SIMIAD.E. 469 



hairs traverses the forehead ; the hands and feet are blackish ; the tail is 

 brown ; size, that of the Diana Monkey. 



" Description. The face is but little elongated, blackish and naked ; 

 a row of stiff, black, and very long bristles is observable on the super- 

 ciliary ridge ; these are erected upward and forward, and some are placed 

 on the margin of the cheeks, rigid in texture, and directed laterally ; 

 the cheeks, the top of the head, the back of the ears, and the chin are 

 thinly covered with whitish hairs ; the ears are large, naked, angular, and 

 black ; the shoulders, flanks, and outer surface of the humerus and 

 of the thighs, are of a light grey ; the middle of the back is of a 

 deeper grey, expanding and becoming more dusky towards the lumbar 

 region ; the abdomen is white, and but thinly covered with hairs ; the 

 limbs, externally, are of a deepish grey ; the top of the hands and feet 

 blackish ; the tail is longer than the body, slender, and of a greyish brown. 



" Country. The island of Sumatra." 



Respecting the C. albo-cinereus, M. Isidore says that no such animal 

 was ever brought from India by MM. Diard and Duvaucel, answering 

 to Desmarest's description, nor does any Guenon, agreeing with it, exist 

 in the Museum of Paris. During the Author's recent visit to Paris, he 

 examined, separately, every Monkey in the Museum, and, certainly, 

 could discover no species to which the description can be said to be 

 fairly applicable. Moreover, every specimen brought over from Java 

 or Sumatra, and obtained there by MM. Diard and Duvaucel, is well 

 known, and the species are not to be mistaken. 



In the Catalogue of Zoological Specimens, appended to the Life of 

 the late Sir T. Stamford Raffles, is introduced the Semnopithecus (?) 

 fascicularis (Simia fascicularis, Raffl. Linn. Trans, vol. xiii. p. 246), with 

 this observation : " No specimen of this species, although it appears to be 

 frequent in the forests of Sumatra and the Malay Islands, was found in 

 Sir Stamford's collection. It is, of course, doubtful whether it is a true 

 Semnopithecus." By way of comment upon this passage, it may be 

 stated, that the Simia fascicularis of Raffles, of which two specimens exist 

 in the museum of the Hon. East India Company, and were thus entitled 

 under the surveillance of Sir Stamford, is, certainly, the Macacus car- 

 bonarius ; and it is impossible to imagine on what grounds, with Sir 

 Stamford's description before him, Fischer could have given the S. fas- 

 cicularis as a synonym of S. comatus, an error which has led to no 

 little confusion. There will be occasion to refer to this subject in the 

 description of the Macaque alluded to. 



GENERAL HISTORY. Of the habits of the Semnopithecus comatus, 

 or Croo, we have no definite accounts. So closely, however, do the 

 Semnopitheci resemble each other in manners and general economy, 

 that the details respecting one species are, to a great extent at least, 

 applicable to all.
