separated from the canines by a space. In S. onwtus the bony 

 palate is much broader behind the last molars, and does not extend 

 so far backwards (Plate XV. flg. 6 a). 



In the upper jaw the teeth (with the exception of the incisors, 

 which are separated from the canines, and have an acute short pos- 

 terior cusp) are very similar in both species ; in the lower jaw the 

 first premolar is less crushed in between the canine and second 

 premolar than in any other species of the genus ; it is, however, 

 similarly flattened from before backwards, and has two short cusps 

 arising internally from the cingulum which are not found in the 

 other species (fig. 6 b).
