the specimens); suture distinct; mouth linear, cokimella slightly 

 recurved and with three small oblique folds, inner lip slightlj^ 

 thickened at the upper part; surface marked by long-itudinal 

 ribs, (about eleven on the body whorl), crossed by numerous 

 revolving lines. 



''Dimensions. — Length of the body whorl of the smallest, but 

 most perfect specimens, .6 in.; width of ditto, .4 in.; length of 

 mouth, .55 in." 



The locality from which Gabb cites this species is ' ' Hardeman 

 Co., Tenn." and its geological horizon, " Ripley Group. " 



This is characterized by a strong subsutural row of short 

 tubercles located at the upper termination of the well defined 

 ribs. Below this row the body whorl has a rather prominent 

 shoulder; on the shoulder and below there are three rather 

 strong rows of tubercles, while the revolving lines below carry 

 only slightly thickened nodes as they cross the ribs. The colum- 

 ellar plaits are normally: one strong one, with a weaker one above; 

 between these two there is often a small one, and there are 

 several smaller ones above the weak one just mentioned.

Conrad's original description. — "Subfusiform; volutions seven; 

 body whorl longitudinally ribbed ; ribs angular, acutely tubercular 

 on the upper part; revolving lines prominent, acute, more salient 

 where they cross the ribs, about twenty-seven in number; whorls 

 of spire slightly convex, five series of tubercles on last volution; 

 aperture narrow-elliptical; inner lip with a thin, wide deposit; 

 columella with three plaits, the superior one obsolete or very 

 small. 



' ' Length i ^ inches. Diameter f^ inch. 



"A beautiful species resembling V, crenulata Lam., or more 

 nearly V. ambigua, but it has a more fusiform shape than either, 

 a norrower aperture and dissimilar folds on the columella."
