GAZELLA ISABELLA. 
347 
“ The spoor of the trapped Gazelle with the marks of the swinging stick are 
easily found, and the animal tracked down until in sight, when a trained greyhound 
will soon catch and hold it until its master comes up. 
“ During November and December the Gazelles are caught when fawns by trained 
hounds, and this is the simplest method ; but it can only be practised during two 
months, as it takes a very good dog to catch a Gazelle when more than this age. 
“ During the eight days I was in the desert, though unsuccessful in trapping any, 
I saw several very fine specimens of Loder’s Gazelle.”— W. E. be W .

Height at withers about 25 inches. General colour pale fawn, rather variable in 
tone, sometimes tending towards brownish. Light lateral band very indistinct; dark 
band generally fawn like the back, occasionally darker, almost smoky brown. Central 
dark facial band deep rufous, a darker nasal patch often developing in old individuals. 
Light facial streaks well defined, white. Pygal bands almost obsolete, little or not 
darker than the back. 
Horns of the male nearly straight and parallel for a short distance, then evenly 
diverging and curving backwards for four-fifths of their length, the tips strongly bent 
inwards nearly or quite at a right angle; length about 10 inches. ihe female 
is similar to the male, but the horns are slender, scarcely ridged, their tips curved 
inwards rather than upwards, and nearly equal to those of the male in length. 
Hah. Coast-lands of the Led Sea from Suakin to Massowah, and over the interior to 
Bogos, Barca, and Taka. 
Capt. Stanley Flower writes:—“ G. isahella appears to be the common Gazelle 
from No. 6 Station (between Wadi Haifa and Abu Hamed) right away to Khartum. 
I have seen no G. dorcas south of Wadi Haifa, but the Gazelles from that place I 
believe to be G. dorcas.” 
Dr. Anderson had a note relating to this species, saying that behind Suakin the 
Gazelles were not to be seen far out on the open plain, as they usually kept close to 
the base of the hills.
