„This remarkable species differs from the most others in possessing a distinct 
tubulär wing at the moutli, 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. mast er si figured in the Oonch. Indica, pl. Y Fig. 1, but not descri- 
bed. In that species, ho wewer, the last whorl towards the mouth is free and the 
peristomal tube less complete though longer than in the present form.“ — Theobald.
