being less distinctly defined than on the neck and more or 

 less losins: tiiemselves in tlie brownish colour of the inter- 

 vening spaces. Tlie lower half of the quarters and of the 

 shoulder, as well as the belly, are whitish, the pale tint of 

 the latter region being rather sharply defined from the dusky 

 tint of the flanks. The belly-stripe is distinct, but the legs 

 are without stripes, though the knees and shins of the fore 

 legs and the pasterns and fetlocks of fore and hind legs are 

 distinctly brownish. There are no shadow-stripes in any 

 way comparable in extent and distinctness to those which 

 were visible in the specimen described by Gray, there being 

 none visible upon the neck and those on the flanks and 

 quarters being merely represented by indistinct patches or 

 blotches. And, lastly, it may be mentioned that the spinal 

 stripe is separated from the upper ends of the flank-stripes, 

 but is touched on each side on the rump by a short branch 

 from the adjacent stripe. The nostril-patches are black. 



The example in the Tring Museum, so far as could be 

 judged from a cursory examination, differs from the one just 

 described in two respects — namely, the upward extension of 

 the flank-stripes to touch the spinal stripe and the presence of 

 bars upon the knees and hocks. 



On account of the prevalent misconception as to the 

 characters of the true Burchell's zebra, a sketch taken from 

 the specimen in the Bristol Museum has been published on 

 p. 41 of this paper. 



There is no specimen of this zebra in the British Museum, 

 and it appears to be scarce in the menageries and museums 

 of this country ; and on account of the general application of 

 the term Burchelli to any or all of its subspecies, we are in 

 ignorance of the exact area that it now occupies in S. Africa.

According to the figures published by Hamilton Smith and 

 Matschie, and to the description given by the latter author, 

 the zebra that received the name antiquorum^ on the suppo- 

 sition that it was specifically identical with the one seen in 

 the early days of African travel in the Congo region by 

 Pigafetta, differs from Burchell's zebra in having the stripes 

 extending over the quarters almost down to the hock and 

 from the shoulder to the knee, while those on the flanks, 

 instead of stopping short where the white of the belly begins,
