is quite irregular. Posterior fringe to hind limbs like back, 
or rather tending towards an orange tone. Upper surface of 
hands and feet uniform black; under surface of heel and 
fringe of hind feet brownish black. Tail long, thickly 
clothed, indistinctly distichous ; its proximal hairs yellowish 
or whitish, broadly tipped with brown, its terminal ones 
wholly dark brown. 
Skull decidedly larger than that of S. alboniger, but very 
similar in its proportions, in the relative length of the muzzle, 
and in the size and direction of the postorbital processes. 
Interparietal unusually produced antero-posteriorly, its length 
nearly equalling its breadth. Mastoid portion of bulla 
swollen posteriorly above and behind the meatus. Teeth 
large and heavy, their crests well developed and the valleys 
‘between them deep; 2:4 elongate, its longitudinal diameter 
slightly exceeding that of ™1; surface of teeth with minute 
crenulations ; “= with a minute extra ridge running longi- 
tudinally across the inner end of the main transverse ridge, 
Dimensions of the type (an adult female in skin) :— 
Head and body (c.) 330 millim.; tail 250; hind foot 
(damped) 50; ear from notch (dried and shrunk) 26. 
Skull *: upper length (c.) 51:5; zygomatic breadth 32-5 ; 
nasals, length 15°1, greatest breadth 8°6 ; interorbital breadth 
(ignoring supraorbital notches) 12°3, intertemporal breadth 
12:2; palate, length 28; diastema 10°6; length of upper 
cheek-teeth, from front of ®4 to back of ™3, 11:4; length of 
P-3 alone 3°0.

Besides the type (B.M. 79. 5. 3. 2) there are two other 
skins and a skeleton of this species in the Museum collection ; 
all were obtained by Mr. Everett between Nov. 1877 and 
Jan. 1878. One of the other skins is mottled all over with 
white and is evidently a partial albino. 
The only species with which S. nigripes could be con- 
founded is S. alboniger, Hodgs., a native of Nepal, Sikim, 
N. Burma, &c., and from this it 1s readily distinguished by its 
decidedly greater size, its black lips, black hands and feet 
(in S. alboniger the hands are grey and the feet brown), its 
paler and less thickly haired parachute, and its larger and 
heavier teeth. 
* The following additional measurements are taken on the more 
perfect skull belonging to the skeleton :—Basal length 45°8 ; tip to tip of 
postorbital processes 23:5; horizontal antero-posterior diameter of 
bulla 10:4.
