SEMtfOPITHECUS. 31 



has observed S. schistaceus near Simla, sporting amongst fir trees 

 that were loaded with snow-wreaths. 



According to a MS. note of Hodgson's these monkeys pair in 

 February and have young in April or May, the period of gestation 

 being apparently only two months. Further information is 

 desirable. 



S. schistaceus is distinguished from 8. entellus (1) by being some- 

 what larger, though there is probably no great difference between 

 large individuals of both species ; (2) by the head being much paler 

 in colour than the back, and by the feet being but little, if at all, 

 darker than the limbs ; (3) by the smaller ears, and by their being 

 concealed by the long hair of the cheeks ; (4) by the form of the 

 skull. Dr. Anderson has shown that the skull of 8. schistaceus is 

 longer in proportion to the breadth, and the face is relatively 

 longer than in S. entellus. If a straight edge be applied to the 

 face, it will be found that in S. entellus the nasal bones do not 

 project beyond a line drawn from the middle of the supraorbital 

 ridge to the anterior border of the premaxillaries, whilst in 

 S. schistaceus the nasals do project beyond that line. These cha- 

 racters appear quite constant in adults. Anderson in his last 

 work, the ' Catalogue of Mammalia in the Indian Museum,' classes 

 S. schistaceus as merely a variety of 8. entellus, but I cannot 

 agree.

The radiation of the hairs on the front part of the crown is less 

 conspicuous than in 8. entellus and S. schistaceus ; the hairs on the 

 hinder part of the crown are elongated along the middle line so as 

 to form a distinct longitudinal compressed crest *. Black supra- 

 orbital fringe very long. Ears large, not covered by the hair of the 

 cheeks. Hair of the body long, with scattered longer piles of the 

 same colour. 



* The existence of this crest was mentioned by Blyth, Jerdon, and Kelaart, 

 and figured by Sir Emerson Tennant, but doubted by Anderson. It is, how- 

 ever, distinctly shown in three dried skins from Ceylon in the British Museum, 

 and as these skins have never been mounted the character is clearly natural. I 

 have also seen it in skins from Southern India, and am assured by Mr. W. Davi- 

 son and others that it is constantly present.
