exception of the process descending on the outer side of the nasal, while the horn- 
core has lost about one-quarter of its 
length. In the laterally compressed 
horn-core, the form and position of 
the supraorbital foramen and sulcus, 
and the relative shortness of the 
frontal, 1 the specimen agrees so 
exactly with the gazelles, that its 
reference to the present genus may 
be considered certain. It indicates 
a considerably larger species than the 
Indian G. bennetti, and in this respect 
agrees with the east African G. granti , 
although differing slightly in the form 
of the supraorbital sulcus and the 
curvature of the horn-core. It agrees

Frontlet. — The frontlet represented in pi. IV. fig. 6 was obtained from Niki in 
the Punjab, 2 and has hitherto been included in the preceding species ; it agrees 
exactly in size with the frontlet of a male of G. bennetti , and if adult, as appears to 
be the case, is too small to be the female of G. porrecticornis. The specimen is too 
imperfect to afford a specific diagnosis, but it not improbably indicates the existence 
in the Siwaliks of the Punjab of a gazelle closely allied to the living Indian species.

Distribution . — The genus includes a considerable number of species inhabiting 
tropical Africa. An antelope has been described by M. P. Thomas 4 under the name 
of Antilope tournoueri from the upper pliocene of Algeria, which is regarded as allied 
to the present genus.

Museum (No. M. 2402) from the Siwalik Hills, which was provisionally referred to the 
present genus.
