468 Notices of various Mammalia. [No. 150. 



just been presented to the Society by the Rev. J. Barbe, R. C. Mis- 

 sionary, which was shot by him during his recent visit to the wild 

 Kookie tribes of the Chittagong hills ; and the same gentleman had 

 previously favoured us with a more than half-grown male killed in 

 Tipperah. These two differ considerably in shade of colour from the 

 young female formerly described, having the whiskers, throat, chest, 

 and front of the shoulder, very deeply tinged with ferruginous, — the 

 rest of the under-parts, the legs all round (from the knee), and much 

 of the humerus, less so, — and the head and back of a more dingy ash- 

 grey, being sullied with the prevalent rust-colour : the half-grown 

 female before described has merely a faint tinge of ferruginous on its 

 whitish under-parts, and the back and limbs are very delicate pure 

 grey.* In the old male, the tail is of the colour of the back at base, 

 becoming gradually black, which last occupies the terminal third or 

 more : the fingers and toes are 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 be- 

 tween and above them, immediately over the glabella or inter-orbital 

 space, the hairs of the forehead are conspicuously tinged with ferrugi- 

 nous : those on the crown are not elongated as in the preceding species, 

 nor is there any trace of vertical crest ; but they are a little lengthened 

 beyond those of the occiput, sinciput, and temples, which they ac- 

 cordingly impend, and thus is presented somewhat the appearance 

 of a small flat cap laid on top of the head, whence the specific name. 

 The length of fore-arm and hand (of the adult male), to tip of 

 longest finger, is above a foot ; knee to heel nine inches ; foot about 

 seven inches : and length of skull about five inches. 



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

 brought together the S. cephalopterus, (Zimmerman,) from Ceylon, 

 with which Mr. Martin identifies the Lion-tailed Monkey Q, and the 

 Purple-faced Monkey, of Pennant, the Guenon a face pourpre of 

 Buffon, Simia dentata, Shaw, Cercopithecus latibarbatus of Geoffroy, 

 Kuhl, and Desmarest, C. leucoprymnus, Otto, Simia fulvo-grisea, 

 Desmarest, Simia leucoprymna et S. cephaloptera, Fischer, S. nestor, 

 Bennett, and S. leucoprymnus et S. nestor, Lesson, — and the S. 



* A half grown male just received from Mr. Skipwith is intermediate in its 

 colouring.
