many of the specimens of South-African Mammals, as well as to the 
fact that a number of interesting species were not represented at 
all; so Mr. Selous took note of what he ought to obtain should he 
ever revisit the interior. It was not then his intention to do so, 
for, after many years of roving, he felt inclined to take a farm 
and settle down; but Diis aliter viswm, and he soon started on 
another expedition, to be followed by many more during the next 
ten years. Some of the results of his truly scientific collecting may 
be seen in the superb examples of antelopes of various species which 
now adorn the galleries at South Kensington, while other valuable 
animals are in the museum at Cape Town and elsewhere ; though as 
yet the principal object of his search—the adult of the square- 
mouthed Fhinoceros simus, “the largest of modern terrestrial 
mammals after the elephant”—is still wanting in our collection. 
_ We think—for we cannot be sure from the map supphed—that it 
was not far from the present site of Salisbury that Mr. Selous shot 
the two last of this species he saw or ever expects to see, and he 
preserved the head of the male for the Cape Town Museum, counting 
upon procuring a finer specimen for our National Collection later on 
in the season. But in 1886 two Boer hunters got into the little 
tract of country where the few white rhinoceroses were left, and 
killed ten of them, five more being killed by the Matabili; and 
although, in August 1892, Mr. R. T. Coryndon shot a female and 
preserved its skin and skeleton, and captured the calf (which after- 
wards died), yet, through some unfortunate mischance, the fact 
remains that this once plentiful species is at present represented in 
collections by an antique calf in our Museum and a single specimen 
at Leyden. 
Mr. Selous was surprised to find the fresh “ spoor” of the hippo- 
potamus at an elevation of upwards of 4000 feet above sea-level, 
but, he adds, “ this animal wanders a great deal in search of food 
when undisturbed, especially during the rainy season.” At a pool 
which offered a favourable opportunity for observation he noted by 
the watch the duration of submersion, and found that after being 
fired at a hippo’ could stay down four minutes and twenty seconds, 
though from two to two and a half minutes was the usual time ; 
and, as illustrating the supposed great age of Africa, he mentions 
‘the hippopotamus paths worn deep into the solid rock along the 
Lower Umfuli River, formed in the hard stone, with the central 
ridge plainly shown as in a hippopotamus path made but yesterday 
in muddy ground, proving that the mammals existing in it at the 
present day have roamed the land for countless ages.” With regard 
to the distribution of the wiry-haired klipspringer antelope, he con- 
siders it worthy of remark that in Mashunaland this small active 
species is to be found along the courses of all the larger rivers, 
amongst boulders and masses of rock ; whereas in Cape Colony the 
species is confined to the highest portions of the most rugged hills 
and mountains, where the snow often les deep. On one occasion
