“In my journey I first saw _Dibatag_ between Bair and Kirrit. They appear to be scattered all over the country between Bair and Hodayu, and I found them most plentiful about 25 miles from Kirrit. There Wellby shot three and wounded a fourth in one day, but, as a rule, I saw two or three each day in a march of about 20 miles. “Travelling eastward from Hodayu they gradually appeared to grow less plentiful, and the last record I have of having seen one was about 150 miles from Hodayu. After this I saw no more until between Dagha Dalola and Mudug, about 130 miles from the former, in the Mijourten country. Here I was surprised to find them again very plentiful for three days, and I saw a few on the following three days, after which they again ceased. A week afterwards I found them again plentiful in the Marehan country, gradually diminishing in numbers as we travelled south; the last I saw was about 40 miles before we struck the Webbe Shebeyli. On the homeward journey I came across an odd pair now and then in the south of the Ogaden country. I have marked very roughly (see map, fig. 84) the belts within which I found them most plentiful. I do not remember having seen more than eight together. In the Mijourten and Marehan country I have found them quite close to Barao, and most plentiful in country where there was very good grazing of ‘gillop,’ ‘jalaalo,’ and a fine feathery grass. The country between Bair and Hodayu resembled the Haud. As regards the description of the _Dibatag_, I can add nothing to that contained in Swayne’s ‘Seventeen Trips in Somaliland.’” [Illustration: Fig. 84. Map of Somaliland (showing the localities of the Dibatag).] The specimens of _Ammodorcas clarkei_ in the British Museum consist of a head-skin with its skull from Burao Wells, presented by Mr. T. W. H. Clarke (the type of the species), and a stuffed male, the skins of a male and two females and their skulls from the same district, obtained in his second expedition, and presented by the same donor. There are also a skin and skeleton of a female from Darror Wells, on the Haud, presented by Mr. Ford G. Barclay, and the skull of a male from near the Bur Dap Mountain, Central Somaliland, presented by Col. A. Paget. Our illustration of the male of this Gazelle, with the female in the distance (Plate LXXIII.), has been drawn and put on the stone from the specimens in the British Museum. [Since this was written we have received from Dr. Matschie, through Herr Oscar Neumann, the interesting information that the Dibatag occurs in the Kilimanjaro district of German East Africa, a considerable extension of its previously known range.] _September,_ 1898.
