Synonymy: 1791, Testaceorum Arenulae Marinae Tabulae Sex (Sechs Kapjertajeln mit Conchylien des Seesandes) University Press, Jena, pp. 3, 5, pl. 4, fig. 13a-e;

Description: Allowing for rather variable populations they resemble V. granulosa in almost every respect except that they rarely develop more than 2 to 3 uniserial chambers and they tend to swell to a maximum diameter in the middle part of the upper one third of the biserial stage.
Distribution: Waitakian to Tongaporutuan common, rare in Wanganui Series (Opoitian-Waipipian).
Comment: This specific name has been widely used for Miocene to Recent forms that fairly closely resemble the Recent species, V. pennatula. Finlay separated Waitakian and younger forms from V. granulosa in the Oligocene. Continued specific separation from V. granulosa is adopted because V. pennatula seems to be a distinct stage in the post Oligocene trend towards reduction of uniserial chambers.
