„This remarkable species differs from the most others in possessing a distinct 

 tubulär wing at the mouth, which somewhat recalls the same feature in P t. albersi, 

 only the tube is more free and open. The only other species possessing a second 

 tube is Sp. mastersi figured in the Conch. Indica, pl. V Fig. 1, but not descri- 

 bed. In that species, howewer, the last whorl towards the mouth is free and the 

 peristomal tube less complete though longer than in the present form. " — Theobaid.
