rains (as I am infoiincd by F. Skipwitli, Esq., judge and magis- 

 trate of Tii)pcrali), and it Avould api)cnr also to extend sparingly 

 upon the Naga range eastward of Upper Assam. A tine speei- 

 men of an old male has jnst bi-en presented to the Soeiety by 

 the Rev. J. Barbe, U. C. ^Missionary, whieh was shot by him 

 (luring his recent visit to the wild Kookie tribes of the Ciiittagong 

 hills ; and the same gentleman had prencMisly favoured us with 

 a more than half-grown male killed in Tipperah. These two 

 differ considerably in shade of colour from the young female for- 

 merly described, having the whiskers, throat, chest and front of 

 the shoulder very dee])ly tinged with ferruginous; the rest of 

 the undcr-parts, the legs'all round (from the knee), and nnieh of 

 the humerus, less so ; and the head and back of a more dingy 

 ash-gray, being sullied with the prevalent rust-colour. The half- 

 grown female before described has merely a faint tinge of ferru- 

 ginous on its whitish under-])arts, and the back and limbs are 

 very delicate pure gray*. In the old male, the tail is of the 

 colour of the back at base, becoming gradually Idack, which last 

 occupies the terminal third or more; the lingers and toes arc 

 blackish, with an admixture of this on the back of the hands : 

 the long black superciliary hairs spread into two lateral masses 

 (in all three specimens) and are very copious, and between and 

 above them, immediately over the (jJnbcUa or inter-orbital space, 

 the hairs of the forehead are conspiciiously tinged with ferrugi- 

 nous ; those on the crown arc not elongated as in the })reccding 

 species, nor is there any trace of vertical crest ; but they are a 

 little lengthened beyond those of the occiput, sinciput and tem- 

 ples, which they accordingly impend, and thus is presented some- 

 what the appearance of a small flat cap laid on the top of the head, 

 whence the specilic name. The length of fore-arm and hand (of 

 the adult male) to tip of longest linger is above a foot ; knee to 

 heel nine inches; foot about seven inches; and length of skull 

 about live inches. 



As a third continental species of this subgroup, I suspect must 

 be brought together the *S^. cephaJopterus (Zimmerman), from 

 Ceylon, with which Mr. ]\Iartin identities the lion-tailed mon- 

 key y8, and the purple-faced monkey of Pennant, the Guenon 

 a face pourpre of Buffon, Simia dcntata, Shaw, Cercopithecus lati- 

 barbatus of Geoffroy, Kuhl and Desmarcst, C. feucoprymnus, Otto, 

 Simia fulvo-yrisea, Desmarcst, Simia leucoprymna and S. cepha- 

 loptera, Fischer, *S'. Nestor, Bennett, and S. Icucoprymnus and S. 

 Nestor, Lesson, and the S. Johnii, Fischer, from the Neilghen-ies, 

 to which ]Mr. Martin only refers the S. cucullatus, Is. Geoffroy. 



• A lialf-grown male jijst received from Mr. Skipwith is intermediate in 

 its colouring.
