There can be no question that v. Hasselt's group Geotrochus was founded on species of Trochomorpha or Trochonanina. "Under the generic name Geotrochus, I group three little shells, agreeing with Trochus in form of the shell, but with Helix in the animal." The species obtusus, turriculatus and zonatus are enumerated by v. Hasselt. The absence of true Papuina in Java, and the abundance of Trochonanina at the localities visited by Hasselt, cause Dr. v. Martens to surmise that he had before him Helix winteriana and conus or allied species. Swainson and many others have used the name Geotrochus for H. pileus and allies, and it is an unfortunate circumstance that the change is necessary.
