known to the Tunisian Arabs by the name of Ghazel abied or. 
Resél 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. lodert 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 sports- 
men, 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. 
So good a description of G. loderi has been given by 
Mr. Thomas (P. Z. 8. 1894, p. 470), that I can add nothing 
thereto, except it be merely to say that the coat of this Gazelle is 
extremely fine and short-haired, and that in specimens which I 
have the knee-brushes are so slightly developed as to be scarcely 
noticeable or worthy of the name. 
5. On two Collections of Lepidoptera made by Mr. R. 
Crawshay in Nyasa-land. By Arruur G. Burttmr,

(Plates XLI. & XLII.) 
A few days before his return to England a small collection 
of Lepidoptera reached me from Mr. Crawshay, accompanied by 
a letter, in which he stated that it was from quite a new locality, 
“viz. from Senga, the Loangwa River valley—which, as you can 
see, drains into the Upper Zambesi River, and not into this lake.
