170 MAGUS

 greatest breadth of Pterion, 55." (Meyer). 



The type of M. inornatus Gray, is an immature animal with a 

 uniform brown color on upper parts and flanks. As it has no par- 

 ticular locality it may possibly be the young of either of the three 

 species of Magus, as these resemble each other so closely when im- 

 mature as to present no indication as to which species they belong. 

 Dr. Sclater once purchased two young, supposedly of M. maurus. 

 One developed into that species, the other into M. ochreatus. 



The Macaciis maurus F. Cuvier, (1. c.) with its entire dark brown 

 pelage and black face would seem to be an individual in immature 

 pelage, for the young of the species of either Magus or Cynopithecus 

 do not resemble the adults, but are generally of a brown color and take 

 on the other hues such as black, gray, etc., as they progress towards 

 maturity. Thus Meyer (1. c.) figures a young female from Bantimu- 

 rung, in south western Celebes, No. 1, an individual, as he states, with 

 "three molars still undeveloped," as altogether in the brown pelage. 

 This example is like the M. inornatus Gray, (1. c.) and both would be 

 the same as M. maurus^ which is supposed to come from that part of 

 Celebes, if M. inornatus really comes from the same part of the island.
