back at an angle of perhaps 30° from a true radius; in approach- 

 ing the carina, however, they curve slightly forward, having 

 passed the same the}'- pass nearly verticall}^ downwards though 

 inclining slighly forwards; at the lower carina they are deflected 

 slightly backwards; spiral striation very faint in the specimen 

 figured, though doubtless fine, even, and everywhere present on 

 well preserved specimens. 



Locality. — This specimen (the only one known) belongs to the 

 collection of the U. S. Nat. Museum and is marked "264a, Wil- 

 cox Co., Ala., Iv. C. Johnson," collector. The nature of the 

 matrix in which this specimen was embedded renders it safe to 

 saj' that it came from bed 18, sect. p. 31, a mile or two south or 

 southwest of Palmer's mill.

Aldridf s orighial description. — "Shell broadly fusiform, whorls 

 eight, spire high; suture distinct, whorls concave and compressed 

 just below the suture; covered at this point with fine transverse 

 lines, remaining space smooth. Body whorl large, smooth below 

 the the above-mentioned sutural area, narrowed below into a 

 short, stout canal which is marked by fine revolving lines. 

 Aperture about two- thirds the length of the shell; outer lip 

 sharp, thickened and crenulate within; inner lip concave above, 

 straight below; callus not heavy. 



''Locality. — Matthews' Landing, Ala." 



Our specimens from this locality are f ragmen tar}^ hence I have 

 copied Aldrich's figure. An imperfect cast from bed b at Han- 

 nah's, near Crainesville, Tenn., is quite probabl)^ of this species. 



Several of our specimens indicate a size considerabl}^ greater 

 than the figure.
