According t<> Tryon the radula of this species is still unknown, and I am not aware that 

 it lias since been described. lts location amongst the Amphiperasidae has even been doubtfnl. 

 In an old radula of tliis species trom Amboina I see that by the characteristic mmblike uncini 

 the ^enus belongs without doubt to that family. The teeth of the central field are however 

 sufficiently different from its allies to consider the genus Calpurnus as a valid one. The rhachidian 

 tooth R has a broad body, with two wings near the base and a very large central cusp, 

 with one or two small denticles at its base. The laterals (1) have a subquadrangular body and 

 a very long archlike cusp, with a small denticle about halfway; these teeth are quite different 

 from those of other species of this family figured by Troschel.
