of the animals , independent of sex but perhaps not of age. In all , 

 the face and ears are nude and black , the buttocks surrounding ischia 

 rosy, the tail short, stumpy and curled. In some animals, generally 

 the smaller ones, the general colour is brownish black, in others, 

 generally the older ones, the trank above and below brownish or 

 brownish black or sooty black on the upper parts. The limbs of the 

 same colour, only the bind parts of the thighs ashy, or the whole 

 limbs have this ashy hue or are greyish externally. In one very 

 large specimen (N°. 333) the colour was brownish black with two 

 greyish patches on the gluteal-streak. 



One füll grown female (N°. 315) 43,51 cm. long from vertex to anus , 

 with a brownish coloured young one, had white hairs on the black 

 face, white spots on the black ears, hairs on the vertex and on 

 the parts surrounding the anus white, trank brownish black. Limbs 

 with white patches on the medial parts and nearly without hair, 

 lateral parts black with only slight downy white hairs. In another 

 füll grown female (N°. 334) the limbs are nearly without hair, those 

 on the vertex white, on the trank greyish. The skin of the face, ears 

 and limbs is white with black spots. The palm of the hands and the 

 sole of the feet are nearly white. 



These last two cases belong to a sort of albinisme and are of no 

 special interest for us. Of more importance are the different colours 

 described above that may be observed in different specimens living 

 together. 



They agree in all parts with the descriptions given by various 

 authors of Macacus ocreatus and of Macacus maurus. The last is called 

 without any authenticity the Bornean ape. 



The history of this ape is as follows: F. Cuvier ') gives 1823 a 

 figure ,,que nous devons ä M. A. Duvaucel et qui (le singe) se trouve dans 

 l'Inde". Furtheron he adds that it is „propre au continent de l'Inde" 

 and calls this specimen, that he only knew from the figure of Duvau- 

 cel, Macacus maurus. 



Sclateb 2 ) was then the first that saw a living specimen that „seems to 

 belong to Macacus maurus as figured by Cuvier .... Having the tail 

 reduced to a mere naked tubercle , hardly an inch in length. The hair
