about the locality Borneo. But I can not find in Murie's paper a 

 new argument in favour of this affirmative title. 



After describing M. maurus he says: 



„In outward aspect there is undoubtedly considerable resemblance 

 between the Moor Monkey and the Ashy-black ape (Macacus ocreatus 

 Ogilby). Indeed in their juvenile stage a most practical naturalist araong 

 living animals (Mr. Bartlett) as well as Dr. Sclater himself, havebeen 

 deceived regarding the two. The former gentleman relates to me how 

 that he purchased two young animals which he in every way regar- 

 ded as representatives of the Bornean Ape (MV inornatus? = M. mau- 

 rus). Much was his astonishment , therefore to find one of them to 

 develope into a typical ashy-black Ape (M. ocreatus.) There can be 

 no doubt they are two forms closely allied. But the adult of the lat- 

 ter is distinguished by a deeper sooty tint of the upper parts, and 

 underneath and on the limbs, and very characteristically displays the ashy 

 hue , wherefore its name. Its tail also is a trifle longer and somewhat 

 curled forwards; and the hair of the head has a bushier appearence. 

 Relatively it is a higher-limbed Monkey than is M. maurus". 



Then follows Schlegel '). He unites two Macaques with this common 

 characters: „Face noire. Teinte dominante du pelage d'un brun s'appro- 

 chant, ordinairement, du noir", and distingaishes them as follows. 

 M. maurus: „Le pelage de ce singe est ordinairement teint d'un brun- 

 noir, plus clair et tirant plus ou moins au grisätre sur le dessus et 

 quelquefois encore sur les joues. Nous en possedons cependant un 

 individu passablement jeune dont la teinte dominante se trouve rem- 

 placee par un brun grisätre peu fonce". 



M. ocreatus: „Cette espece rappelle en general le Mac. maurus ; mais 

 eile s'en distingue, au premier coup d'oeil, par ses bras, ses jambes 

 et la face posterieure de ses cuisses teintes, dans les uns, de jaune 

 brunätre ou roussätre, dans les autres de grisätre. Elle a aussi le 

 museau plus alonge et pourvu, ä l'äge adulte, de deux cötes saillantes". 



From five specimens of Macacus ocreatus investigated by Schlegel 

 only one was „adult", from four specimens of Macacus maurus not one. 

 Therefore the distinction about the longer muzzle seems to be of no 

 value. I brought home alive from Celebes a male and a female. One, 

 the male , was generally brownish black coloured like a Macacus mau-
