As we have already stated, this form, although otherwise agreeing in nearly every point with the Brindled Gnu, is readily distinguishable by its white mane, white jaw-tufts, and the generally paler colour. But whether we ought to classify it as a separate species, or as a subspecies, or only as a variety of the Brindled Gnu future researches only can decide. We know as yet too little of its exact range and mode of occurrence to be able to settle this question, nor is there a sufficient series of specimens available. If it should be found hereafter that beyond a certain boundary in Eastern Africa all the Gnus met with are of the White-bearded form, and that along this line of junction there are transitional forms between this and the ordinary Brindled Gnu, we should do well to allow it merely subspecific rank. If, on the other hand, it shall be found that the White-bearded Gnu occurs side by side with the Brindled Gnu without mixing or interbreeding with that animal, we shall have to count it as a full species. [Illustration: Fig. 14. Skull of _Connochætes albojubatus_, ♂.] Thomas, in 1892, based his _Connochætes taurinus albojubatus_ on a head in Mr. F. J. Jackson’s collection, at that time under the care of Messrs. Rowland Ward and Co., but since kindly presented by Mr. Jackson to the National Collection. Thomas, from erroneous information, gave the locality as “Uganda,” but we have since ascertained that this and another specimen, still in Mr. Jackson’s possession, were obtained on the Athi plains north of Kilimanjaro. Mr. Gedge assures us that no Gnus at all were met with by Mr. Jackson and himself in Uganda. Mr. Gedge has kindly supplied the following notes on his experiences with the Gnus of British East Africa:--
