Yar. sicuLA, Cantr. PL 6, figs. 95, 96. 



The older authors gave the East Coast of Africa as the habitat 

 of S. stramineum^ but afterwards a smaller shell agreeing with 

 this species in sculpture and color, and difi'ering only in size, 

 was found in the Mediterranean and identified b}^ Philippi 

 (Enura. Moll. Sicil.,i, p. 173) as the same shell. Cantraine con- 

 sidering the difference in size and the widely separated habitats 

 has made the Mediterranean shell a distinct species, and named 

 it T. Hicula. At the best Cantraine's species is but a variet^y, of 

 which T./aZZaciosa, Tiberi, is a sjnionym.
