This species is somewhat more slender and graceful than C. ste- 

 Mdi var. dipUj. of Kyushu, with more ^^^f f ;;; ^;: j);;:^;^ 

 but it differs chieflv in the much closer approach of the mfeuor to 

 tiL superior lamell. in the aperture, the continuity oi i^^^Ver^ 

 ^vith the spiral lamella, and the deeper penetration of both spiral 

 and inferior lamell.. As in C. sieMdi, ^J- PO-^ion of ^he 

 wanting lunella is indicated by a pale area in the shelh The 

 clausilium differs, being broadly rounded at the apex in a ne^- 

 opsis, and without excision near the filament, while in C M 

 var. dipty. the apex is angular and there is an abrupt exci.ion on 

 the palatal side of the filament. X7.„,v, or
