MELVILL : MOLLUSCA OF S. CAROLINA AND FLORIDA. l6l 



Fam: NATICID^E. 



48. Natica campechiensis (Recluz.) 



I take the South Carolina mollusc, usually called 

 duplicata (Say), to belong to this species, but all the Neveritse 

 of Risso are similar, and probably most of them wide 

 spread varieties of one species. N. djiplicata (Say) is prob- 

 ably a variety of N. heros (Say), which I noted as very com- 

 mon in Nahant Harbour, Massachusetts, but I found nothing- 

 approaching it in South Carolina. 



49. N. sp. Not in good condition. Allied to the albula 

 section. Key West. 



50. Sigaretus perspectivus (Say). 



Sullivan's Island, South Carolina. 



Fatn: SCALARIDyE. 



51. Scalaria angulata (Say.) 



Sullivan's Island, Charleston Harbour. 



52. S. venosa (Sowb.) 



Key West. 



Fain: TEREBRID^. 



53. Terebra dislocata (Say.) 



Charleston Harbour. 



Fam : PYRAMIDELLID^. 



54. Obeliscus terebellum (Miill.) 



In fragmentary condition. Key West. 



55. Chemnitzia Indianola (Sowb.) 



Appalachicola, Florida, Gulf of Mexico. 

 Fam: CONID^. 



56. Conus leoninus (Hwass.) 



Key West. Perhaps a variety of spurius (Gm.) 



57. C. L'Argiliiertii (Kien.) =- Japonicus (Hwass.)
