This species has been recorded l>y d'Orbignv and Reeve from the east coast of 

 Patagonia, and by M. Bavay from the shores of Argentina. M. Bavay also mentions 

 its occurrence iu a fossil state in several places on the coast of the Province of Buenos 

 Aires. Only young specimens were obtained at Station 42, and these 'exhibit the 

 variation in the number of costse and sculpture indicated by ^\I. Bavay.
