black line with numerous long black hairs; whiskers and sides of head 

 white; top of head, upper part of body to rump, shoulders and flanks, 

 ochraceous on some examples, yellowish green in others, the hairs 

 being dark brown at base and ringed with ochraceous and black, or 

 yellow and black ; rump and limbs dark gray tipped with black ; entire 

 under parts, and inner side of limbs white ; hands brownish black, feet 

 reddish ; tail iron gray, ochraceous rufous on sides at root, apical

The specimen figured by F. Cuvier is now in the Paris Museum 

 and has lost a portion of the blackish end of the tail. It is yellowish 

 green in color on the upper parts of the body and in this respect differs 

 from a more recent specimen in the Museum brought from the French 

 Congo in 1902. The difference of tint shown by these examples is 

 probably only an individual variation of hue, for Cuvier's specimen 

 does not seem to be faded to any perceptible degree on the upper 

 parts. The gray portions on the body of the Congo specimen as well 

 as the tail are much darker than on the other. The form described 

 under the name of L. lalandi Geoff., is all dark gray above with a 

 slight wash of olive. The type is not in the Paris Museum, nor any 

 specimen even marked "un des types," and it cannot be determined 

 whether the examples in the collection are those which Geoffroy had in 

 his possession or not, but it is presumable that they are. Grant states 

 that this species is "common in the Dukudukuthorn forest, eight miles 

 south of the station, Hlatwa District, Zululand. 



"Generally seen in parties from six to twelve. In the early morn- 

 ing they sit on the tops of the trees and ant-heaps enjoying the sun. 

 The natives living in the bush eat the 'Nkau,' while those of the open 

 country will not touch it." In Knysna, Cape Colony, the same collector 

 says this monkey is "common, frequents the forest country, and visits 

 the land and gardens near houses doing considerable damage. Gener- 

 ally in parties of six or more, although occasionally I have observed a 

 pair with their young only." 



There is considerable variation in the shades of color from light 

 to dark among individuals, and this is well exemplified in the series in 

 the British Museum procured by Mr. C. H. B. Grant, from various 

 localities. As these differences in intensity of color occur among 

 examples from the same place, it can only be regarded as individual 

 variation, and one of no importance in a scientific sense, and it is 

 observable in quite young specimens as well as in those fully adult. 

 As will be noticed from the localities given above, the species has
