Varietal characJerization . — Costse on body whorl about 20 

 in.stead of 15; 4 or 5 revolving lines or bands present on each 

 spiral whorl with interspaces marked by three thread-like raised 

 lines, the middle one the largest. 



So extremely different is this spiral ornamentation from that 

 of the specimen I formerly referred to a form of \ 'olutilit/ies, a 

 Midway type, that it is perhaps hazardous to refer this to the 

 same species. But the peculiar, oblique costation, nonconfor- 

 mable to the lines of the growth, the smooth apical whorls, the 

 fa(ft that the lower part of the columella and body whorls of 

 quercollis were gone and hence the generic position was not 

 certain, all tend to suggest a probable relationship between these 

 very different looking forms. 



Localities. — Ala.: Gregg's and Bell's landings.

Conrad's original description. — "Subfusiform, with longitudinal 

 narrow ribs and a few thick varices; volutions six, those of the 

 spire convex; regular, prominent revolving lines, six in number, 

 on the penultimate volution, eighteen or nineteen on the body 

 whorl, fine, and crowded near the suture and base; labrum striate 

 within; columella with three sinuous plaits, the upper one large 

 and thick.

In my Phila. Acad, paper (see above '^, I gave Conrad's in- 

 corre(5l reference to his plate and figure, i.e.: I wrote fig. 8, pi. 

 21, when I should have written fig. 8, pi. 20. Conrad's pi. 21,
