1977 Lagena tagusensis McCulloch : p. 48, pl. 50, fig. 10.

Remarks. The specimens differ from the type specimen by lacking the phialine lip on the apertural neck and from Lagena crenata ( Parker and Jones, 1865) by possessing a smooth apertural neck without ornamentation and much fewer ridges on the chamber.
