Our specimen, although much larger than the measurements given 

 "by d'Orbigny, agrees so closely in all other characters, that there 

 can be little doubt of its being identical. The similar species (S. 

 turricula Sow.) has not the sutural spines characteristic of this 

 species. It bears some resemblance to S. vittata Jeffreys and S. 

 Algeriaiia Wienkauff, from the Mediterranean.
