" Klipspringeis exist in small numbers among the rocky hills 

 and ravines in the vicinity of the Augrabies Falls, and may 

 becon\e more numerous in the hill country still further west. 



A pair were put up on one of the islands near the Falls, which 

 crossed over a shallow branch of the river to the mainland when 

 hunted. 



I have heard of no other locality eastwards along the river 

 between the Falls and Upington where they occur, although they 

 are said to reappear near Prieska. 



The hair of Klipspringers was formerly much in demand among 

 the Boers for stuffing saddles. 



Apparently — apart from stragglers — the only other resident 

 buck occurring near the river is the Steinbok, A single indi- 

 vidual was observed about twelve miles south of Louisvale. 

 They are well known locally, although not considered plentiful." 



33. Hippopotamus amphibius L. 



204. Incisor picked up from bed of river near Upington. 



" The portion of a tusk sent was picked up in the bed of the 

 Orange River near Louisvale, and presented by Mr, D. Biggs. 



Although Hippopotami have long been extinct above the 

 Augrabies Falls, fragments of tusks are not infrequently picked 

 up in or near the river bed. 



A small school of Hippo are said to exist in the lower reaches 

 of the Orange River, but as this is a very uninhabited region few 

 authentic reports are available about them. 



Cornell, in his fairly recent book, 'The Glamour of Prospecting,' 

 mentions having seen them, so that there is every reason to believe 

 they are still there."

 near Upington ; although a skull was picked up on a large isolated 

 kopje about twelve miles to the south of Louisvale. 



Diurnal ; but during the hot weather seldom showing them- 

 selves except during the early mornings and evenings."
