piriformis (Keupp, 1977, p.66–67, pl.23, figs.1–5; text-fig.7) Lentin and Williams, 1993, p.520. Holotype: information not available. Originally Pithonella, subsequently Obliquipithonella, thirdly (and now) Pirumella. This combination was not validly published in Bolli (1980, p.528), since that author did not fully reference the basionym. Age: Tithonian.
Parent: Pirumella
