ciniens still remain upon one or two farms in the north 

 of the Cape Colony in Victoria West. 



Cephalophus silvicultor (Afzelius). 



See my paper on this subject in the Notes from the 

 Leyden Museum, Vol. XXII, p.p. 179—187. Perhaps there 

 are two new species allied to silvicultor, viz. Thomasi and 

 Sclaterij cf. p. 187. 



Cephalophus leucochilus, n. sp. 



In February of 1899 died in the Rotterdam Zoological 

 Garden an adult female-Antelope, strongly resembling Gray's 

 Cephalophus breviceps, figured and described in P. Z. S. L. 

 1866, . p. 202, pi. XX. The latter animal was from an 

 unknown locality, Gray wrote » West- Africa?". Our speci- 

 men is from the Loango-coast. 



Dr. Sclater later on (P. Z. S. L. 1869, p. 594) however 

 learned us that Gray's animal was a young individual and 

 that it about a year afterwards became darker colored, 

 sothat it was evident that the supposed new species was 

 nothing more than the young of Cephalophus dorsalis. In 

 the Book of Antelopes we consequently find C. hreviceps 

 registered under the heading dorsalis. Our Rotterdam-spe- 

 cimen, now stuffed in our Museum, being a very adult 

 one, as the molars show, cannot belong to C. hreviceps 

 — being a young dorsalis — and being quite distinct in 

 size and distribution of colors from all other described 

 allied Antelopes, I am obliged to conclude that it is a new 

 name that it wants : so I will describe it in a few lines as 



Cephalophus leucochilus. 



It is a much stronger and larger animal than dorsalis, and 

 generally darker colored than that species; moreover I exhibit 

 the following differences: upperlips rather high up towards 

 the back of the nose pure white, of the same color is the 

 whole underjaw and the chin, and also a large spot above
