Mr. Pease also points out that in the “Rhime” the horns in their main outline form a long evenly tapering V, whilst in the Admi the horns are more inclined to be parallel, and towards the points usually take an inward and forward turn, as shown in the diagrams (Fig. 66, _a_, _b_) which by the kindness of the Zoological Society we are able to reproduce. The annulations, also, Mr. Pease states, are deeper and more marked in the Admi, and stop more abruptly towards the points than in the “Rhime.” [Illustration: Fig. 66. Diagram of horns of Rhime (_a_) and Admi (_b_). (P. Z. S. 1896, p. 814.)] This Gazelle occurs also in Southern Tunis, as we learn from Mr. J. S. Whitaker, F.Z.S., who has written the following notes on it in the Zoological Society’s ‘Proceedings’:-- “This pale desert Gazelle is known to the Tunisian Arabs by the name of ‘Ghazel abied’ or ‘Resêl abied,’ meaning the White Gazelle, its Algerian name ‘Reem’ or ‘Rim’ being apparently unknown in Tunis. “It seems to be a true desert species, never occurring out of the sand-dune country, where it replaces _G. dorcas_; and while the home of the latter species is the semi-desert country, with its vast stony plains, covered with scanty scrub vegetation, the habitat of _G. loderi_ is undoubtedly the more arid region of sand wastes further south. “Herr Spatz, who has resided for several years in the south of Tunis, and is well acquainted with this Gazelle, informs me that it is common in the inland country of the extreme south of the Regency, being first met with at about 25 to 30 miles south of the Chott Djerid. In the districts where it occurs it is plentiful, and is generally to be found in small herds; but owing to its very pale colour, which harmonizes so well with that of the desert surroundings, it is not easily distinguished at a distance, and being, moreover, extremely shy and wary, a near approach is not often possible. The nomad Arabs, however, who are nearly all sportsmen, kill a good many, and every year some 500 to 600 pairs of horns of this species are brought by the caravans coming from the interior to Gabes, where they find a ready sale among the French soldiery. “Herr Spatz confirms what Sir Edmund Loder says of this species never drinking, and, as to its food, says it subsists on the leaves and berries of the few desert plants to be found in the sand wastes. The female of _G. loderi_, according to Spatz, often has _two_ young ones at a birth, differing in this respect from _G. dorcas_, which seems to have but one.
