806 ON MAMMALS FROM NOBTH-EASTERN AFRICA. [Nov. 20, 



of hairs at the base of the horns in all of them, and that there 

 was no lateral stripe iu specimens of any age. 



The presence of the boss from which the tuft of hair grows up at 

 the base of the horns is of course normally a character of youth, 

 and is especially marked in the youthful type of G. g.petersi figured 

 by Peters '. In the present case, however, this character is kept until 

 old age (just as happens in the Beedbuck), for not only is the type 

 skull fully adult, as shown by the teeth, but Capt. Ferguson's 

 Lumian skull is quite aged. Yet both clearly show the boss, and 

 have the horns sloping back away from it. 



The characters and ranges of the four subspecies of G. granti 

 that I should recognize may be briefly epitomized as follows : — 

 G. granti typiea. — Horns long, more or less lyrate. Lateral 

 stripe present in youth. Pygal band well-marked. White 

 on top of rump passing right over root of tail. — Interior of 

 East Africa, from the Boran Galla country to Fgogo. 

 G. q. petersi. — Horns more parallel. Colour of back passing on 

 to tail, and dividing the white rump-patch. — Coast districts 

 of East Africa. 

 G. g. smithi. — Horns shorter. No lateral stripe at any age. 

 Pygal band very small. "White of rump undivided. Growth- 

 boss of horn retained to adult life. — Country between Lake 

 Eudolf and Nile. 

 G. q. notata. — Eur comparatively long. Lateral markings and 

 pygal band very strong and black. — Hill-country S. and S.E. 

 of Eudolf. Loroghi Mts. (Neumann) ; Turquel (Ferguson) ; 

 Gessima (Delamere).

a. 6. 90 miles E. of Lado, on 4° 40' N., 20 Feb., 1900. (134.) 

 This is the most northern point from which G. thomsoni has been 

 recorded.

These specimens show that the Bushbuck of the Upper Nile, 

 to which Heuglin gave the provisional name of Tragelaphus bor 2 , 

 and which is referred to in the ' Book of Antelopes ' 3 under T. decula, 

 is really a tenable subspecies of T. scriptus. The following is a 

 description of Dr. Doualdson Smith's specimens : — 



Female more abundantly marked than male. Neck well-haired, 

 not mostly short-haired as in T. s. fasciatus. White markings of 

 limbs well-developed as usual, not obsolete as in T. delamerei *. 



Male. General colour of back pale brownish. Dark nuchal line

* The type of T. delamerei, Pocoek, proves, on the recovery of its skull, 

 which had been mislaid, to be quite young ; not subadult, as was stated in the 

 original description.
