from Deyra Doon,” also described from a specimen in spirit belong-

Mus sactrianus, Blyth, J. 4d. 8S. XV. 140. “ Presents a very 
close approximation to M. MuscuLUs in size, proportions and 
structure, inclusive of the conformation of the skull; but the fur is 
much denser and longer, and its colouring absolutely resembles that 
of a pale specimen of GERBILLUS INDICUS, except that there is no 
whitish about the eyes, nor is the crown of a deeper hue, and the tail 
is thinly clad with short pale hairs to the end.* * * The entire un- 
der parts and feet are white; and the upper-parts light isabelline, 
with dusky extreme tips to the hairs, and their basal two-thirds deep 
ashy.”’ (B.) :—The common house Mouse of Kandahar ; but the house 
Rat is, I believe, unknown there: at least so all my informants agreed 
in stating, and I certainly never saw one, although for two years I 
was in charge of extensive grain godowns, which would naturally have 
attracted them had any existed.” (Hutton.) Syn? JW. gerbillinus, 
nobis, J. A. S. XXII, 410, and MW. TVheobaldi, nobis, J. A. V, 
XXII. 583.

the colour of the back. About twenty-five caudal vertebre. ‘Tail

M. nitipunus, Blyth, J. A. S. XXVIII. 294. “A house mouse 
apparently, with tail equal to the head and body, and uniformly 
furnished with minute setz to the end; ears large and ample. To- 
tal length 6% in.; hind-feet a little exceeding # in.; and ears (poste- 
riorly) .®; in. Colour nearly that of M. prcumanvs, with the under 
parts subdued white tolerably well defined. Of the same subgroup 
as M. muscunus* and M. urpanus,” but with the front-teeth con- 
spicuously larger. Received from Schwe Gyen, on the Sitang river.
