*I atrree with Mr. Tryoii in his statement in the Am. Jour. Conch , Vol. 

 i, p. 95, and consider the genus Simnea, Risso, as a synonym o? Amph/'pe- 

 ras, Gron. The two species referred to it, viz., S. aperta, Sowb., and S. 

 patida, Pennant, are undoubtedly young shells. 



The former closely resembles V. hirostris, jun., Linn., and has been 

 placed in its synonymy., and the latter, A. patula, with A. Adriatica, 

 Sowb., as its synonym.
