Var. fasiformis, Nevill, tom. cit.
" Well distinguished by its produced and fusiform shape ; the
whorls increase regularly and are more convex than those of
the type form, iu which the upper whorls are abruptly and coutractedly
attenuate, the lower ones increasing rapidly in size,
especially the last, which is always very tumid. In var. fusiformis,
on the contrary, it is only a trifle more swollen than the
preceding one. More solid and of brighter coloration ; sculpture
rather less distinct." (Nevill.)
Alt. 32-5 (9 whorls), diam. 9 mm.
