Peristichia is a genus of sea snails, marine gastropod mollusks in the family Pyramidellidae, the pyrams and their allies.[2]
Taxonomy
In his original paper, Dall proposed Peristichia as a genus of dubious affinities and placed it later in the family Pyramidellidae. Paul Bartsch, his collaborator, later thought it was a subgenus of Turbonilla.[3] Johannes Thiele does not even mention this genus in his Handbuch der Systematischen Weichtierkunde. (1929). Wilhelm August Wenz in his Handbuch der Paläozoologie, Band 6, Gastropoda, also thought it was probably a subgenus of Turbonilla, but added a question mark. However, a close examination shows that it belongs in the family Pyramidellidae, close to Tryptichus Mörch, 1875, differing from it only in having one (instead of two) basal entral spiral cords and having no columellar fold.
