30 PLEISTOCENE MAMMALIA. 



Caprovis Vignei, or the Argali of Ladak (Coll. Surg. 3778). It is, however, also paralleled 

 by that in a skull of an old male Ovibos in the College of Surgeons (3814). The direction 

 of its horncores is downwards and forwards. In all other respects both these skulls so 

 closely resemble Ovibos moschatus, that were it not for the points noted above, I should 

 believe that they belonged to that animal. Beyond all doubt they represent a closely allied 

 species of the same genus Ovibos. 



§ 2. General Conclusions. — In this Essay I have brought forward the evidence in 

 favour of the following conclusions : first, that Ovibos was rightly classified by De Blainville 

 with the Ovidce, and not with the Bovidcs ; secondly, that it has no classificatory relation- 

 ship with Bubalus Gaffer, as Professor Owen maintains, both in his original article and in 

 the ' Anatomy of the Vertebrates.' And lastly, that it has a greater range in time than 

 was suspected, having been a contemporary with the Megarhine Rhinoceros during the 

 early portion of the Pleistocene period, when the Lower Brick-earths were being deposited 

 in the valley of the Thames.
