Obliquipithonella irregularis

"irregularis" Akselman and Keupp, 1990, p.172-173,175-178, pl.1, figs.1-19; text-fig.2.  Holotype: Akselman and Keupp, 1990, pl.1, fig.3.  NOW Pirumella.  Originally Obliquipithonella, subsequently (and now) Pirumella.  Motile equivalent: Scrippsiella patagonica Akselman and Keupp, 1990, according to Akselman and Keupp (1990, p.169).  Contrary to the opinion of Lentin and Williams (1993, p.452), the name Obliquipithonella irregularis can be considered legitimate, since Akselman and Keupp (1990) did not explicitly include the type of Scrippsiella patagonica in synonymy (I.C.B.N. Article 52.2d). Age: extant.
