 occurrence does sometimes happen, as is stated by Mr. Shortridge, the 

 British Museum Collector, who sent several females from Java in the 

 pelage of C. auratus. Geoffrey's type is a female, its locality un- 

 known. This Javan species has usually been known as Simla maura 

 Schreber, and supposed to be founded, as asserted by Messrs. Thomas 

 and Wroughton (1. c.) upon the middle sized Black Monkey of 

 Edwards in his Gleanings of Natural History. It is a fact that 

 Schreber cites Edwards in his synonymy, but the description of his 

 "Morhaffe" has nothing whatever to do with Edwards' Black Monkey, 

 and is not founded upon it. Schreber had a baby yellowish brown 

 monkey, seven inches long, in spirits, as he states, and this was the 

 type of his 5". maura. It is difficult to explain why Schreber connected
