168 MAGUS / 



top of head gray, streaked with black; upper parts, shoulders, sides 

 of body and outer side of thighs black ; whiskers white ; arms and legs 

 white streaked with black ; hands and feet black ; under parts blackish ; 

 chest grayish white ; ears black ; buttocks hairy ; callosities small, red. 



This was a large animal for the species of this genus, powerfully 

 and compactly built, and in appearance was a grayish white monkey 

 with a black back. The head was round in shape, the muzzle rather 

 short, and the hair on the crown was thick, and short without any indi- 

 cation of the crest. It was said to have come from Celebes, but no 

 particular locality on the island was given. It was evidently one of 

 the finest species of Magus. 



One of the characters that seems to separate maurus F. Cuv., 

 from OCHREATUS Ogilby, is the color of the hands and feet, these 

 being grayish in maurus and black in ochreatus, the young of both 

 being more or less brown according to age. The material for the 

 study of the development of these animals is insufficient in all Mu- 

 seums, and if all that are contained in collections were brought together, 

 it would not be enough to determine how many species there really are. 

 The specimens that have been named and described have, in the great 

 majority of cases, been young animals, some even without localities, 

 and in such cases it is impossible to say, with any degree of certainty, 

 to what species they belong. Dr. Meyer did not appear to know M. 

 OCHREATUS, and the determination of his specimens seemed to depend 

 on whether or not they were M. maurus. Cuvier's type is not a 

 fully adult animal, but the color of its hands and feet would seem to 

 prove it was not M. maurus, but more probably the animal was in a 

 state of pelage characteristic of M. ochreatus. 



Meyer, (1. c.) in his plate of M. maurus F. Cuv., figures two indi- 

 viduals which I consider are (C) ochreatus Ogilby, and numbered 



2 and 3. No. 2 is a young male from the island called Buton at 

 the extremity of the southeastern peninsula of Celebes, the locality 

 which Matschie (1. c.) apportions to his C. brunescens. This No. 2 

 is brown with forearms and thighs gray, but no jet black yet appear- 

 ing on the pelage anywhere, saving outside of the rostrum. No. 



3 is a young female from Kandari, on the eastern part of the south- 

 eastern peninsula of Celebes in the range Matschie gives to M. ochrea- 

 tus. This individual has the three molars still undeveloped, as in 

 No. 2, but it is nearly all black with the gray arms, legs and throat 

 of the adult M. ochreatus. Matschie's brunescens, the type, is a 

 very young animal, too young to have any reliable specific characters 

 established by it, but as we know that the young of M. ochreatus are
