This, which Blyth considered a good species, is, I am informed,
referable with _M. Taraiyensis_ and _M. Morungensis_ to Gray's
_Nesokia Bengalensis_. The type and drawing of it are in the British
Museum.

of Hodgson, described in Horsfield's Catalogue as pure dark brown
above, with a very slight cast of rufescent in a certain aspect;
underneath from the chin to the vent, with interior of thighs,
yellowish-white; ears nearly an inch long; head proportionately long
('Ann. and Mag. Nat. Hist.' new series, iii. p. 203). This, with
Blyth's _M. nemoralis_, seems identical with _M. brunneus_.

_Mus arboreus_ of Horsfield's Catalogue is _Mus rufescens_. It
remains to be seen whether there is sufficient difference between
_M. rufescens_ and _M. niveiventer_ to warrant the separation of the
latter as a distinct species.

The following species lead on to the mice--beginning with the
long-tailed arboreal species, _Vandeleuria_ of Gray, which connect
the arboreal rats with the house mice.

The characteristics of _Vandeleuria_ are: upper incisors triangular,
grooved in front; ears hairy; fur soft, with long bristles
interspersed; long tail, sparsely haired; hind feet very long,
slender; soles bald beneath; toes .45 long, slender, compressed, the
pads much more strongly developed than in ground mice; the inner and
outer toes with a small flattened nail.

NO. 350. MUS OLERACEUS.
_The Long-tailed Tree Mouse_ (_Jerdon's No. 184_).

NATIVE NAMES.--_Marad-ilei_, Canarese; _Meina-yelka_, Telegu of the
Yanadees (_Jerdon_).

HABITAT.--Throughout India from north to south, but has not been
reported from Ceylon. In Burmah Dr. Anderson found it in the valley
of the Nampoung, a frontier stream dividing Burmah from China.

DESCRIPTION.--Upper surface rich rufous or chestnut red, paling to
brown on the ears and muzzle before the eyes; under-parts white, with
a yellowish tinge; feet pale brown, shading off into white on the
toes; under surface of feet yellowish; tail brownish or dusky with
grey hairs; it tapers to a point, finely ringed; sparsely haired
between the rings, the hairs more numerous and longer towards the
tips. The length of the head, according to Dr. Anderson, whose
description ('Anat. and Zool. Res.' p. 313) is more complete than
Jerdon's, is about one-third the length of the body; the muzzle is
moderately long and slightly contracted behind
