concave. "Riese differences in the details of the con figuration 

 must confer on 5. priamus a very different visage from that 

 of S. entellm. There is not much difference in the teeth of 

 the two forms, but in S. priamus they are relatively larger 

 than in S. entellus, except the canines, which are smaller.

Via. A staffed adult male and skull, No. 29A of Blyt^s 

 Catalogue. Head, except the eyebrows and skin of face, yellow ; 

 throat, under parts, inside of brachium and thighs yeUow, 

 especially brig^ht on the chest and belly. Brown from the 

 shoulders to the root of the tail, darkest on the middle of the 

 back, paler on the sides and the posterior half, and the outside 

 of the thighs. Antibrachium, front of thighs, and lower half 

 of legs black, light brownish on the front of the tibia. 

 Hands and feet black, concolorous with the limbs. Tail black, 

 brownish towards its tip. Hair of head semi-erect and back- 

 wardly directed; a few black hairs before the ears : nails black. 

 The skull of this species has the general features of the skull 

 of S. priamus, but it is smaller and characterised by much 

 less prominent supraorbital ridges and by considerably less 

 interorbital breadth, with narrow rather compressed nasals, in 

 this respect conforming to the female of S. priamus. The 

 skull is entire, with the exception of the occipital and basi- 

 occipital portion, and its length from the premaxillaries to the 

 lambdoidal ridge is 4'-26, the palate measuring \"T6. The 

 fronto- malar and greatest zygomatic breadth are respectively 

 2"'55 and S^'SO. These measurements show that this species 

 is the smallest of the Indian SemnopHkeci. Travancore.
