three-quarters in total length, inclusive of the protruding incisor 

 teeth ; greatest breadth (of zygomata) three inches ; vertical height 

 (including lower jaw) three inches and one-eighth; length of bony- 

 palate an inch and seven-eighths ; breadth of ditto three-quarters 

 of an inch. The corresponding measurements of a female skull 

 are — four inches and three-quarters, two and seven-eighths, three 

 inches, one and five-eighths, andnearly three-quarters of an inch. 

 The upper canines of the male project nearly five-eighths of an 

 inch from the bony socket. Capt. Phayre sent the following 

 note respecting the habits of this animal: — "These monkeys 

 frequent the banks of salt-water creeks, and devour shell-fish. 

 In the cheek-pouch of the female were found the claws and body 

 of a crab :^^ accordingly, there can be little hesitation in identi- 

 fying it with the other species of Dr. Heifer, to which the same 

 habits were assigned. 



Of the species of this genus, one only appears to inhabit Ben- 

 gal, the M. Rhesus, which is numerous in the Soonderbuns, where 

 its habits, I suspect, pretty much resemble those of M. cynomoU 

 gus : it frequents thick jungly situations, particularly about the 

 borders of narrow gullies, and to escape pursuit will sometimes 

 plunge into the water from an overhanging tree, swim to some 

 distance beneath the surface, and then land and make off on the 

 opposite bank. The Hoonuman, on the contrary, would appear 

 never to enter the water. The M. Rhesus also occurs, as we have 

 seen, even on the Himalaya so far westward as Simla, and Mr. 

 Hodgson has sent it from Nepal, where I cannot help suspecting 

 that (in different phases) it constitutes both his M. oinops and M. 

 pelops (Journ. As. Soc.ix. 1213); and it is included in Dr. Walker's 

 list of the mammalia of Assam (Calc. Journ. Nat. Hist. ii. 265), 

 together with another species discovered in that part by Dr. Mc 

 Clelland, and desci'ibed as M. assamensis in Proc. Zool. Soc. 1839, 

 p. 148. Still further to the north-west, " monkeys '^ are stated by 

 Elphinstone to be found only in the north-eastern part of Affghan- 

 istan : but no Simiadce are included in an elaborate paper on the 

 mammalia of that country, prepared for publication by Capt. 

 Thos Hutton, nor have I seen any subsequent notice of their 

 occurrence in that vicinity. In the Indian peninsula generally, 

 the common species of Macacus is the M, radiatus, being the 

 only one included in the catalogues of Messrs. Sykes and Elliot ; 

 but M. sinicus is likewise found in the southernmost part and in 

 Ceylon, as is also the M. Silenus. 



The following is a brief synopsis of the Indian species of >8^j- 

 miadoi, with those of Assam^ Arracan, and the Tenasserim pro- 

 vinces, as far as they are at present ascertained : — 



1. Hylobates sijndactylus ; Simia syndactyhj Raffles. Stated 

 by Heifer to extend as high as 15° N. lat.
