unwittingly driving him before me along the bank of the river. He trotted like a 
roebuck into the thick cover and then stood broadside among the thorn bushes. I 
sprang from my saddle, and guessing about his position, I fired and missed him; he 
then trotted along a rhinoceros’s footpath, and gave me a second chance. Again I 
fired, and before my rifle was down from my shoulder the Serolomootlooque lay prostrate 
in the dust. The ball had cut the skin open along his ribs, and entering his body had 
passed along his neck, and had lodged in his brains, where we found it on preparing 
the head for stuffing. I was not a little gratified at my good fortune in securing this 
novel and valuable trophy; he was one of the most perfect antelopes I had ever 
beheld, both in symmetry and colour. I had him immediately conveyed to camp, 
where I took his measurement, and wrote out a correct description of him for the 
benefit of naturalists. I christened him the ‘ Antelopus roualeynei, or ‘ Bushbuck of

the Limpopo. 
It is not, however, without considerable hesitation that we have decided 
to retain Cumming’s name for the form of Bushbuck that, as will be presently 
seen, extends from the Limpopo River northwards to British East Africa and 
Somaliland. Although, according to Selous, the Bushbucks that are found on 
tne Zambesi to the east of the Victoria Falls differ from those inhabiting the 
Limpopo (that is to say, from the typical rowaleyni) in being of a dark red 
colour, thickly spotted on the haunches, shoulders, and sides, and marked 
with three or four faint white stripes, whereas the adult of the Limpopo form 
is a dark brownish grey, not striped, and often without a sign of spots, we 
venture to think there is sufficient evidence to show that these distinctions 
will not hold good when more material from the two rivers has been 
examined. For example, a fine series of skins of bucks of various ages sent 
by Sir Harry Johnston from Nyasaland, and presumably identical with the 
form observed by Selous on the Lower Zambesi, shows considerable variation 
in colour. The young male is yellowish red throughout, with about half-a- 
dozen spots on the hind-quarters and scarcely a trace of stripes. The adult 
is of a richer yellowish red, brighter on the hind-quarters, and passing into 
black on the shoulders, belly, and base of the neck, with a few white spots 
on the hind-quarters, and occasionally also on the shoulder, and sometimes a 
row of spots along the sides above the belly. Sometimes there are about 
three indistinct white stripes on each side, sometimes only one; but more 
often there are no traces of them to be seen, the presence or absence of the 
stripes being apparently independent of age. As we pass northwards into 
East Africa from Nyasaland the stripes, judging from accounts given by 
sportsmen and naturalists, seem to become more persistent, and in a mounted 
example in the British Museum, obtained on Manda Island, opposite Witu,
