Harris' original description. — "Size and general form as figured; 

 volutions 6, spiral whorls shouldered and somewhat costate; su- 

 ture obscured by foliae developed by the intermittent mode of 

 growth of the sutural callosity; body whorl below scarcely dis- 

 tinguishable from the non-umbilicate varieties of P. vetusia, while 

 above, the shoulder and the sutural folise at once definitely char- 

 acterize the species.

Conrad's original description. — "Subglobose, with revolving 

 striae, obscure, except the base, where they are distinct, spire 

 short, rapidly narrowing to the apex, which is acute; tooth short 

 and robust, placed at the termination of an exterior groove; 

 basal margin profound; labrum acute on the margin." 



The specimen so described was from Claiborne, Ala. It is 

 known in nearly ever}^ horizon in our Eocene series. 



The Midway specimens we obtained are all fragmentary, but 

 several show clearly the characters of the species.
