Description. — "Shell small, short elliptical in outline, v^rith 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 se&n." (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-
