All representatives of this species were found in a ravine north of 

 Clermont, Iowa, and none in the neighboring outcrops. They con- 

 form well to the types figured and described by Foerste, although the 

 average size is somewhat smaller. They all lack the vertical wrinkling 

 along the hinge-line of Strophomena vetusta. The cardinal angles in 

 all cases are acute, and no specimen shows the rectangular boxing of 

 the postero-lateral angles.

 Average specimen — width, 44 mm., length, 27 mm. 



Locality: — The Richmond at Oxford, Clarksville, WaynesviUe,
