 Hab. — Dredged alive off Brighton and off Beaumaris, Port

Obs.- — -This species, though not very common living on our 

 shores at the present time, was very abundant during Tertiary 

 time, being a very common fossil species in the Victorian 

 Miocene (or Kalimnan) beds, and also extending into the 

 Eocene (or Balcombian) beds, but not in such great abundance. 

 The antiquity of this species is of interest, and its persistency 

 of form is remarkable, Avhile its distribution as a fossil mainly 

 accounts for its synonymy.
