recent species, and when complete may very probably 

 have had the same general direction. The molars are of 

 a narrow elongated type (as in the recent species) and have 

 no distinct internal accessory column. The structure of 

 these teeth, the high-pitched ridge between the horn-cores, 

 the close approximation of the latter, and the absence of 

 any lachrymal fissure, at once distinguishes this specimen 

 from the cranium of Hippotragus sivalensis. Its close 

 resemblance to that of Alcelaphus pygargus indicates very 

 strongly its generic identity. 



It may be observed that the present specimen presents 

 some resemblance to the cranium of Palceoryx pallasi 1 ; 

 but the horn-cores of the latter are placed more posteriorly, 

 and there is no lachrymal depression.

ANTELOPES OF UNCERTAIN GENERIC POSITION. 



Species 1. (Probably allied to Oreas.) 

 Hob. India. 



16657. Fragment of the right maxilla of a very large Antelope, 

 probably allied to the Eland, showing the last five cheek- 

 teeth ; from the Pliocene of the Siwalik Hills, India. This 

 specimen is noticed by the present writer in the ' Palason- 

 tologia Indica,' ser. 10, vol. iii. p. 114, note 4.

Species 2. (Of uncertain affinity.) 

 Hab. India. 



39559 b. The hinder portion of the cranium, with the base of the 

 right horn ; from the Pliocene of the Siwalik Hills, India. 

 This specimen is noticed by the present writer in the 

 Geol. Mag. dec. 3, vol. ii. p. 171 (1885); and is distin- 

 guished from the two preceding species by the nearly 

 vertical direction of the base of the horn-core, the absence 

 of distinct supraorbital pits, and the much more obtuse 

 angle formed by the junction of the facial and frontal 

 planes. It strikingly resembles an imperfect cranium 

 from the Lower Pliocene of Pikermi, figured by Gaudry in 

 the ' Animaux fossiles et Geologic de 1'Attique,' pi. Hi.
