broad, though scarcely broader than the shell ; its frontal 

 angles are rounded. Posteriorly it exceeds the length of 

 the shell by a third of the length of the animal ; it is flat- 

 tened above caudally, and shows a whitish central line and 

 radiating lateral streaks : the extremity is obtuse. This 

 creature is active and not shy ; when at rest it puckers its 

 mantle. 



It is essentially a southern and western species. We 

 have dredged It alive In the crevices of AlcT/onmm off the 

 Land's End in twenty fathoms water (E. F. and R. 

 M'Andrew) ; Exmouth (Clark) ; Plymouth (Barlee) ; 

 Birterbuy Bay, and Arran in Ireland (Barlee) ; " Ma- 

 gilligan in Londonderry [Mrs. R. A. Hyndman] " 

 (Thompson). 



It ranges to the Mediterranean.
