Conus peali Green? Shells collected at Long Key seem to agree 

 ' tolerably well with description and figures of the above, but are larger 

 than the dimensions given for that species. 



Conus proteus Hwass. West coast. Often washed on shore, but 

 generally worn. Probably a deep-water species. 



Conus nuts Hwass. A number of very fine living shells were col- 

 lected on the Tortugas reefs at low water. 



Conus pygmceus Reeve. West coast. Nearly jet black shells, with 

 white squarish spots, were found in Magill's Bay. Further south, the 

 shell is ofcen whitish, with yellow or brown spots, and grooved through- 

 out the entire body-whorl. I have the same shell collected on the east 

 coast of Honduras, which is very dark and covered with pustules. I 

 also have it from Panama. 



Con in cardinal is Hwass. A single slightly worn shell was found at 

 the Tortugas which seems to be this species. 



Conus magellanicus Hwass. Tortugas. Worn shells were found at the 

 above locality which appear to be this. The species is found at the 

 Bahamas. 



Natica pusilla Say. Young living specimens were dredged in Tampa 

 and Terraciea Bays. 



Natica duplicata Say. Abundant on west coast, being found from 

 the open sea up to nearly fresh water in rivers, and quite variable. 

 There is a flattened form found in the open sea which approaches N. 

 Josephines, in shape. 



Natica canrena L. West coast; more abundant southward. 



Natica uberiana D'Orb. Tortugas; Key West; Florida Keys. 



Natica mamillaris Lam. Tortugas; one worn shell. 



Natica marochiensis Gm., var. livida Pfr. Marco; one fine shell. 

 Occasionally found on the south-west coast. 



Sigaretus perspectivus Say. West coast, on sand flats at low tide. 



Sigaretus inaculatus Say. Long Key; one shell in fairly good con- 

 dition. 



Lamellaria pellucida Verrill. Long Key; one shell. 



Calyptnea candeana D'Orb. West coast; Long Key. One living 

 specimen and an abundance of dead shells were dredged in Tampa Bay. 



Cochliolepis parasiticus Stimpson. Passage Key; dredged in Tampa 

 Bay. A few shells, all dead. 



Crepidula fornicata Say. One of the most abundant shells in the 

 vicinity of Tampa Bay. 



Crepidula glauca Say. Mr. Tryon makes a species of this, but I have 

 no doubt that it is a variety of the very variable C. fornicata. 



Crepidula convexa Say. I have shells from Tampa Bay and vicinity 

 that agree perfectly with figures and description of this species, as well 

 as with shells from the New England coast. I have often found it
