Revised descriptions of New Zealand Cenozoic Mollusca from Beu and Maxwell (1990)
(Pl. 26s): lectotype, Pakaurangi Point, Kaipara Harbour, Otaian? (TM5419, GNS) (probably from the "pteropod bed" in Waiteroa Member, Holland's Bay, Otaian).
(Pl. 26t): lectotype, Pakaurangi Point, Kaipara Harbour, Otaian? (TM5419, GNS) (probably from the "pteropod bed" in Waiteroa Member, Holland's Bay, Otaian).
Beu & Maxwell (1990): Chapter 11; p. 238; pl. 26 s,t.
Synonymy: Vaginella torpedo Marshall 1918, p. 263, pl. 22, fig. 7, 8; Beu & Maxwell 1990, p. 238, pl. 26s, t; Cuvierina (Cuvierina) torpedo, Janssen 2005, p. 29; Janssen 2006, p. 73, fig. 1-4.
Description: Moderately large for genus (height 11.5-13.5 mm), sheath-shaped, apex broken off most specimens, tube sealed by convex septum. Early part of shell conical, later part subcylindrical, with ventral side somewhat more convex than dorsal side except near aperture where ventral side is slightly concave. Shell slightly wider near middle and at aperture than in between. Sculpture of weak transverse growth lines and exceedingly fine longitudinal striae, otherwise polished. Aperture reniform, lip thin, rounded, not expanded, slightly higher dorsally than ventrally.
Comparison: Although tradiionally referred to the genus Vaginella, V. torpedo was transferred formally to Cuvierina (Cuvierina) by Janssen (2006, p. 73) in his review of the classification of several "pteropods" recorded from New Zealand. He also transferred Vaginella aucklandica Clarke, 1905 (Otaian, Auckland) to Ireneia Janssen, 1995, Clio (Creseis) urenuiensis Suter, 1917 (allegedly from Whitecliffs, Taranaki (Tongaporutuan) but almost certainly from the Waitemata Group near Auckland (Otaian or Altonian); F.R. Brook, pers. comm.) to the synonymy of Ireneia calandrellii (Michelotti, 1847), although some spoecimens referred here are actually I. nieulandei Janssen, 1995, and Vaginella inflata Hayward, 1981 was transferred to the synonymy of V. depressa Daudin, 1880, the type species of Vaginella (family Cavoliniidae). A.W. Janssen has also recorded several other taxa of "pteropods" from New Zealand that have type localities in Europe, reflecting the cosmopolitan distributions of these holoplanktonic species.
Distribution: Late Otaian-early Altonian, Pakaurangi Point, Kaipara Harbour (type).
