The only description this form has had is by Dall. He says: 

 "The upper surface without spiral striation, the middle of the 

 whorl impressed, the suture simple-edged except in the very 

 young, the periphery wider and less decumbent; the umbilicus 

 smaller with 'the carina very finely transversely wrinkled, the 

 base smooth or with a few obsolete spiral lines. " It is here com- 

 pared to 5*. scrobiculatuni. 



Having examined the type of .S. texanum in the Academy's 

 colle(5lion, it appears that .S". texamim is synonymous with scrobi- 

 culatuni, hence the necessity of the new name proposed in the 

 Academy's Proceedings. 



Localities. — Ala.: Woods bluff; near Chodtaw corner. 



The type of this new species may be considered to be the 

 specimen herewith figured, from Woods bluff, in the Paleonto- 

 logical Museum of Cornell University.
