Capt. Swayne, in his well-known work on Somaliland and its wild animals (from which, by the kind permission of Messrs. Rowland Ward & Co., the publishers, we have been allowed to borrow illustrations of the heads of both sexes of this Gazelle), tells us that the “short-coated, light-coloured Lowland Gazelle” carries rather longer horns than those of the Plateau Gazelle (_Gazella spekei_), which are “shorter, thicker, more curved, and better annulated.” “The habits of both,” he continues, “are nearly alike; they go in moderate-sized herds of from three to ten, and resort mostly to stony or sandy undulating ground or ravines thinly dotted over with mimosas. Both species are fond of salt and do not require water. It is hard to understand what they can pick up to eat in the wretched ground which they frequent. They have a curiosity which amounts almost to impudence, but are wonderfully on the alert, and hard to shoot, seeming to know perfectly well the range of a rifle, and presenting but a very small target.” Capt. R. Light, writing to Sclater in 1892, tells us that when he visited Somaliland in 1891 he found this Gazelle between Berbera and Zeila, close down by the sea: “they were often observed feeding side by side with camels and flocks of sheep and goats. When startled they move off the ground in a quick trot, taking bounds over any obstacles and finally breaking into a gallop.” [Illustration: Fig. 65.

Mr. Pease, who has kindly supplied us with notes on this Gazelle as well as on the preceding species, writes that Pelzeln’s Gazelle is essentially the species of the maritime plain and could be seen within shot of the town of Bulhar when he was there in 1896, and within a mile or so of Berbera. “In life it appears of a light rich yellow-buff in colour, with the usual Gazelline marks rather faintly indicated. Its coat is short and fine, and its horns are straighter and longer than those of _G. spekei_. The horns of the female are weak and almost smooth, like those of Speke’s Gazelle.” “Within fifty miles of the sea-shore,” he continues, “this Gazelle is exceedingly numerous in suitable places. Half-a-dozen herds may be often seen at a time, but I have seldom observed more than twenty in a single band. In size _G. pelzelni_ is larger than _G. spekei_, the average height being about 25 inches, while the weight of the carcase is usually a little over 40 lbs.” Mr. D. G. Elliot, who made a successful expedition to Somaliland in 1896, for the purpose of obtaining specimens for the Field Columbian Museum of Chicago, gives us the following account of his experiences with the present species:--
