1844.] Notices of various Mammalia. 469 



Johnii, Fischer, from the Neilgherries, to which Mr. Martin only 

 refers the S. cucullatus, Is. Geoffroy. 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 with the present species, as I have shewn in J. A. S. XII, 

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

 X, 839. The name cephalopterus would have to be retained, and the 

 animal appears subject to considerable variation of shade; a half- 

 grown female before me resembling Mr. Martin's figure referred to S. 

 cephalopterus, except that the croup is pale-grey as stated in the des- 

 cription, the hair there being shorter ; and there is an admixture 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 

 chesnut- brown, and lengthening on the occiput: the tail of this is 

 whiter to the end. An old male, on the contrary, has dark dull 

 chesnut-brown whiskers, concolorous with the hair of the crown, and 

 some blackish hairs growing in front of them ; and his tail is blacker 

 to the end : the hair on the crown is all elongated, but increasing in 

 length to the occiput, where some of the hairs exceed five inches in 

 length, and tend to be albescent, a sort of dingy isabella colour pre- 

 vailing, which is not easy to express in words. On the short hair 

 of the croup, and upon the thighs, the same grey colour appears as in 

 the young female specimen, but is mingled with black, and consider- 

 ably less albescent. The bodies and rest of the limbs of both are deep 

 black, but picked out a little with greyish in the young female. I 

 consider these two specimens to respectively represent the S. cephalop- 

 terus and 5. Johnii of Mr. Martin'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 confounded under S. entellus.
