454 Mr. E. Blyth's Notices of various Mammalia. 



From specimens now before me^ I think there can be no doubt 

 of the identity of all of these, and that the species both inhabits 

 the Neilgherries and the mountains of Ceylon ; but Mr. ^Martin 

 erroneously identified one specimen in the Paris museum \Nith 

 the present species, as I have shown in 'Journ. As. Soc' xii. 

 170, the animal in question being evidently my S. hypoleucos 

 (Journ. As. Soc. x. 839). The name cephahpterus would have 

 to be retained and the animal appears subject to considerable 

 variation of shade; a half-grown female before me resembling 

 Mr. Martinis figm-e referred to S. cephahpterus, except that the 

 croup is pale gray as stated in the description, the hair there 

 being shorter ; and there is an admixtm-e of this on the thighs, 

 and slightly up the back ; the whiskers, and hairs on the lips 

 and chin are dull white, and those of the crown dull chestnut- 

 brown, and lengthening on the occiput ; the tail of this is whiter 

 to the end. An old male, on the contraiy, has dark dull chest- 

 nut-brown whiskers, concolorous with the hair of the cro^Mi, and 

 some blackish hairs grovang in front of them, and his tail is 

 blacker to the end ; the hair on the cro\^^l is all elongated, but 

 increasing in length to the occiput, where some of the haii's ex- 

 ceed five inches in length, and tend to be albescent,' — a sort of 

 dingy isabella-colour prevailing, which is not easy to express in 

 words. On the short hair of the croup and upon the thighs the 

 same gray coloiu* appears as in the young female specimen, but 

 is mingled \nth black and considerably less albescent. The 

 bodies and rest of the limbs of both are deep black, but picked 

 out a little with grayish in the young female. I consider these 

 two specimens to represent respectively the /S. cephahpterus and 

 >S. Johnii of ]\Ir. INJartin's work, the latter (or old male) being 

 certainly from the Neilgherries, and the other I purchased alive 

 in Calcutta, and could not learn whence it had been brought ; 

 but I am quite satisfied of the specifical identity of the two, and 

 have seen others variously intermediate. Upon these grounds I 

 venture to bring the two alleged species together. 



The other Indian Semnopitheci form a particular subgroup, 

 well-characterized by their physiognomy ; and all of them have 

 a radiating centre of hair on the forehead, a little behind the 

 superciliary ridge. They have been mostly confoimded under 

 S. Entellus. 



The most different from the rest is S. hypoleucos, nobis 

 (Journ. As. Soc. x. 839 and xii. 170), which is characterized by 

 its comparatively small size, deep colouring, and black fore-arms 

 and hands, feet and tail, the head being of a dirty pale straw- 

 colour. Inhabits the iMalabar range and Travancore. 



Next, S. Entellus (verus), F. Cuv., is the representative of the 

 group in Bengal and Assam, extending (as I have been informed)
