ranges to tlie Mediterranean. It is undoubtedly the same as 

 Adriaticum^ Sowb. (Thes. 99, f. 13, 14, sp. 12,) which has a 

 thickened inflected denticulate outer lip. The patulum is not 

 mature. I find in a series from Torbay, presented by Sowerby 

 to the Academy of Natural Sciences, one specimen that is 

 thus thickened, and also in the Adriaticum, Sowb., (Ex. Auct.,) 

 one immature species which is exactly like i\\Q patulum. 



Patulum has priority as the specific name, and Adriaticum 

 must be placed in its synonymy. 



The third species, S. unipllcata, Sowb. (Thes., pi. 100, f SO- 

 BS, sp. 35,) has a very prominently thickened lip. It is excel- 

 lently well figured. Specimens from South Carolina and 

 Georgia, are in the Academy's collection. The genus Simnia 

 therefore, bereft of its species, will not stand, and must be 

 considered synonymous with Ampldperas, Gronov., [Ovida 

 Brug.,) into which its three species merge.
