812 MR, A. E, PEASH ON THE [Nov. 17, 
The best and strongest horns I know are a pair I purchased 
from an Arab who had come to Biskra vid Ouargla (see fig. 1, p. 811). 
They measure 343 inches in length, 63 in. round the base ; 173 in. 
between the tips, and 123 in. between the horns at the lower 
outward curve. 
he Chambas who have firearms shoot a great many of these 
Antelopes, and assure me that when there is a wind sufficiently 
strong to make the grass, broom (Genista monosperma ?), and 
bushes wave, it is very easy to get them. They told me that they 
could easily take me where they were “like flies,” and where I 
could get as many as ever I wished. 
The Touaregs hunt the Begra el Ouash or “Tamita” with 
Slonghia (Greyhounds—the Saharian Greyhound is called a 
“sloughi” by the Arabs). The sloughia bring it quickly to bay, 
and the men go in and spear it. 
Algeria and the Northern Sahara yield three distinct kinds of 
Gazelles (I know nothing of Gazella rufina). Old works which allude 
to these species are most confusing, and it is often impossible from 
their descriptions and names to know to which their remarks refer. 
Shaw’s accounts, so far as they go, of the wild animals of the 
Barbary States are comparatively clear. In alluding to the 
Gazelles, he says :— - 
“‘ Besides the common Gazelle or Antelope” (i.e. Gazella dorcas) 
“(which is well known in Europe) this Country likewise produceth 
another Species of the same Shape and Colour, though of the 
Bigness of our Roe-Buck and with Horns sometimes of two foot 
long. This the Africans call Lidmee (7.¢. the Admi or Gazella 
cuvieri), and may, I presume, be the Strepsiceros and Addace of 
the Antients ...” 
It is usual to regard the Dorcas as the “common Gazelle,” but 
I have no doubt whatever that the Rhime (G. loderi) is by far 
the most numerous species in North Africa, and to be found over 
a very much more extended area than the Dorcas. The descrip- 
tion given in the ‘ Proceedings’ of this Society (1894, pp. 467-473) 
of the Algerian Gazelles is so complete that I shall confine myself 
to a very brief notice of the three species that I am familiar with. 
(1) The Dorcas (Gazella dorcas), called by the Arabs generally 
“ Rhozal,” but when exactness is required “ Hemar.” They regard 
a large Dorcas as one of a separate race, and he is called Bow 
Khrouma (Large Throat), but the Bou Khrouma and Hemar are both 
alike the Dorcas Gazelle. The French discriminate between the 
Dorcas and the Rhime (G. oder?) by terming the former “ Gazelle 
des Plaines,” and the latter “‘ Gazelle des Sables.” 
It is with great respect and diffidence. that I object to the 
Dorcas being described (see P. Z. S. 1894, p. 467) as ‘the common 
Gazelle of the Algerian Sahara generally,” for the Dorcas is not 
met with in the Sahara proper, so far as I can learn, and in the 
Eastern Algerian Sahara at least is not to be found south of 
lat. 33°. The Dorcas in the Eastern Province and in Tunisia is the 
common Gazelle of the plains immediately south of the Aures
