The only specimen is still young, but perfectly agrees in sculpture with the upper whorls 

 of an adult specimen from the Philippines. Tryon considers it to be the same as T. lotorium 

 Lin., he says: "the distinctive characters are individual only". As far as I can judge, I think 

 the differences of sculpture are sufficiënt to separate them specifically. The young shell is covered 

 by a thin epidermis with long bristles on the radiating ribs and varices.
