4.. Supplemental Note on the Distribution of Loder's 

 Gazelle and the Dorcas Gazelle in Algeria. By Alfred 

 E. Pease, M.P., F.Z.S. 



[Eeceived April 4, 1899.] 



I find that a previous paper which I contributed on the Antelopes 

 of Algeria (see P. Z. 8. 1896, p. 809) requires correcting in some 

 important particulars, especially in respect of the distribution of 

 the Dorcas and Loder's Gazelle. Before deahng with the question 

 of their distribution I might supplement what I have already 

 written as to the names by which these different species are 

 distinguished by the Arabs. In the North-eastern part of the 

 Algerian Sahara the Dorcas Gazelle (Gazella dorcas) is generally 

 known simply by the name " Rhezal "' or " Ehezal es sahara," the 

 gazelle of the desert, iu contradistinction to " Bhezal el djebel," the 

 gazelle of the mountain (the Admi or Edmi, G. euvieri). In the 

 neighbourhood of the Oued Djedi and Bou Saada the Dorcas is 

 called " senny," in the Central Sahara it is called " swain." A 

 buck of any species is called " atrous." Till my last journey this 

 year I have always spelt the Arab name for Loder's Gazelle 

 (G. loderi) " Ehirae," but I think this is not so phonetically correct 

 as Sir Edmund Loder's speUing, " Eeem." The Arab word is 

 spelt with the three Arabic letters ra, ia, mim, which reduced to 

 English letters would be " rym " or " rim " and pronounced " reem." 

 The description of the range of both the Dorcas and Loder's 

 Gazelle requires correcting. In the first place, the Dorcas is not 

 restricted to any such belt of desert as the first 100 miles or so 

 south of the Atlas range. It is to be found on the smaller deserts 

 north of the last ranges of the Atlas. This last winter I saw 

 them and got one specimen from the country south of the Chott 

 el Hodna and north of Bou Saada, a district known to the 

 French locally as the Little Sahara. I found the Dorcas Gazelle, 

 after crossing the Oued Djedi, all the way to the Mzab, in 

 the Mzab between the Mzab and Ouargla, and south and east of 

 Ouargla. It is to be found in the Central Sahara in the Touareg 

 Country and in the neighbourhood of Ghadamis. Wherever 

 the country is not purely sand-desert, and vi'here immunity from 

 .. molestation and suitable vegetation allow it to live, it is to be 

 met with ; and even in the purely sand-desert south of Tougourt 

 and near the Oued Ighaghar I found it in small bands. In the 

 sand-desert between Ouargla and the Erg, where I expected to find 

 only the Eime, and in the region of the Gantaras between Hassi 

 Tafaya and the Oued Ighaghar, I found it often on the same 

 ground as the Eime ( Gazella loderi). From my own observation 

 and from the information I picked up from my Chaambi hunter 

 and guides, I feel convinced that though the Dorcas travels often 

 into the sand-desert, the Eime never quits the sand-country for 

 the stony deserts, though I have of course seen the Eime on the
