and uniting across the base of the tail, so that the latter is quite separated 
from the dark body-colour ; laterally the white penetrates angularly into the 
body-colour, overhanging the top of the pygal band, which is generally well- 
defined. Outer sides of limbs fawn, without blacker markings. Knee-brushes 
present, dark fawn. ‘Tail above white for its basal half; black and crested 
terminally. 
Skull stout and heavy, nasal opening broad. In that of an adult male the 
basal length is 9°75 inches, greatest breadth 4°4, muzzle to orbit 5:3. 
Horns very long, longer and more powerful than in any other Gazelle ; 
evenly but slightly curved backwards below, and gently recurved forwards — 
terminally ; sometimes but slightly divergent, but more often, especially in 
specimens from Kilima-njaro, they spread widely above, approaching each 
other again at their tips. Their section at base is a long oval, very different 
from the nearly circular section found in G. soemmerringi. 
Female. Similar to the male, but the horns slender, nearly circular in 
section, more strongly ridged than in the females of most Gazelles; about 
two-thirds in length of those of the male. 
Hab. Eastern Africa, from the district of Lake Rudolph, southwards to 
Ugogo. 
Grant’s Gazelle, which has been appropriately named after one of its 
discoverers, is pre-eminent, even in this ornamental genus, for its size and 
elegance, and is, in fact, generally allowed to be one of the most beautiful 
species of the whole group of Antelopes. Speke and Grant left Zanzibar on 
the well-known expedition during which the efflux of the Nile from Lake 
Victoria was discovered, in September 1860. Starting from Bagamoyo on the 
opposite coast, and passing through Usagara, they arrived about two months 
later in Ugogo, then under the rule of a native chief called Magomba. It 
was in December 1860 during their stay at this place, where they were long 
detained by the drunken chief and his wazir, that Speke first met with the 
present Antelope. In the ‘ Journal’ of his travels Speke tells us that while 
kept waiting to arrange the amount of his “ hongo” he took the time out in 
the jungles very profitably, “killing a fine buck and doe Antelope of an 
unknown species.” “These animals,” he continues, “ are of much about the 
same size and shape as the common Indian Antelope, and like them roam 
about in large herds, the most marked difference between the two being in
