In general appearance this is a silvery gray animal with black 

 showing more or less distinctly on various parts of the body. 



This species has usually gone under the name of pruinosus Des- 

 marest, published in the Supplement to his Mammalogie in 1822. But 

 in his synonymy of P. melalophus (!) he cites the volume of the 

 Transactions of the Linnsean Society in which Raffles had described this 

 species as cristatus, therefore he must have seen Raffles' paper before 

 this Supplement was published, and his name of pruinosus would 

 naturally become a synonym of cristatus. Anderson, (1. c.) describes 

 a female from an unknown locality as Semnopithecus routlcdgi. He 

 gives no information as to the place or Institution in which he 

 deposited his examples, and I was unable to find it in the Calcutta 

 Museum. It is probably the same as P. cristata.
