TERTIARY FAUNA OF FLORIDA 



margins not excavated ; incremental lines strong ; radial sculpture of about 

 forty rather sharp, minutely nodulous, narrow threads, with usually wider but 

 often somewhat irregular interspaces, sometimes carrying a slender intercalary 

 thread or faint traces of radial striation ; submargins almost free from radial 

 sculpture, not impressed; hinge-margin short, pit large, wide, with a pro- 

 jecting lower margin ; basal margin of the valve rounded, hardly crenulated 

 by the sculpture. Alt. 37, lat 35, diam. 24 mm. 



This shell is much like the recent Z. inflata Gmelin, but is constantly 

 wider, less oblique, and differs in minor details. It appears to be one of the 

 characteristic species of the Caloosahatchie marls.

Pliocene of the Caloosahatchie, Monroe County, Florida, Heilprin, 

 Willcox, and Dall ; Pleistocene of South Carolina and the West Indies ; 

 recent from Cape Hatteras, North Carolina, to the island of Trinidad, West 

 Indies. 



This well-known species occurs in excellent condition in the Pliocene 



marls.

Pliocene of the Caloosahatchie, Monroe County, Florida ; Pleistocene of 

 the West Indies ; recent from Cedar Keys, Florida, south to Barbados, West 

 Indies. 



A single valve of this form, which is, perhaps, little more than a variety 

 of L. scabra, was obtained from the marls.
