1863. | A memoir on the Rats and Mice of India. B41 
M. flavescens et rufus, Elliot; M. arboreus, B. Ham., Horsfields, 
Catalogue, and figured by this name in one of B. Hamilton’s unpub- 
lished coloured drawings; (vide J. A. S., XX. 168) ; I. montanus, 
Kandianus, et tetragonurus, Kelaart J. A. S8., XX. 169,185. In 
general about 7 in. long, with tail 8 to 83 in. Colour rufescent, brown 
above, white or yellowish white beneath, mostly abruptly separated 
from the hue above, and rarely gradually blending. Inhabits per- 
haps all india, with Ceylon, also China ;* and as Mr. Hodgson could 
searcely but have met with it in the valley of Nepal, I take the 
following also to refer to it. 
Mus Caudatior, Hodgson ; described in Horsfield’s Catalogue of the Mamma- 
jia in the H. I. Museum, p. 144, “ Above, chesnut-brown with a rufous shade, 
more clear and passing into reddish on the rump; underneath from the chin to 
the vent, with interior of the thighs, white, with a very slight yellowish shade. 
Muzzle rather sharp, ears proportionally long. Body and head, 5% in. long; 
tail, in the prepared specimen, 6 in.” (A young individual?) “Tail exceeding 
the body in length,’ Hodgson, Ann. Mag. N. H., 2nd series, III. (1849) p. 203. 
The Mus PatMarvM, Scherzer, from the Nicobar islands, probably 
belongs to this group. 
M. cinnamomeus, Blyth, J. A. S., XXVIII. 294. “Like IL fla- 
vescens, but smaller, with proportionally longer tail and softer fur, 
of a fine bright cinnamon colour, with mconspicuous black tips, the 
under-parts white, which is abruptly divided from the cinnamon hue 
above. Length of head and body about 6 in., the tail 7 in., and 
The ball of the outer toes rather less than half the distance from the front of 
the foot. Inhabits India.’ Dimensions not stated. 
In the Brit. Mus. Cat. p, 109, specimens are recorded from Mexico and Bahia! 
Another is stated to have been received from India, on which the description 
was founded. 
Dr. Kelaart gives a Mus asraticus, Gray, with a note of doubt. ‘‘ Head and 
body (of a full grown enciente female) 6 in.; tail 5z in. Fur soft; above, pale 
brown mixed with black; sides, ashy-grey. Beneath, pure white, but not so 
defined as in MUs RUFESCENS (fiavescens, Wiliot) ; tail rather thin, shorter than the 
head and body. LHars large, slightly villous. Limbs slender. Geographical 
distribution, India, Ceylon.” 
In Dr. Kelaart’s Prodromus Faune Zeylanice we have Mus flavescens, Hlliot 
(syn. M. rufescens, Gray, and M. rufus, Elliot), with var. rufo flavescens (syn. VM. 
tetragonwrus, Kelaart); also var. Kandianus (syn. M. Kandiawus, Kelaart) ; and 
M. nemoralis, Blyth (erroneously described, syn. M. arboreuws ? apud Kelaart). 
Specimens of all these were received in the Society's Museum from Dr. Kelaart, 
and may he positively referred to M. RuFEScENS, Gray, (apud Gray). It is 
therefore useless to quote his descriptions ; but he also sent the true M. NEMoRA- 
Lis, nobis, of which I take his “small house Rat of Trimcomali” to be a half 
grown example. 
* We have a Chinese specimen, presented by R. Swinhoe, Esq.
