Skull with the modification due to the development of a proboscis much more striking than in the first section of the genus, although not carried to such an extreme as in _M. guentheri_. Premaxillæ slender, their upper edge forming an =S=-shaped curve; their ascending process sometimes ending just above the anterior tooth, and sometimes rising nearly or quite to meet the nasals. Nasals very short. Last lower molar with the usual third lobe characteristic of all other ruminants but those of the _M. saltiana_ group. Even here, however, the lobe is very small. Dimensions of a good male example:--Basal length 3·7 inches, greatest breadth 1·95, muzzle to orbit 2·03, muzzle to tip of nasals 1·25. Horns thick, strongly ridged below, seldom exceeding 2½ or 2¾ inches in length. _Hab._ E. Africa from Southern Somaliland to Ugogo. This Dik-dik was likewise first described by Dr. Günther in 1880 from specimens transmitted to the British Museum by Sir John Kirk, who procured them near Brava, on the coast of Southern Somaliland. Dr. Günther drew special attention to the peculiar form of the elongated muzzle in this species. This feature, as will be seen by the illustration (fig. 29), which we are able to reproduce by his leave and that of the Zoological Society, is a prominent character in _Madoqua kirki_, as in the preceding and following species. [Illustration: Fig. 29. Head of _Madoqua kirki_ (P. Z. S. 1880, p. 17.)] The conformation of the skull of this species, as has been pointed out by us above, and previously much commented upon by Dr. Günther, is another noteworthy peculiarity. It is shown in the two illustrations (figs. 29 _a_ and 29 _b_), for the use of which we are likewise indebted to the Zoological Society and Dr. Günther. [Illustration: Fig. 29 _a_.
