LIST OF THE NEW SPECIES OF MAMMALS DISCOVERED BY THE LATE M. MOUHOT IN CAMBODIA AND SIAM.
_Male._--BLACK: back of the head, back of the body, and front hind legs greyish; forehead and circumference of the black spot on the crown paler grey: hands and tuft of long hair round the organ of generation white.
The three specimens in this state are all nearly of the same size, and appear to be adult. They only vary slightly in the size of the coronal spot, and in the extent of the white colour on the hands.
_Female._--White: back brownish white, slightly waved; a large ovate spot on the crown, and a very large ovate blotch on the chest, black.
These specimens are all of one size, and appear to be adult; three have the teats well developed. They vary in the size of the black chest-spot, and in the colour of the whiskers, thus:--
a, b. White: spot on the chest moderate, reaching only half-way down the abdomen: whiskers on side of face white.
c. Brownish: spot on chest larger, reaching further down the abdomen: sides of the face black: a few black hairs on the throat.
d. Brownish: side of the face, under the chin, and the whole of the throat, chest, and belly black: teats well developed.
_Young._--Uniform dirty white, without any black spot on chest or head.
All those varieties were found by M. Mouhot on a small island near Cambodia. (Described by Dr. J. E. Gray, Proc. Zool. Soc., 1861, p. 135.)
Grizzled chestnut-brown, variegated with black and white rings on the hairs: the head and limbs darker chestnut, with scarcely any hair, and very narrow white rings: lips and throat, and under part of the body, uniform duller brown; the nape with longer hairs, forming a broad short crest.
Cambodia. (Gray, Proc. Zool. Soc., 1861, p. 136.)
Grizzled grey brown, with pale rings: lips, chin, throat, and under side of body and inside of limbs white: the upper part of the sides with a longitudinal black streak, edged above and below with a narrow white line: tail blackish, whitish washed, hairs elongate, brown, with two broad black rings and a white tip: ears simple, rounded.
The species differs from most of the squirrels of the size, in the three streaks being on the upper part of the back, and in the dark colour between the two colours of the upper and under surface.
