Represented by several teeth, of which I select the largest and most 

 perfect as type. The lateral denticles are well developed, though not large. 

 The median cusp is rather narrow and moderately curved antero-posteriorly. 

 The posterior surface is smooth, the anterior coarsely striate at the base. The 

 fangs of the root diverge strongly, but, what constitutes a peculiarity of the 

 species, project far forward and outward at their point of junction below the 

 crown, reminding one of the pygal region of the Hottentot Venus.
