The above synonymy is partly taken from that compiled by 

 BRAZIER, who has published an excellent paper on Tasmanian 

 Trochidce in Proc. Roy. Soc. Tasmania, for 1886. 



Rather variable in sculpture ; the spaces between the spiral ribs 

 often occupied by lirula?. 



I am wholly unable to see any differential characters in Mr.

C. BLANDIANUS Crosse. PI. 40, fig. 22. 



Shell imperforate, elevated-conical, solid, rather thick, ornamented 

 with numerous oblique longitudinally impressed stride and spiral
