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 among 
living animals (Mr. Bartlett) as well as Dr. Sclater himself, have been 
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 (M. 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 distinguishes 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 grisâtre sur le dessus et 
quelquefois encore sur les joues. Nous en possédons cependant un 
individu passablement jeune dont la teinte dominante se trouve rem- 
placée par un brun grisâtre peu foncé". 
M. ocreatus: „ Cette espèce rappelle en général le Mac. maurus ; mais 
elle s'en distingue, au premier coup d'oeil, par ses bras, ses jambes 
et la face postérieure de ses cuisses teintes, dans les uns, de jaune 
brunâtre ou roussâtre, dans les autres de grisâtre. Ehe a aussi le 
museau plus alongé et pourvu , à l'âge adulte , de deux côtes 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-
