General colour of the body pale yellow, washed with ashy grey or brownish on 

 the nape and back, and with a darker tint of the same colour on the shoulders 

 and the outside of the limbs. A strong line of black supraorbital hairs, as in 

 all its Indian allies : no crest. Hands and feet and their under surfaces and the 

 skin of the face and ears black. The tail is concolorous with the back, but paling 

 towards its tip : it is about one-fourth longer than the body. 



This form is most nearly allied to S. schistaceus, but I have observed indivi- 

 duals which in their bright colours approached closely to the allied form occurring 

 in Assam, viz. S. pileatus. A consideration of the types of S. schistaceus, S.pileatus, 

 S. hypoleucus, and S. priamus, in conjunction with a large series of S. entellus, leads 

 me to believe that in the following synopsis of the group we have the species 

 arranged according to their affinities. I have examined the entelloid monkeys which 

 Colonel Sykes obtained in the Deccan, and which I do not consider to differ specifi- 

 cally from this species. Sir Walter Elliot was inclined to regard the entelloid monkey 

 from Southern and Central India as belonging to a distinct form which he named 

 IS. anchises, and an example of which in the shape of a skin was sent to Blyth at 

 Calcutta, who considered it to be S. entellus. Unfortunately this skin no longer 

 exists in the Indian Museum, and there are no materials at present available for 

 the settlement of this point; but having every reliance on Ely th's judgment in such 

 a matter, I accept his views regarding S. anchises. 



The characters of the skull of this species I enumerate under S. schistaceus. 



This species appears to range from the Deccan northwards to the right bank of 

 the Ganges, but what are the limits of its distribution to the west and north-west is 

 not accurately known, but it reaches to the seaboard to the east, and in the Hima- 

 layas is replaced by 8. schistaceus, to the south-east by S. hypoleucus, and to the 

 south-west by S. priamus. In Assam it is represented by S. pileatus. 



The food of the entelloid monkey appears to consist very largely of the leaves 

 of forest trees.
