The Natal Duiker, which is perhaps a southern representative of the. 
next species, is, like it, of a nearly uniform bright bay colour, rather 
paler below, and with some inconspicuous darker markings on the vertical 
crest. Our figure of this species (Plate XVI.) was put on the stone by 
Mr. Smit from a sketch prepared by Mr. Wolf, and was probably taken 
from one of the specimens in the British Museum; but of this, we regret 
to say, there is no certain record. 
The discovery of the Natal Duiker is due to Sir Andrew Smith, who met 
with it in the forests of Natal and first described it in 1834 in one of his 
articles on African Zoology published in the ‘South African Quarterly 
Journal.’ Sir Andrew afterwards figured it in the volume of Mammals of 
his ‘ Illustrations of South African Zoology,’ where the following notes are 
given on its habits :—‘* Both C. cwruleus [=C. monticola, nob.| and C. nata- 
lensis inhabit the African forests; the former towards the Cape of Good 
Hope, the latter to the eastward about and beyond Port Natal. They both 
feed partly upon the grass which occurs among the underwood, and partly 
upon the young leaves and shoots of the brushwood and small trees which 
exist in the situations they inhabit; and to obtain the latter they may 
occasionally be seen scrambling among shrubs, or ascending the stems of
