This species in its varietal forms seems to be fairly well dis- 

 tributed in the Eocene series. In the more typical forms the two 

 .series of hinge teeth are each somewhat curved and lines drawn 

 tangentially to the mid portions of each would intersect at an an- 

 gle of 90°, whereas a similar construction about the hinge teeth of 

 7nagnifica would produce a much greater angle (compare figs, i 

 and 14). The projecting margins of the valves within the long 

 lunule make a fine distinguishing feature exteriorly. Lea's fig- 

 ure, indicating conspicuous radial striae is slightly misleading.

 Hickory and Wautubbee, Miss. Flatter, less abbreviated po.ster- 

 iorl}' and more difficult to distinguish from niagnifica, 3 and 6

For original description, see reference above. The type spec- 

 imen from the uppermo.st Sabine beds of Alabama seems to be 

 somewhat imperfect about the umbonal region . The specimen 

 herewith figured is from 5 miles N. of Orangeburg, S. C. in asso- 

 ciation w\Xh Lutraria lapidosa. It, too, is an internal impression, 

 but the hinge characteristics are well shown, both the ridge be- 

 low the muscular scar and the njaiiph supporting the ligament.
