CYNOPITHECUS 161 



Cynopithecus, to follow him in this part of his paper would 

 take us too far afield, and we will consider his review only as it 

 relates to the black monkeys of Celebes. He recognizes the 

 following species : C. nicer Desm., C. nigrescens Temm. — C. 

 NIGER, with a comparison of their skulls ; C. tonkeanus Meyer ; 

 P. inornatus Gray, = C. maurus (F. Cuv.), juv. ; C. ochreatus 

 Ogilby, and C. maurus (F. Cuv.). He describes as distinct 

 from these P. hecki, probably from Buol, in the northwestern 

 peninsula, the locality from which P. nigrescens Temm., was 

 described, and hecki is the same as that form ; P. tonstis from 

 an immature animal and no locality, which = C. tonkeanus 

 from the eastern or middle peninsula ; P. hypomelas no locality 

 given, but which he says is not quite adult and stands between 

 his tonsus and inornatus, and its skull is similar to that of the 

 last named, inornatus, and with that form also, both = C. 

 MAURUS (F. Cuv.) ; and lastly, P. brunescens from the south 

 easterly peninsula, and Island of Buton. The type of this 

 last named is a very young animal, too young to exhibit any 

 distinctive characters, and probably is the same as C. 

 OCHREATUS which inhabits the same peninsula. In order to 

 localize the species described, the various peninsulas have been 

 divided into northern, southern, eastern and western portions, 

 without any definite information that the forms indicated are 

 thus restricted. 



GEOGRAPHICAL DISTRIBUTION OF THE SPECIES. 



It must be confessed that with only our present inadequate 

 knowledge of the species of the genera Cynopithecus and Magus, 

 t?xeir distribution in the Island of Celebes is mostly guesswork. 

 Matschie's dispersal of the species he recognizes is, at least in part, 

 purely imaginary, and he has no positive information that any of the 

 species were restricted within the boundaries he gave them. We think 

 we know that certain species come from certain parts of the island, but 

 what may be their boundaries, or whether they have any at all, we have 

 no certain knowledge. The following is supposed to be the dispersion 

 of the species recognized in this work : In the northern peninsula from 

 Minahassa on the east to Tomini on the west, and down the west coast 

 to Balanipa, and also on the small mountainous Island of Menado-toua 

 oflf the northeastern extremity of Celebes, and the Island of Batchian, 

 C. NIGER is found.
