Specific characterization. — General form more or less ellipti- 

 cal as indicated by the figures ; surface marked by fine, rather 

 sharply raised concentric lines ; umbonal ridge marked by a low- 

 fold extending from the beak to the posterio-basal margin, caus- 

 ing an emargination in the outline ; beaks not prominent ; den- 

 tition rather weak, but of normal elements. 



For description and illustrations of T. trumani see these 

 Bulletins, vol. 2, p. 265, pis. 18 and 20. 



This is of the same stock as tallicheti, and the left valve (fig. 

 5) from Lisbon, Ala., is in a way intermediate between these 

 two species, though more of the form of tallicheti. Notice that 

 on that specimen the place (in the left valve) showing a radi- 

 ating shallow furrow corresponds to the ridge already mentioned 

 in the right valve of the species here under discussion. 



We have onlj^ the type, the right valve, from the red clay 

 beds of the Orangeburg District, S. C. Now in the Paleontolog- 

 ical Museum at Cornell Univ.

Conrad's original description. — Shell elliptical, equilateral, much 

 compressed ; extremely thin and fragile, with regular concentric impressed 

 striae, most distinct on the anterior side ; posterior extremity angulated ; 

 lunule linear, impressed ; beaks not prominent ; apex acute ; cardinal 

 teeth prominent ; lateral teeth none. 



The twisting of the posterior, causing the left valve to be 

 deeper than the right might well have been mentioned by Con- 

 rad .
