A couple of additional notes on Campanile:

If I recall correctly, a talk at AMS reported that they are genetically
rather distinct from cerithioids, based on mitochondrial gene order.

There is some disagreement about the type of Campanile.  Le Renard
(Cossmanniana, 1(2-4):1-14) cites a monograph by Delpey.  Fischer 1884 did
not designate a type; both symbolicum (as laeve Quoy and Gaimard non Perry)
and giganteum were included.  Cossmann (1906) designated giganteum as the
type, but as the original genus description includes features of the
operculum, symbolicum seems to better fit the original description of the
genus.  If symbolicum is considered the type, then Campanilopa Iredale,
1917 is available for giganteum and its relatives (with sculpture very
different from the modern species).

Dirocerithium is not the only New World campanilid.  Jung has an impressive
foldout plate of a Caribbean specimen, closely related to giganteum but
bigger and a good candidate for largest known gastropod.  I do not have the
exact reference at hand.  Specimens of this group occur in various parts of
the Caribbean and Florida.
