1893.] MOXKETS OF THE GEITIJS CEKCOPITHECTJS. 255 



The Diana Monkey is by no means scarce in captivity, and 

 during the past thirty years we have had at least 25 specimens of 

 it living in the Society's Monkey-house. 



In Gray's Catalogue of Monkeys (p. 22) a " var. ignita " of this 

 species is constituted, as ha\'ing " the back edge and inner side of 

 the thighs bright red-bay." On May 31st, 1SS9, we received, as a 

 present, from Col. Wethered of Great Mai-Iow, a female Monkey 

 of this form, of which I now exhibit the skin. Besides the 

 difference above referred to, it vviU be observed that the white 

 frontal band is not so well marked in this specimen, and that the 

 black of the chin is carried down over the upper part of the beard, 

 ■which is shorter than in C. diana trjpicus. I propose to designate 

 this subspecies C. diana ignitus. Col. Wethei'ed kindly informs 

 me that the specimen in question was brought from the Congo by 

 Capt. Moore-Harper in 1886, so that C. diana ignitus is probably 

 a southern form of O. d. ty_picus.

exhibition. It is certainly most remarkable for its elevated red 

 frontal band, which is composed of short erect hairs. This is 

 bordered behind by a broad black band, which extends to the ears 

 on both sides, and in front by a narrow black stripe over each eye. 

 The upper portion of the nose is black, the lower portion, together 

 with the cheeks and lips, is covered with short white hairs. The 

 beard on the chin and throat is long and abundant, formed of white 

 hairs. 



This peculiar Monkey was discovered by M. Jacques de Brazza,
