1896.] MAMMALS OF NYASALAND. 797 
head and body 635 millim.; tail without hairs 25; ear-opening 
(in wet state) 87x 60. Horns, length anteriorly 31; basal carcum- 
ference 39. 
Type. B.M. No. 96.10.26.3. 
This very beautiful little Antelope forms an interesting con- 
necting link-between the Grysbok and the Steinbok, which it has 
been sometimes thought might be placed in different genera, owing 
to their difference in hoof-structure. In the latter important 
respect R. sharpe: agrees with the Steinbok, having no supple- 
mentary hoofs, but in the presence of the white hairs in its coat it 
resembles the Grysbok, while its horns are equally different from 
both its allies. 
If the type is an adult specimen (and its digital epiphyses are 
already closed), the horns are shorter in proportion than in any 
other species of the group, but even if not, their great thickness 
and conical shape would readily distinguish them from those of 
any other known species. 
Mr. Sharpe is to be congratulated on his discovery of this hand- 
some little species, and will, we may hope, soon send home 
further specimens of it, accompanied by their skulls.

a. Imm. 2. Senga Valley, Upper Loangwa R. Presented by 
Mr. R. Crawshay. Type of species. 
This interesting animal, the representative in the Senga 
Valley of K. vardoni, from which it differs in its smaller size, is 
fully described in the ‘ Book of Antelopes’ (ii. p. 145) and only a 
passing reference to it is here necessary.

Lake Mweru (A. Sharpe). 
The Mweru Reedbuck has a well-marked black patch on the 
crown between the horns. Similar patches have been noticed by 
Gray in 8. African specimens.
