having retained the color of pelage of the young, which, although a rare 
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. Geoffroy’s type is a female, its locality un- 
known. This Javan species has usually been known as Simia 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 S. maura. It is difficult to explain why Schreber connected
