New South Wales; Tasmania. 
Var. LALLEMANTIANA, Crosse. PI. 17, fig. 86. 
Two of the revolving lines more prominent, ridge-like. 
C. incrusta, Tenison-Woods (PI. 34, fig. 99), is a smaller shell, 
7 mill., with two of the revolving strize more prominent (on the 
body-whorl 8-9), slightly keel-like. I figure it from a specimen 
sent to me by Mr. C. E. Beddome, of Tasmania. I believe it to 
be a synonym of C. Letourneuxiana, var., one of my specimens 
of the latter exhibiting a transition from the normal type with 
equal revolving sculpture to the form with two more prominent 
lines.
