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. Cambodia. (Named by Dr. J. E. Gray, after M. Mouhot, and described in Proc. Zool. Soc., 1861, p. 137.) 4. _Sciurus splendens._ All the specimens are bright red bay. _Var._ 1.--All over dark, and very intense red bay, with a white spot on each side of the base of the tail. _Var._ 2.--Top of the head and tail, like var. 1, dark and very intense red bay: side of the back, under sides of the body, and tip of the tail paler red bay, without any white spot at the base of the tail. _Var._ 3.--Uniform pale bay, like the side of var. 2: tail and middle of the back rather darker and brighter: tail without pale tip or white basal spot. _Var._ 4.--Crown, middle of the back, and tail dark intense red bay: throat, chest, and under side paler red bay, like var. 2, 3: cheeks, shoulders, and thighs, and outsides of the fore and hind legs brown, grizzled, with yellow rings on the hairs: side of the body rather greyish red. Cambodia. (Gray, Proc. Zool. Soc., 1861, p. 137.) 5. _Sciurus siamensis._ Bright red-brown, grizzled, with elongate black tips to the longer hairs, each of which is marked with a broad subterminal yellow band. These black hairs are more abundant and have broad pale rings on the rump, outside of the thighs, and especially on the lower part of the tail, where they nearly hide the general red colour. The terminal half of the tail bright chestnut-brown, without any black hairs or pale rings. The throat, breast, belly, lower part of sides, inner side and edge of the legs, uniform bright red-brown: ears rounded: whiskers black: feet covered with short close-pressed hairs. (Gray, Proc. Zool. Soc., 1859, p. 478.) _d._ RUMINANTS. 6. _Tragulus affinis._ Similar to T. javanicus in colour, but rather smaller and much paler, and the side of the neck similar in colour to the side of the body: the belly is white, with a brown streak on each side of the central line: the head is smaller. It is larger than _T. kanchil_; very much paler; and the neck is not blacker and grizzled. A specimen of the species has been in the British Museum, as above named, for many years: it is said to have come from Singapore; but that probably was only the port of transit. It may be only a small pale local variety of _T. kanchil_. Six specimens, adult, all exactly similar, and one young, have been collected by M. Mouhot. (Gray, Proc. Zool. Soc., 1861, p. 138.) 7. _Cervulus cambojensis._
