Yar. SICULA, Cantr. PI. 6, figs. 95, 96. 



The older authors g#ve 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 differing only in size, 

 was found in the Mediterranean and identified by Philippi 

 (Enum. 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. sicula. At the best Cantraine's species is but a variety, of 

 which T. fallaciosa, Tiberi, is a synonym.
