This is a gray long-tailed monkey of Burma, Arakan, and Malay 

 Peninsula, always known as M. cynomolgos (nee Linn.), until 1825, 

 when Frederic Cuvier (1. c.) described it and called it Macacus irus. 



The above description represents the typical style of this species, 

 but there are considerable variations among individuals both in the 

 color of the pelage and in that of the face. This black handed 

 and black footed Macaque does not seem to go south or east of the 

 Malay Peninsula, but is supplanted by allied forms with gray hands 

 and feet in Java, Flores, Borneo, etc. 



Top of head and upper parts of body speckled brownish red 

 and yellow, the hairs being gray at base and ringed with yellowish 

 red ; shoulders and thighs gray tinged with yellow ; sides of head, 

 whiskers, under parts, and inner side of limbs sooty gray; forearms 

 gray tinged with brown ; tail very long, blackish brown at base, grading 

 into grayish brown on apical portion. Face flesh color. Locality 

 Bengal a mistake, as no monkey of this character is found there. 



It has been shown by Blanford (1. c.) that Linnaeus' cynomolgos 

 was misapplied by Schreber to Buffon's "Macaque," which is the Crab- 

 eating Monkey of Burma, and for which F. Cuvier (1. c.) instituted 

 the name of irus which is the one it should bear. This species has 

 naturally nothing to do with cynomolgos ( !) Linnaeus, which, as has 

 been shown, was an African Monkey = Simia hamadryas Linn., and 

 all the confusion existing in connection with this name has been 

 caused mainly by Schreber. 



Two rather striking varieties of the Crab-eating Monkey have 

 been accorded different names and separated as distinct. The first 

 with a dark-colored pelage and dusky face was called carbonarius by 

 F. Cuvier, (1. c.) and the second, a golden colored animal with a pale 

 face was designated aureus by I. Geoffroy, (1. c). These two forms, 

 as well as the typical style are found in Burma as stated by Blanford,
