[4] We are indebted to the authorities of the Smithsonian Institution for a series of measurements of the hoofs of the Kilimanjaro Dik-diks collected by Dr. Abbott. These measurements have helped materially to bring us to the conclusion we have come to above, as their wide range of variation shows that certain differences in the hoof-lengths that we had previously noted in the different forms cannot be regarded as of any value for distinguishing the species, and must merely be due to individual variation.

Zool. xii. p. 12) has been referred to this species by some authors; but that name is clearly based on Shaw’s Lerwea (‘Travels in Barbary,’ p. 243), which, as Gray has rightly pointed out, is referable to the Barbary Sheep (_Ovis tragelaphus_). [11] In his paper on the generic subdivision of the Bovidæ, P. Z. S. 1851, p. 170. [12] Dr. Günther, using the name given by Gray, speaks of this skull as that of _C. redunca_, but it certainly belongs to _C. fulvorufula_. [13] In Sclater’s List of Speke’s Mammals (P. Z. S. 1864, p. 103) this skull was referred to “_Kobus_, sp. inc.” [14] This reference was put down on a previous occasion (Vol. II. p. 23) to _Ourebia nigricaudata_, but on finding that Schinz’s name depended on it, a more careful study of the figure and description has been made, and we now consider that Sundevall’s reference of it to the Nagor was probably correct.
