Heilprhi' s original description. — "Shell bucciniform, of about 

 seven volutions; the whorls roughly plicated; the folds on the 

 body whorl appearing as shoulder nodules; dentiferous sulcus 

 well pronounced, followed by about five impressed revolving 

 lines, which slightly crenulate the margin of the outer lip; re- 

 volving lines on the body whorl above the sulcus almost obsolete; 

 aperture slightly exceeding the spire in length; columella callous; 

 suture deeply channeled.

Pseudoliva sp., ^ PI. 9, fig- 22. 



In the material collected from the railroad cut, i^ mi. N. E. 

 of Clayton, there is an imprint of a Pseudoliva showing the 

 features represented by fig. 22, i. e., a very pointed spire, minute 

 or not strong nodes on the shoulder of the body whorl, a strong 

 spiral channel rather high up on the body whorl and traces of 

 spiral lines below. The vertical lines and the spiral lines on 

 the shoulder are lines of shading only, the original specimen is 

 of too coarse material to show such markings. More material 

 must be collected before we can decide certainly whether this is 

 or is not a variety of P. tuberculifera Con. On first sight it ap- 

 pears very distinct, but when the great variations of P. vetusta 

 are borne in mind one becomes cautious in proposing new spe- 

 cific names. The figure is natural size.
