THE MOUNTAIN NYAI.A. 349 



and skull of a second male of the same species, and also the skulls 

 and horns of two other, and apparently younger, individuals of 

 this sex — all being members of the herd from which the type 

 specimen was obtained. Nor is this all the available material ; 

 for Mr. Allbright had likewise shot a fine old buck out of the same 

 herd, of which the skull and skin were brought home, the head 

 being mounted and the body-skin preserved fiat. All these 

 specimens, thanks to the courtesy of their respective owners, I 

 have had full opportunities of examining. It should be added 

 that, according to Mr. Buxton, the females of the new species are 

 coloured like the males and are devoid of horns. 



The second head brought home by Mr. Buxton and the complete 

 skin belonging to his companion represent darker-coloured and 

 apparently older bucks than the type ; and after seeing these 

 specimens I came to the conclusion that the Sahatu Antelope is 

 nearer to the Nyala than to the Kudus. This opinion is recorded 

 in the ' Field' of October 22nd, 1910 (vol. 116, p. 798), where I 

 definitely stated that the species ought to be known as Tragelaphus 

 huxtoni. Finally, in the recently published sixth edition of 

 Mr. Rowland Ward's ' Records of Great Game ' I have suggested 

 the name Mountain ISTyala as the popular designation of the 

 species. 



That the type specimen, which is a male, and stands, as 

 mounted, 4 feet 4| inches at the withers, represents an Antelope 

 belonging to the Kudu and Bushbuck group is self-evident, and 

 further w^ords on this subject are therefore superfluous. Kudus 

 and Bushbucks are admittedly near relatives ; and the main 

 distinction between the two is to be found in the characters of the 

 horns. In adult bucks of both species of Kudu the hind surface 

 of the basal portion of the horns is rounded and devoid of an 

 external ascending keel, although there is a well-marked front or 

 inner keel. The horns of Bushbucks, on the other hand, have a 

 pronounced keel at the back of the basal portion, in addition to 

 which is a distinct front keel ; and, in consequence, the surface 

 between these two keels is flat, instead of round. This flattened 

 intercarinal surface is, in fact, continued nearly to the summit 

 of the horn, forming a spiral round the axis. In adult Kudus a 

 second keel is developed higher up on the horns, and such a 

 flattened surface consequently exists only near the tip. In the 

 horns of a young Kudu, on the other hand, there is a second keel ; 

 and it follows that the horns of the adult may be compared to 

 Nyala horns with an additional basal portion devoid of a second 

 keel. This shows that the distinction between Strepsiceros 

 and Tragelaphus is very slight indeed. 



Kudu-horns are, however, distinguished from those of the Bush- 

 buck group by their open, corkscrew- like spiral of three complete 

 turns, those of Bushbucks never having more than a couple of 

 such turns. 



In Kudus the males and females are alike in colour, or nearly 

 so, the coloration on the body consisting of vertical white stripes,
