1907.] MAMMALS FROM ANNAM. 9 



present seiies, howevei-, shows tliat they are really quite good and 

 distinct species. The most obvious difference is in the colour of 

 the under parts. In *S'. griseimanus they ai'e deep chestnut and the 

 line of demarcation between the upper and under parts is sharply 

 divided. In «S'. leucopus, on the other hand, the colour of the 

 under parts is of a pale rufous buff, which shades gradually into 

 the grizzled grey of the back. M. Milne-Edwards in his original 

 description of S. griseimanus distinctly states that the colour 

 of the under parts is deep chestnut, though females and j^oung 

 males are sometimes considerably lightei-. This enables us to 

 fix M. Milne-Edwards's name on the chestnut-bellied form with- 

 out hesitation. In the present series the colour of the under 

 parts is very deep chestnut and shows but little variation ; the 

 two examples from Bali, at an altitude of 250 metres, are, how- 

 ever, much lighter below, and it may be that these lighter 

 individuals represent a mountain lace of >S'. griseimanus, but our 

 material is at present too scanty to settle that question. 



S. leucopus differs still fvirther from S. grisei'manus in the 

 annulations on the hairs of the back being yellower and not of 

 such a clear grey, thus giving the animal a darker appearance. 

 The colour of the under pai-ts also extends over the outer sides of 

 the limbs and is especially noticeable on the thighs.

Abstr. P.Z.S. 1907, p. 2 (Jan. 22, 1907). 



General coloiTr above similar to that of S. leucopus, but darker 

 (see pi'eceding species). Each hair is very dark, with three or four 

 yellowish annulations. The tail, which is indistinctly barred, is 

 similar in colour to the body, but the annulations are of a slightly 

 deeper tint. Hands and feet dirty yellowish white grizzled with 

 darker. Under parts and inner sides of the limbs pale reddish 

 bufi", with the exception of the chin and throat which are grizzled 

 like the back. 



The skulls available are so imperfect that a description is not 

 possible. 



Dimensions of type (from skin). Head and body 190 mm.; 

 tail 175 ; ear 17 ; hind foot 52.

Type. B.M. 6.11.6.25. Collected on the 10th Nov., 1905, by 

 Dr. Vassal. 



This species is easily distinguished fi'om >S'. leucopus typicus by 

 its darker colour above, grizzled hands and feet, and by the outer 

 sides of the limbs being similar in colour to the rest of the upper 

 parts. Whereas the typical H. leucopms is gi'eyer, the outer sides 

 of the limbs are buff, and the hands and feet pure yellowish white.

* Since the reading of this paper it has been pointed out to me that the name 

 "fumifjatus " is preoccupied, haying been used by Gray in 1867. I therefore propose 

 to rename this squirrel Scmrws vassali.
