*I agree with Mr. Tryon iu his statement in the Am. Jour. Conch , Vol. 

 i, p. 95, and consider the genus Siiunea, Risso, as a synonym o^ Amphipe- 

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

 patida, Pennant, are undoubtedly young shells. 



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

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

 {5owb., as its synonym.
