frei LE BELLIED DUIKER: 
CEPHALOPHUS LEUCOGASTER, Gray. 
Cephalophus leucogaster, Gray, Ann. Mag. N. H. (4) xii. p. 43 (1873) ; Thos. P. Z.S. 
1892, p. 420; Lyd. Horns and Hoofs, p. 211 (1893). 
Size medium. General colour dull chestnut-rufous, with a black dorsal 
band. Face rufous, darker down the centre; crest mixed rufous and black. 
Nape browner. Dorsal stripe commencing in front of the withers, not pure 
black, but grizzled with rufous, and not at all sharply defined laterally ; 
posteriorly, however, on the tail it becomes abruptly very narrow and sharply 
defined, not covering the whole breadth of the tail, but bordered on each side 
with rufous or white. End of tail with a large mixed black and white tuft. 
Under surface of body from chin to anus, inner sides of forearms and hips, 
and also a line passing down the anterior side of the metatarsi, whitish or 
pure white ; no trace of a darker sternal patch. Posterior faces of buttocks 
also pure white, very different from the deep chestnut of this part in 
C. dorsalis. 
Horns of type (apparently 2 ) conical, sharply pointed. 
Skull, so far as can be gathered from a young and very imperfect example, 
with a slender narrow muzzle like that of C. dorsalis castaneus, quite unlike 
the short conical one of C. d. typicus. 
Dimensions of the type (an immature specimen):—Height at withers 
15 inches, ear 2°5, hind foot 7:9. 
Hab. Gaboon. 
The White-bellied Duiker is another discovery of Dr. Gray’s, made, as 
in the case related in the former article, on a specimen obtained from 
the interior of a stuffed example of Tragelaphus euryceros, received from 
Y 2
