Common, though the species occurs nowhere in such ahundance as 

 astarte borealis. 



The majority of the specimens can be referred to the variety 

 warhami, HANCOCK. However the variety striata LEACH is by no 

 means scarce, though globosa MOLLER on the other hand is very rarely 

 met with. 1 append some measurements showing the variations which

 The maximal size of the species is 27.4 mm. (KNIPOWITSCH).
