agrees in its comparatively small, straight, and upright horns, 

 whereas in point of size and in several structural features 

 it comes nearer to the latter. In the Rhebok the male only is 

 furnished with horns ; and there is no gland below the eye, 

 although there are small lateral hoofs to the feet. Rhebok 

 inhabit the hilly districts of South and South-East Africa, and 

 much resemble Chamois in their general habits. They are usually 

 found in parties numbering from six to twelve ; but are now much 

 less abundant than formerly. 



Reedbucks. The South African Reedbuck or Reitbok, Cervicapra g^est 



Genus arundinum (1214, fig. 26), is the typical representative Q^ses II 

 Cervicapra. of the Cervicaprine section of Antelopes, or Cervi- & III.] 

 caprince, which includes medium-sized, or large species, with naked 

 muzzles, and narrow, goat-like upper molar teeth. On the face the 

 glands below the eyes are either rudimentary or wanting, bat the 

 skull has frequently unossified spaces in this position, as well as pits 

 on the forehead, and there may be glandular patches below the ears. 

 From the other members of the group, Reedbucks, of which there 

 are several species, are distinguished by their comparatively small 

 and forwardly-curved horns, and the rather short and very bushy 

 tail. They have also a bare glandular patch below the ear. The true 

 Reedbuck, which ranges to the Bahr-el-Ghazal, generally associates 

 in pairs, and was formerly abundant on open, grassy, or reedy valleys 

 traversed by streams. Although never found far away from water, 

 these Antelopes keep to dry ground when hunted, and do not 

 seek protection by venturing into boggy localities. 



The Waterbucks These Antelopes, the largest members of the [CasesIII, 

 and Kobs. Cervicaprine section, are water-loving animals, xiv']^ 

 GenifS CobuS. associating in small herds. Their long and 

 sublyrate horns are ridged nearly throughout their length, and 

 the tail is rather long, and tufted at the tip. Among the larger 

 species are the Common Waterbuck, C. ellipsiprymnus (1218), of 

 South Africa, distinguished by the white elliptical ring on the 

 rump, the Sing-sing Waterbuck, C. unctuosus, of West Africa, and 

 the closely allied Defassa Waterbuck, C. defassa (1219, fig. 28), of 

 East Africa and Abyssinia. The smaller forms include Mrs. Gray's 

 Kob, C. maria (1220, fig. 30), the nearly related White-eared Kob, 

 C. leucotis (1221)^ of the White Nile, old males of both of which
