Mr. E. Blyth's Nutices of varioia Mammuliu. 157 



Bengal Hoomiman because of the diversity of climate which they 

 inhabit, is in ])art nulliHcd by tlie fact that the Macacus Rhestis 

 inhabits alike the liinialaya and the Bengal Soonderbuns; and 

 it also remains to ascertain how high the S. Eatellus may extend 

 uj)on the northern mountains of Assam : moreover it is by no 

 means clear, from the above description, that Capt. Ilutton's 

 jMussoorie Lunyuor is identical with J\lr. Hodgson's Nepalese 

 species. 



Keturning now to the determination of the Simiadre found 

 eastward of the Bay of Bengal, Dr. llelfer mentions two species of 

 Macacus, stating that " the Cercopithecus crjnosiirus\cynomolgus ?] 

 inhabits chi(>tiy the banks of rivers and the mangrove forests, 

 being chietiy fond of shell-tish;" and that "another species of 

 Cercopithecus belongs to the rarest of this genus, and is found 

 chiefly in the northern parts upon isolated limestone rocks." 

 There can be little or no doubt that the two following are the 

 species referred to ; and to Capt. Phayre is due the credit of first 

 secui'ing specimens of these animals for examination, the Society 

 being ah'cady indebted to that gentleman for numerous other 

 specimens of Arracanese mannnalia, several of which are new, and 

 for nearly 200 species of birds, besides sjx'cimens in other classes, 

 to all of which he is continually fast adding. 



Macacus yiemestrinus (?). — A huge specimen of what I conceive 

 to be merely the common piff-iailed monkey of authors, nume- 

 rous in Sumatra, (where three varieties of it are alluded to by 

 Raffles, who terms the species Simla carpolegus,) if not also in 

 other ])arts of the JMalayan archipelago and peninsula, differs 

 from ordiuai-y specimens of its race, such as are commonly seen 

 in capti\ ity, in the development of its coat of hair, especially on 

 the fore-quarters, in having the crown merely infuscated, instead 

 of black (or nearly so), and in the terminal tuft of its tail being 

 bright ferruginous; besides which, there is a strong tinge of 

 golden ferruginous about the shoulders. The coat is fine in tex- 

 ture, and upon the fore-quarters the hairs of it measure from four 

 to fiv(? inches long ; on the loins they scarcely exceed two inches, 

 and on the under-parts are comparatively scanty; the general 

 colour being that prevalent among the Macaci, or grizzled brown, 

 the piles annulated with dusky and fulvous ; crown darker, and 

 the middle of the back posterior to the lengthened hair is also 

 dai'kcr, becoming black along the upper surface of the tail, which 

 has a bright ferruginous tuft as before noticed ; but there is no 

 trace of this upon a veiy young specimen also sent, which has like- 

 \vise little appearance of annulation to its fur, and the colours 

 generally are subdued and much paler. A live example (of un- 

 doubted nemestrinus) which I possess, about a third gi-own, begins 

 to show the grizzling or annulation to the fur of its fore-quarters.
