known to the Tnnisian Arabs by the name of Ghazel ahied or 

 liesel ahied, meaning the White Gazelle, its Algerian name lieem 

 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 rejjiaoes 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 

 llegency, 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 

 surroiui dings, 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, ho wovor, wlio are nearly nil spoils- 

 men, kill a good many, and every year some 500 to 000 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 fouud in the sand 

 wastes. The female of G. loderi, according to Spatz, often has two 

 young cmos at a birth, differing in this respect from G. dorats, 

 wliich seems to have but one. 



So good a description of G. loderi has been given by 

 Mr. Thomas (P. Z. S. 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.

(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 Eiver valley — which, as you can 

 see, drains into the Upper Zambesi River, and not into this lake.
