278 MR. O. THOMAS ON A NEW DIK-DIK ANTELOPE. [Apr. 5, 



appear to iudicate a third race of the species, for which a new name 

 may be subsequently requisite. 



In any case the Mauipur locality is of interest, as being more 

 northerly than any as yet recorded for the species, Blyth suggested 

 that the Banting would be found in the ranges to the east of Chit- 

 tagong, and it is possible that in this district the Manipur form may 

 be found to intergrade with the Burmese race. 



4. Description of a new Dik-dik Antelope {Madoqua) 

 discovered in N.E. Africa by Mr. H. S. H. Cavendish. 

 By Oldfield Thomas^ F.Z.S. 



[Eeceivecl March 22, 1898.] 



Among the sporting trophies collected during Mr. H. S. H. 

 Cavendish's recent adventurous journey into the Lake Eudolf 

 region there are a number of skulls, scalps, and body-skins — 

 unfortunately all separated — of the different species of Dik-dik 

 met with during the expedition. The majority of these, as might 

 be expected, are assignable to M. phillipsi and M. (juentheri, those 

 being the forms most usually shot by Somali sportsmen. 



But one skull and one skin, presumably belonging to each other, 

 are clearly different from the remainder, and iudicate a new 

 species of this group. It may be called 



Madoqua CAVENnism, sp. n. 



Allied to M. kirlii, Giiuth., by the general characters of the skull, 

 by the S-shaped upper outline of the premaxillas, and therefore 

 no doubt by the presence of a third lobe on the last lower molar, 

 but the lower jaw has unfortunately been lost. Size, however, 

 decidedly larger, so that the new form equals and perhaps exceeds 

 M. damarensis, the largest previously known species. The skull 

 is that of a young animal, as the milk-dentition is still in place, 

 but nevertheless its size is just about the same as that of the 

 typical skull of M. damarensis, that of an old female. Nasals rather 

 longer in proportion, and decidedly broader, than in M. hirhii, 

 also broader than and of rather a different shape to those of 

 M. damarensis. Nasal opening very large, conspicuously broader 

 and higher than in either of the allied species. Premaxillse not 

 touching each other in the middle line above, as they do in the 

 type of M. damarensis ; posteriorly they reach to the nasals, 

 articulating broadly with the latter. 



Horns long and thick, heavily ridged ; obliquely oval in section. 



In colour, the skin believed to belong to the typical skull is a 

 dark fawn, much darker than in M. damarensis, on the anterior 

 back, becoming, by the dying out of the fulvous suffusion, more 

 greyish posteriorly, and quite ashy grey on the sides of the rump. 

 Shoulders, ill-defined line along flanks, and front of limbs sandy 

 rufous. Hairs of crest suffused throughout with didl fulvous.
