line of their advance, and causing considerable 
anxiety to farmers, whose flocks of sheep 
and goats are sometimes swept away by the 
migrating springbucks. In former years the 
migration of these antelopes in countless 
thousands from the deserts of Namaqualand 
to the countries farther south was a common 
occurrence, an unerring instinct guiding the 
wandering herds to districts where rain had 
lately fallen and caused a new growth of | 
green grass. The animals composing these 
migrating herds were called by the Dutch 
settlers of the Cape Colony ‘“ Trekbokken,” 
or “ travelling-bucks.” 
Two other antelopes, the DIBATAG and 
the GERENUK, are included in the present 
group; but both, whilst typically gazelline 
in certain respects, differ so much in other 
ways from all members of that group that 
each has been placed in a separate genus. 
The DIBaTaG is a very remarkable- 
looking antelope, only found in certain

Inhabits Dongola and Senaar 
districts of Central Somaliland, where it was first discovered by Mr. T. W. H. Clarke in 1890. 
This species shows the face-markings of the gazelles, whilst the horns, which are only present 
in the males, much resemble in shape those of a reedbuck. They are rather short, attaining 
a length of only 11 or 12 inches, and their basal halves are strongly ringed in front. 
The neck of this antelope is singularly long and thin, and the tail, which is held curved 
forwards over the back when the animal is in motion, is also much elongated, and only tufted 
at the tip. The dibatag frequents sandy ground sparsely covered with low thorn-bushes,

and lives in small families, being usually met 
with in twos or threes, whilst it is rare 
to find more than four or five consorting 
together. 
The GERENUK, like the last-named animal, 
is an East African species, but has a more 
extended range, being found all over Somali- 
land, and thence southwards to the Tana 
Valley and the Kilimanjaro district of British 
East Africa. The most remarkable external 
characteristic of this species is the exces- 
sively long neck. The males alone carry 
horns, which attain an average length of 
I2 or 13 inches, and, though somewhat 
gazelle-like in shape, are more strongly 
crooked forwards at the points. The skull 
of this species is more dense and solid in 
structure than in the true gazelles, and the 
cheek-teeth are smaller in size. 
Coming now to the Sable Antelope 
group, we find an assemblage of antelopes 
which are all of large size and handsome 
appearance, and in all of which both the
