A few years ago I described some remains of Antelopes from the Pliocene Siwaliks of India, when I employed the generic term Antilope in the wide sense in which it was used by the older zoologists and palæontologists. At a later date I was enabled to refer two of the species thus designated to two of the genera of Antelopes as at present classed; and at the same time mentioned some other forms. A recent examination of all the remains of this group from the same deposits contained in the British Museum has enabled me to make a more exact determination in the case of another of the species mentioned in my first notice, and also to indicate the existence of other forms closely allied to existing African Antelopes. These new forms I hope to have an opportunity of describing on a future occasion, and, therefore, now content myself with merely giving a list of the species which I can at present recognize. The ill-defined character of some of the genera of existing Antelopes renders it in many instances a matter of extreme difficulty to be quite sure as to the affinities of their fossil relations.
