216 LIVINGSTONE'’S ELAND © CHAP. , 
swampy country affected by many. 7. gratus and 7. spekei are 
larger forms; the Boschbok, 7. sylvaticus, is smaller. 
The Kudus, genus Strepsiceros, have more markedly twisted 
horns, which are absent in the female. The body is vertically 
striped with white. The largest species is S. kudu; a smaller 
form, S. imberbis, is from Somaliland. 
The last genus of this section or sub-family is the African Eland, 
genus Oreas ' (which it appears should be spelt Orias). The Elands

are perhaps more Ox-like in appearance than the other members of 
this group, and in both sexes have horns, in which the spiral 
twisting is more close. Ovias canna is the name of the common 
Eland. 0. livingstonit has been applied to an East African 
variety, which has thin and faint lateral stripes like the other 
members of the group to which it belongs. 
The genus Boselaphus includes only B. tragocamelus, the 
Nilgai, which is purely Indian in range. The female is hornless, 
and the horns of the male are smooth and not long. 
1 Taurotragus oryx has unfortunately been discovered to be the correct name 
for the Eland.
