Catalog entries: Acrobotrys tritubus
type material: A. tritubusOriginal description: Cephalis trilobate, with large subglobular [antecephalic] lobe, smaller globular [cephalic] lobe, and inflated-conical [postcephalic] lobe, lying in the same plane. [Antecephalic] lobe bears two slender cylindrical tubes, one directed apically and the other posteriorly. [Postcephalic] lobe bears a slender cylindrical tube directed anteriorly. Thorax subcylindrical, inflated, or ovate, often with somewhat constricted mouth. Shell surface smooth, perforated by numerous small circular or subcircular pores, irregularly arranged.
