Lucina radians, Tuomey $ Holmes, Ploiocene Foss. So. Ca., p. 57, pi. 18, fig. 4 and 5. 



Description. Shell orbicular, concentrically and regularly striate; radiately and 

 obsoletely striate ; lunule excavated. 



The beaks are prominent and acute, the concentric lines are close and well-defined, 

 the radiating lines somewhat irregular, and on the anal side more distant and promi- 

 nent. L. multilineata resembles the young of this species, but the radiating lines 

 are more regular and the shell more convex than in the species under consideration. 



This pretty species is found on the coast of North and South-Carolina, and in the Post- 

 Pleiocene. It is readily distinguished by its prominent umbones, close and regular 

 concentric striae and obsolete rather irregular radiating lines. — T. ^ H.
