this latter, in all but veiy old specimens, is very distinctly visible
within the aperture ; whorls seven, the first two or three generally
decollated, transversely superficially ridged, ridges more or less
obsolete towards the centre of the upper whorls, one of them
below the suture more prominent than the rest; columella pure
white; the operculum constantly differs on its inner side from
those of the other Burmese species by the remarkably raised ixnd
very rugose nucleolar portion and by the distinct, though minute,
granular margin.

Paludomus rcgulata, Benson, var., H. & T., 0. I. pi. 108, fig. 6.
Original description:—Differs from the preceding [P. anderssoniana]\)y
the slightly more rugose sculpture, by its more decollated

spire (more apparent in young specimens), by the columella being
apparently invariably faintly stained with brown, by the almost
entire apparent absence of colouration on the last whorl, especially
in the absence of the second broad band within the' aperture.
