CRANIA OP RUMINANTS PROM THE INDIAN TERTIARIES. 67—154 
Fmiily, — ANTIL OFIFJE. 
Genus: ANTILOPE. 
As stated in the introduction to the present memou% Dr. Palconer determined 
several species of antelopes from the Siwaliks, hut only one of these, mz.. Antilope 
palceindica, is known by anything more than its manuscript name. Of Antilope 
palceindica there are figures of the cranium given in the “ Palaeontological Memoirs” 
{Vol. I, Plate XXIII), and in the “Journal of the Asiatic Society of Bengal” 
{Vol. IV, Plate XLVIII, figs. 40, 41, and Vol. XII, p. 769, and Jigs. 1, 2, of accom- 
panying plate) ', the latter figure is accompanied by a short description from' the 
pen of the late Colonel Baker. The characteristic points of the cranium of this 
species are the great elongation of the face, the concavity of the profile, the 
absence or small development of the infra-orbital sinus, and the small size of the 
supra-orbital foramina. The horn-cores are approximated at their bases and directed 
upwards, backwards, and outwards in a simple curve, without any twisting; they 
are slightly compressed laterally ; the species seems to be allied to the African 
Hartebeast. 
In addition to the above species, I am now able to describe three new species 
from the Siwaliks, founded upon specimens of the horn-cores or crania which are 
in the collection of the Indian Museum ; the figured specimens were all obtained 
by Mr. Theobald. 
Several of the crania of the Siwalik antelopes differ considerably from the 
type forms of the genus, and should probably be placed in distinct genera or sub- 
genera ; I have thought it best, however, for the present to retain them under the 
type genera. 
Antilope Sivalensis, n. sp. PI. 25, fs. 1 & 2. 
This species is founded on a cranium obtained from the Siwaliks of the Kangra 
district ; it corresponds with the two less complete specimens in the collection of 
the Asiatic Society of Bengal catalogued by Dr. Palconer (Nos. S. 569, 573). 
This cranium is in a somewhat cracked and shattered condition, as is so com- 
monly the case with Siwalik fossils ; the two horn-cores are broken off shortly 
above their origin from the frontals ; the greater part of the nasals is also broken 
away, and the borders of both orbits are crushed ; on either side the whole extent 
of the zygomatic arch has been destroyed. The occipital condyles, together with 
the greater part of the boundary of the foramen magnum, are likewise absent ; 
the premaxillge and the extremities of the maxillae are abruptly broken off ; they 
have been restored in outline in the profile view. The crowns of the ultimate molar 
teeth are broken off close to their alveoli.
