48 Mr. 0. Thomas on a new Ceplialolophus. 



IX. — On a neio Ceplialolophus /ro??i Mount Kilima-njaro. 

 By Oldfield Thomas. 



Mr. F. J. Jackson has presented to the British Museum the 

 head of a Cephaloloj)hus obtained by him some years ago on 

 or near Mount Kilima-njaro. This head is clearly that of 

 the animal doubtfully determined as C. nigrifrons* in 

 Mr. F. W. True's excellent account of Dr. Abbott's Kilima- 

 njaro collection, and is also, I believe, specifically identical 

 with a skin obtained many years ago by Sir John Kirk at 

 Malindi, and, owing to its having lost the fur of its face, 

 erroneously referred by me to G. natalensis^ Sm., in my recent 

 monograph of the genus !• 



At Mr. Jackson's suggestion I propose to name the species 

 in honour of Sir Robert Harvey, who was the first of their 

 party to shoot a specimen of this interesting species ; and 

 taking first as my type the Kilima-njaro head only, it may be 

 briefly diagnosed as follows : — 



Cephalohphus Harveyi, sp. n. 



Colour of face and nape as in C. nigrifrons^ i. e. ground- 

 colour chestnut, with a black blaze extending from the nasals 

 to the occiput, expanding on the forehead ; of cheeks, sides of 

 neck, and throat pale bay, and of chin white, as in 0. naia- 

 lensf's. Horns of male conical, very thick at the base, their 

 greatest basal diameter going barely two and a half times in 

 their length. 



Dimensions of head : — Muzzle to eye 95 millim. ; to occiput 

 188 ; ear above crown 70 ; horns, length 79, greatest basal 

 circumference 77. The dimensions given by Mr. True may 

 also be referred to. 



Hab. Mount Kilima-njaro. 



But if, as I see no reason to doubt, the Malindi skin and 

 skull are also referable to this species, the following points of 

 difference from C. nigrifrons may also be noted : — 



General colour much paler, almost exactly as in C. nata- 

 lensis ; under surface decidedly paler than upper j feet slen- 

 derer and more delicate throughout ; hoofs not elongated \ 



* Proc. U. S. Nat. Mus. xv. p. 476 (1892). 



t P. Z. S. 1892, p. 419. Owing- to tins specimen proving not to be 

 C. natalensis, it will be necessary in the account {I. c.) of that species to 

 delete all references to the male, including description of male bonis and 

 measurements of skull, tbese being all based on this Malindi specimen. 



X It is probable that the true C. nigrifrons is an inhabitant of swamps 

 and marshes, as its hoofs are so very markedly elongated as compared to 

 those of its congeners. The measurement above given is between 30 and 

 35 millim. in the type specimen.
