There is great variability in the length of the rostrum, and in some specimens 

 it may be much longer than is shown in the figures given by Hinds and Hanlev. 



Reeve's figure is very misleading, for the sculpture — which in reality consists 

 of an exceedingly pretty, fine, regularly concentric striation — in his figure is 

 highly irregular and undulating.
