TERTIARY FAUNA OF FLORIDA 



Section Asaphis s. s. 



Shell large, thin, gaping behind, with rather uniform radial sculpture ; two 

 prominent cardinal teeth in each valve, the larger bifid ; the pallial sinus 

 moderate, rounded in front, partly confluent with the pallial line below. 



A. undulata and multicostata are described by Gabb from the Cretaceous 

 of California, but neither has the aspect of genuine Asaphis. 



Section Hetcroglypta von Martens, 1880. Type Psammobia contraria 



Deshayes. Isle Bourbon. 



Shell with diverse sculpture converging in angles like that of Goniomya, 

 otherwise like Asaphis. The original use of the term by von Martens was 

 more inclusive, but I have preserved the name for the typical species.
