Cylichna erecta, sp. nov.
(Fig. 46).
A single rather worn example from the lagoon beach.
This species appears to be quite distinct from others of the genus. Those that share the cylindrical shape being C. discus, Watson, more truncated anteriorly; C. protracta, Gould, three times larger; C. involuta, Adams, C. cylindracea, Pennant, and C. alba, Brown, which appear to have the spire covered. No comparison can be instituted with a mass of unfigured species with which authors (Adams being chief sinner) have oppressed descriptive conchology.
