*I agree with Mr. Try on in bis statement in the Am. Jour. Conch , Vol. 

 i, p. 95, and consider the genus Simnea, Risso, as a synonym of Amphipe- 

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

 patula, 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. Adrmtica, 

 riowb., as its synonym.
