s_,[27] but the rodential tusks are broader and flatter to the
front. Molars as in the _Muridae_ generally, but much worn in the
specimen under examination; they are considerably less directed
outward than usual, and the bony palate has therefore the appearance
of being narrow; the superorbital ridges project much outward in form
of a thin bony plate, and there is a considerable process at the base
of the zygoma anteriorly and posteriorly to the anti-orbital
foramen; zygomata broad, and compressed about the middle."

We have now come to the end of the purely murine group as far as they
exist within the limits assigned to these investigations. I ought
perhaps to give some short notices of the following specimens
discovered in Thibet by the Abbe David, and described by Professor
Milne-Edwards in his 'Recherches sur les Mammiferes.'

NO. 381. MUS OUANG-THOMAE.
_The Kiangsi Rat_.

HABITAT.--Kiangsi in Thibet.

DESCRIPTION.--A tawny grey above, mixed with long hairs, tipped with
brown, greyish below; between the fore-paws a crescent of pure white,
which is a distinguishing mark of the species.

SIZE.--A little less than _Mus rattus_, which is about seven inches
long; tail an inch longer.

This rat Professor Milne-Edwards describes from a single specimen;
it is apparently rare, and was named after the Abbe David's Chinese
servant--'Recherches sur les Mammiferes,' p. 290.

NO. 382. MUS FLAVIPECTUS.
_The Yellow-breasted Rat_.

HABITAT.--Moupin; Thibet.
