Central facial band rufous, an indefinite nose-spot sometimes present; light facial streak fairly distinct, encircling the eye ; dark facial streak scarcely distinguishable against the fawn-colour of the cheeks; dark lateral band very strongly marked, almost black; light lateral band very indistinct; back and flanks of a deep foxy rufous ; pygal band almost or entirely obsolete.

As may be seen from the above descriptions, the points of difference between the Gazella rufifrons of Gray and the Gazella leevipes oi Sundevall are of the most trivial and insignificant nature. I have, however, considering the widely separated localities from which the type specimens of the two descriptions were obtained, thought it better for the present to leave the two names separate in this list. The Gazella leevipes appears to be the larger and more brightly coloured animal of the two. In some specimens I have found the knee-brushes wanting, as described by Professor Sundevall. This, however, is by no means an invariable character.
