i_; _Mus
Bactrianus_; _Mus cervicolor_(?)--_Jerdon's Nos. 187, 189, 190, 191,
and 192_. These are all hill mice, except the last, and found under
the same conditions.

NO. 356. MUS HOMOURUS.

HABITAT.--Lower Himalayan range.

DESCRIPTION.--Dark rufescent above, rufescent white below; hands
and feet fleshy white; tail equal to length of head and body; "fur
more gerbille-like in character than in _M. musculus_" (or
_urbanus_), stated to be the common house mouse of the Himalayan hill
stations from the Punjab to Darjeeling. Stated by Hodgson to have
eight teats only in the female, other mice having ten. Possibly his
description was founded on young specimens. I myself was of opinion
for some time that I had got two species of hill mice, a larger and
a smaller, the latter being so much darker in colour, but I kept them
till the young ones attained full size in six months, at which time
they were not distinguishable from the old ones. Hodgson may have
overlooked the pectoral mammae when he noted the number.

SIZE.--Head and body, 3-1/2 inches; tail, 3-1/2 inches.

NO. 357. MUS DARJEELINGENSIS.

DESCRIPTION.--Dusky brown, with a slight chestnut reflection;
under-parts pale yellowish-white.

SIZE.--Head and body, 3 inches; tail, 2-1/2 inches.

NO. 358. MUS TYTLERI.

HABITAT.--Dehra Doon.

DESCRIPTION.--Fur long and full, pale, sandy mouse-coloured above,
isabelline below; pale on the well-clad limbs, and also on the tail
laterally and underneath.

SIZE.--Head and body, 2-3/4 inches; tail, 2-3/4 inches.

NO. 359. MUS BACTRIANUS.

HABITAT.--Punjab, Kashmir, Candahar, Baluchistan, and Southern
Persia.

DESCRIPTION.--Upper parts brown above, with a sandy tinge, more on
the head; the longer hairs with a dusky tip; the basal two-thirds
deep ash; under-parts and feet white; tail clad thinly with fine
whitish hair; the fur in general long, dense, and silky.

SIZE.--Head and body, from 2-1/4 to 3-1/4 inches; tail, about the
same.

This is the mouse, I think, that I caught in the house at Simla in
1880. Of eight specimens I got--seven in a cupboard in the
dining-room and one in a bath-room--I sent two in spirits to the
Indian Museum and brought down to Calcutta three alive, which I kept
for about seven months, when they died. I have since then seen living
specimens of _M. bactrianus_ from Kohat, with which they appear to
be identical. They also resemble--I speak under correction--_M.
cervicolor_, which is
