﻿PLAN AXIS.

apical polished, otiiers spirally grooved above 

 and below ; last large, very strongly grooved be- 

 low ; aperture large, patulons ; outer lip very 

 thin, very finely ridged within, sutural notch 

 rather rounded.

Mr. Smith mentions as a variety a specimen in 

 which the posterior callus and inflected edge of the 

 enter lip almost meet, so as to form a rounded hole 

 like that in Pupina. I regard this as only a slight 

 malformation. Yet the slit in this species is gene- 

 rally rounder than in rhniaxis siinilis.

The species is subject to some variation, one variety 

 being nearly white and another (in the British 

 Museum) with only a broad cjerulean band in the 

 middle of the whorls.
