The two cheek-teeth preserved seem to be the last premolar and first 

 molar. The former is a small laterally compressed tooth with a high 

 anterior cusp and a smaller posterior one which seems to belong - to the 

 eingulum ; there is also a slight cingular prominence on the front of 

 the tooth. The other tooth (first molar) is large and has the appear- 

 ance of a carnassial ; it consists of two main lobes, the anterior of 

 which supports three high cusps, of which one (paraconid) forms 

 the anterior angle of the tooth, while the others (protoeonid and meta- 

 conid) .are arranged transversely. The protoeonid is somewhat higher 

 than the paraconid, while the metaeonid, the top of which is broken 

 away, is the most massive of the three. Immediately behind the proto- 

 eonid, in the valley between it and the talon, there is a minute cusp. 

 The talon consists of two blunt cusps, much lower than those of the 

 anterior lobe ; the inner of the two, which is broken, was much the 

 larger. Behind these again there seems to have been a small promi- 

 nence belonging to the cingulum.

A bone of very remarkable form bearing a large tusk and the remains 

 of two smaller teeth may possibly be part of the upper jaw o£ this 

 species, but its characters are so peculiar that at present it can only be 

 briefly described and its full determination must be deferred till further 

 information is available. A sketch of this specimen is given in fig. 3. 

 Anteriorly the bone bears the socket for an enormous tusk-like tooth 

 which is triangular in section; the outer and inner faces are slightly 

 convex and meet in an acute anterior angle; the posterior face is nearly 

 flat. The outer and inner faces were enamel-covered, the posterior 

 apparently not. This tooth grew from a persistent pulp and its 

 posterior end is seen in section on the broken hinder surface of the 

 specimen; its total length measured along the outside of its curve 

 must have been upwards of 15 centimetres, of which about 5 centimetres 

 protruded from the socket. Immediately behind this tooth the alveolar 

 border bears a cavity which may represent an alveolus; behind this 

 again the border narrows to a thin edge bearing sockets for two small
