Description. "Shell small, short elliptical in outline, with a 

 short pointed spire and proportionally long body volution ; volu- 

 tions probably about four, ventricose, largest above the middle 

 and attenuate below; aperture large, elongate elliptical, widest 

 above the middle and narrow below. Columella moderately 

 strong, marked by two distinct and distant plications below the 

 middle of the aperture ; surface of the shell so far as can be seen 

 on the inside of the cast of the outer volution in one of the type 

 specimens, marked by a few spiral ridges and by distant vertical 

 plications or folds, but which are not transmitted to the internal 

 cast in any of the individuals seen." (Whitfield.) 



Remarks. Internal casts from several horizons have been 

 referred to this species with more or less doubt, and the true 

 relationships of these various forms can never be properly de- 

 termined until the external features of the shells are better un- 

 derstood. One internal cast from the Cliffwood clay (pi. xcvi. 

 fig. 7) has the form of this species but with evidence of but a 

 single columellar fold. It is accompanied by an impression of a 

 small portion of the exterior of the shell which shows that there 

 was a slight thickening of the outer volution at least, just be- 

 neath the suture forming a very narrow revolving shoulder be-
