Conrad' s original descriptioi. — "Cylindrical, with strong long'i- 

 tudinal lines and minute revolving wrinkled striae; a slight devia- 

 tion crowns the whorls, defined by a separating line; spire very 

 short, apeK rather obtuse; suture distimft; inferior portion of 

 the columella with an elevated profoundly striated callus, above 

 which are three or four lines revolving to the base; aperture 

 gradually contra<5led above and effuse at the base. 



Locality. — Ala., Claiborne, Middle Tertiary. 



"Of the species described by Lamarck, this shell approaches 

 nearest A. canalifera. These two species do not correspond 

 entireh' with the genus Ancillaria, as the aperture is mu^h longer, 

 the shells are striated, and the suture is .somewhat channeled. 

 They might constitute a separate genus by the name of OLIVULA, 

 and would connect Ancillaria with Oliva.'''' 



The lyignitic form of this species differs considerabh' from the 

 typical Claibornian; it is smaller, heavier, smoother, and with 

 much higher spire. Specimens from the Lower Claiborne beds at 

 Smithville, Texas, have the high spire of the Lignitic specimens, 

 but in other respects approach closely, except in size, the typical 

 forms.
