely less so. 
Mus NIVIVENTER, Hodgson, J. A. 8., V. 234; Ann. Mag. N. #7, 
XV. (1845), p. 267, a house Rat. Proportions and characters of the 
last [rattoides |, but tail rather shorter, and long piles of the pelage 
rarer. Size less. Above, blackish brown, shaded with rufous; below, 
entirely pure white, tail and all. Snout to vent 54 in. Kail 6 in. 
weight 4 to 5 oz., of rare occurrence in Nepal.* Col. Tytler ee 
two specimens in spirit from Masuri, which I have considered to be 
this, and have noticed in J. A. S., XXVIII. 295, as “a well marked 
species, rather larger than as originally described.” A male measur- 
ing 6 in. long, with tail 7 in., and hind-foot nearly 1§ in., female 
even larger or 7 in. long, with tail 73 in. Two specimens, from 
Landour, I have supposed to be of this race ; but they are very like 
M. RnvurEscens, only with coarser and sub-spinous fur of duller colour- 
ing, and the minute setz on the tail are dusky-brown.} 
Mus ropustunus, nobis, J. A. 8., XXVIII. 294; also M. Ruress- 
cENS, Gray (?), var ? ibid. ; and (1 te an M. RUFESCENS, auct. of 
Burma and Penang, auctorum: JZ. ratius, brown var, apud nos, J. 
A. S., XVII. 559 (?) perhaps also WL. Berdmorei, nobis, J. A. S., XX. 
173. The common Rat of Lower Pegu and the Tenasserim provin- 
es, taken about houses at night, but I think not a burrower. The 
description of M. RoBUSTULUS was taken from a particularly fine speci- 
men preserved in spirit; much like M. ruFusceEns, but the upper 
parts are darker and less rufescent, and the tail about equals the 
head and body in length. One example procured in the vicinity of 
Calcutta, or perhaps this should rather be regarded as a variety of 
M. RUFESCENS. 
* In J, A. 8. V. 234, it is thus described ** Above, saturate black-brown ; be- 
low, pure white, tail considerably longer than the body, and paled on the inferior 
surface.” 
+ “ Dark brown; the cutting teeth very narrow and slender; hind-feet slend- 
er, 1 in. Length ‘of. head and body, 64 in.” (Gray, in Cat. of Mr. Hodgson’s 
specimens), Probably, therefore, not the same as the above; the fore teeth of 
which are of the usual breadth, and the hind-foot measures 12 in. ( ,..,..... ?
