ANNOTATED LIST OF THE SHELLS OF ST. AUGUSTINE. FLA. 



RY C. \V. JOHNSON. 



Crepidnla r/laiica Say. I think there is no doubt but that C. 

 glauca and C. convexa are the same species — their form depending 

 on the object upon which they have grown. But I doubt whether 

 thev are varieties of C. fornicata. In the series before me the follow- 

 ing characters seem to distinguish them from the typical young of 

 C. fornicata. Apex distant from the margin, septum thinner and less 

 depressed. 



Crepidida unguiformis Lam. Common. 



Crepidnla aculeata Gmel. Not common. 



Scala angidata Say. Common. 



Scula humphreyii Kiener. Common. 



Scala midtistriata Sax. One specimen. 



Scala turricida So^Yb. Not common. 



Seala lineata Say. Not common. 



lanthina fragilis Lam. A few after a storm. 



Vermetus spiratus Phil. var. radicula Stimp. A few on the ocean 

 beach. 



Turbouilla areolata Ver. One specimen. 



Odostomia impressa Say. Common on oysters. 



Columbella lunata Say. Common upon sea weed. 



Columbella avara Say. Common. 



Cancellaria reticulata. A few sea-worn specimens. 



Terebra di.slocata Say. Common on the sand bars in the harbor. 



Clathurella 2)licata C. B. Ad. Common among oysters. 



Daphnella cerina Kurtz & Stimp. Common among the wash of 

 small shells on the ocean beach. 



Strombus pugilus Linn. A few sea-worn specimens. I have 

 never seen a trace of Strombus costatus Gmel., in this locality. 

 Bahama specimens are common in the shell stores. I have specimens 

 from Lake Worth, Fla. (250 miles south). 



Trivia pedicidus Linn. Several sea-worn specimens. 



Ovula unipUcatnm Sowb. Common on the Leptogorgia virgulata, 

 a species of Gorgonia. As this varies in color (orange, yellow, white 

 and purple), the shells to a great extent partake of the color of the 

 Gorgonia on which they live. 



Ovula gibbosa Linn, One living specimen on the Leptorgia.
