No. 581. Antilope Palceindica. — Fine cranium of an antelope, com- 

 prising two horn-cores, both orbits and the facial portion as far as the 

 diasteme with the line of molars on either side ; the specimen is at once 

 distinguished by the close approximation of the horn-cores, by the 

 sudden inclination which the posterior jmrt of the frontal makes with the 

 nasal plane in a line with the middle of the orbits, and by the deep 

 lachrymal fossae in front of the orbits. The specimen agrees most 

 closely in form and proportion with that figured at vol. xii. Journ. As. Soc. 

 p. 770, figs. 1 and 2, described by Captain Baker. The horns diverge 

 slightly and at the same time curve backwards and outwards. The 

 species differs very remarkably in form from any Asiatic antelope 

 known, and Captain Baker compares it to the Sassaybe or Acronotus 

 lunatus. It is considerably larger than Antilope cervicapra — more 

 nearly approaching the size of the Nylghau. Occipital and sphenoidal 

 regions entirely wanting. Molar teeth devoid of any accessory pillar 

 between the barrels.

The supra-orbital fossse are very deep and marked, as in the 

 Antilope cervicapra and as shown in Captain Baker's figure, although 

 otherwise described in his paper. The supra-orbital foramina are very 

 much smaller than in that species. ( Vide Plate XXIII.) 



No. 582. Antilope Palceindica. — Another specimen very like the 

 last, but more perfect, contained in a mass of matrix enveloping a great 

 number of bones of different animals in all directions, among others 

 apparently the metatarsal extremity of a Sivatherium. The right horn- 

 core is of considerably greater length than in No. 581, and diverges 

 outwards exactly as in Captain Baker's drawing; orbits, zygomatic 

 arches and molars on both sides are present, but covered with matrix.

Figs. 40, 41, and 42 are different views of a skull of an animal allied 

 to the Antelope ; the length and narrowness of the face, the height of the 

 nose, and the peculiar setting on of the horns are all more conspicuously 

 exemplified in another specimen of a similar skuU, which Colonel
