Clarke Co., Ala." 



This, as the figure shows is of a slender form, with surface 

 nearly or quite smooth except at the smaller extremity, where 

 five sometimes equal, but generally alternating longitudinal lines 

 are found extending from Y^ to Yj, of an inch from the apex. 

 This posterior or lesser termination is usually not entire; but 

 when intadl it shows a comparatively shallow slit on the ventral 

 or ex-curved side as indicated by pi. i, fig. i, a. 



When broken posteriorly an internal accessory tube is often 

 seen projedling beyond the exterior shell.

Dall says {op. cit.')-. "Z?. thalloide Q,ovx2A {D . alternatum Lea') 

 is very common in the Claibornian at Claiborne, near Clarksville 

 and Woods bluff, Alabama, Wautubbee and Newton, Miss., 

 and Creole Bluff, Louisiana." 



Leaving aside the question as to whether "very common" 

 applies to the Woods bluff locality or not, it seems to us doubtful 

 whether this species has been found at this locality at all. Our 

 enormous quantities of material from that outcrop fail to yield a 

 single .specimen; nor have Aldrich' s researches brought any to 

 light. The Eocene from Alabama colleAed by L. C. Johnson 

 and now in the U. S. Nat. Museum was often improperly localiz- 

 ed and this may account for the citation of the species at this 

 locality.
