probably by waiting for them at favorite places. The measurements of the larger 
are: total length 1050 mm., tail 100, hind foot 250, ear 87, height at shoulder 520. 
Cephalophus maxwelli liberiensis Hinton. Gray Duiker; ‘‘Gazelle”’ 
Cephalophus liberiensis Hinton, Ann. Mag. Nat. Hist., ser. 6, vol. 9, p. 530, 1920: Mount Barclay, 
Liberia. 
Size medium, standing 14 inches high at the shoulder; general color slaty brown, paler below; 
horns small, the female hornless. Liberia to Gold Coast, and perhaps Nigeria. 
Hinton has lately separated the form of Maxwell’s Duiker occurring from 
Liberia south, from that found from Sierra Leone to the Gambia, on the ground 
that the horns are smaller and present only in the males, while those to the north- 
west have larger horns in the males, and the female is provided with these struc- 
tures as well. Lydekker retains the generic name Guevei for this species. 
This is probably the commonest of the genus in the thickets and forest under- 
growth of Liberia. Bittikofer regarded it as the most plentiful of the duikers, 
and secured specimens from Soforé Place, Buluma, Robertport, and on the Junk, 
Du, and Farmington rivers. Near our camp on the Du, we frequently saw fresh 
tracks of small duikers in soft ground along the edges of bushy thickets or on the 
forest trails. One that we came upon just at daybreak, was standing among low 
erowth at one side of the forest path, watching us intently, but on the instant 
that it was discovered and before a shotgun could be swung into position it had 
scurried away into the thicket. Biittikofer says that the natives trap them in 
foot or neck snares along trails, or shoot them from ambush in a tree or from the 
top of a termite hill. We occasionally came upon places in the forest where a 
duiker had come regularly for many days to deposit droppings, until a consider- 
able pile had accumulated, some old and disintegrated, others fresher, still others 
very fresh indeed. This habit is probably not uncommon among small antelopes 
of various species that live in a circumscribed area. In spite of considerable 
hunting we saw almost nothing of the various duikers, probably because they are 
largely nocturnal or crepuscular in their activities, and because they keep in the 
shelter of dense thickets in the forest or the edges of clearings. Other species may 
occur within the limits of Liberia, such as Cephalophus grimmia campbelliae, 
known from Sierra Leone, orange yellow, profusely dark grizzled, seventeen 
inches at the shoulder. 
Tragelaphus scriptus scriptus (Pallas). Bushbuck, Harnessed Antelope; ‘‘Red Deer” 
Antilope scripta Pallas, Miscellanea Zool., p. 8, 1766: Senegal. 
Larger, standing about 27 inches at shoulder; males provided with horns with a spiral twist; 
colors contrasting, the shoulder, haunches, belly, and a line down the back, black; head short-haired, 
pale rufous, the nape nearly bare; dorsal area bright yellowish rufous, becoming brighter and clearer 
rufous on the rump; about seven transverse white stripes, and a lengthwise one along the sides 
bordering the black belly; several white spots posteriorly between the end of this stripe and the 
last three transverse stripes; two white spots at the knee, a large white spot above each hoof, a 
white stripe down the inner side of hind leg and on lower side of tail. Gambia to Fanti. 
A handsome antelope, this is a frequenter of forest growth, especially open 
thickets along streams. Biittikofer says it is often common in the neighborhood
