For nearly a hundred and fifty years this animal has been given 

 the wrong name by all writers. Linnaeus first called it Simla sphinx, 

 and then afterwards renamed a young Mandrill Simia maimon. In 

 my paper in the Annals and Magazine of Natural History, (1. c.) the 

 error into which all writers have fallen is corrected, and an explanation 

 given, which is not necessary to repeat here. 



The Mandrill is a thick-set powerful creature, whose face and 

 buttocks are colored to an extravagant degree in blue and red, and 

 when the animal is excited these hues are intensified. The head is very 

 large in proportion to the body, and with the face painted, like that of 

 a circus clown, and the small eyes deep set beneath the overhanging 

 brows, it presents a bizarre and forbidding aspect. It is said to go in 

 companies and the adults are very savage, their great strength and for- 

 midable canines, over an inch and a half long, making them dangerous 

 antagonists, before whom an unarmed person would have a small 

 chance of escaping with his life. They eat almost everything in the 

 shape of food that can be masticated, but insects and fruits are the 

 chief articles of their diet. 



The females and young have the rostral ridges less prominent and 

 differ in hue, and the end of the nose which is scarlet and so con- 

 spicuous in the males, is black.
