658 DR, J. KIRK ON THE MAMMALS OF ZAMBESIA. [Dec. 13, 
about the Chobe and Zambesi, in the centre of the continent, but else- 
where as yet unknown. With the H. leché it often mixes, the habits 
of the two being very similar, the “‘ Poku” being less aquatic and 
found more often on dry ground. It is known by its smaller size, 
its more erect carriage, and plumpness of neck. The horns are less 
turned backwards, and partake more of the aspect of the “‘ Reit-bock.”” 
Our specimen of the horns was lost while travelling to the coast. 
57. HELEOTRAGUS LECHE. 
Adenota leché, Gray. 
This Antelope has not been found near either coast in the line of 
the Zambesi; it is limited to the central valley above the Victoria 
Falls, to the marsh-banks of that river and its tributaries, especially 
the Chobe. It is a water-antilope, frequenting damp marshy places, 
and taking to impassable swamps, among reeds and papyrus. It 
goes in considerable herds, accompanied by several males, mingling 
often with the “‘ Poku,” another Antelope peculiar to that region. 
In the distance the H. lech? may be known by the peculiar way in 
which it allows its horns to recline back, almost touching the withers. . 
This Antelope was found by Mr. Petherick in the marshy region 
on the Nile, near the Bahr-el-gazal. 
58. HELEOTRAGUS ELLIPSIPRYMNUS (Ogilby), 
« Water-buck”’; “Tumoha” of the Bechuanas; ‘“‘ Nyakobswe ” 
of the Lower Zambesi. 
Very common on the sea-coast at the mouth of the Zambesi and 
Rovuma, and in all damp plains crossed by rivers or near lakes ; but 
absent from mountains. When wounded, it makes for the water or 
for the dense shade of reeds. Goes in herds of about five to fifteen 
females followed by one or two males. In the rutting-season severe 
fights take place between rival males. Near the sea-coast the flesh 
is well-flavoured and juicy, in the interior dry and worthless. Like 
all water-antelopes, the Waterbuck is very tenacious of life. Shot 
through the lungs, they will make off for some distance; shot in 
the belly, they are seldom seen again ; and with a Jacob’s shell burst 
behind the heart, they have been known to run twenty paces. 
The three genera Heleotragus, Adenota, and Kobus are most inti- 
mately related, forming together a single tolerably well-defined and 
natural genus, the subdivision of which is quite artificial and very in- 
convenient. 
59. ASGOCEROS NIGER (Harris). 
Named at Sena “ Para-para.” 
One was found killed by lions on the banks of the Zambesi, at the 
head of its delta; they are found inland from Shupanga, near Mo- 
ramballa, on Lake Nyassa, on the Batoka Hills, and in the plains 
between Linyanti and Sesheke. This is the ‘ Tahetse ”” of the Be- 
chuanas; the ‘ Qualata e enchu”’ of the Makololo, who distinguish 
two species—the “ Qualata e tsetla,”’ or yellow Qualata, and the other, 
which means the black one. One shot on the Batoka Hills was the
