Specific charaBerization. — Size and general form as indicated 

 by the figure; whorls about six; surface above covered with a 

 great number of ver)^ fine revolving lines, with a trace of a large 

 revolving line just above the suture; below with somewhat coarser 

 alternating spirals and near the periphery showing one strong 

 raised line; umbilical carina without traces of dentition; lines of 

 growth on umbilical wall nearly vertical near the umbilical carina 

 but, just before reaching the whorl above, swinging forward 

 and truncated by a well-defined spiral sulcus. 



Locality. — Ala.: Bell's landing.

Discohelix verrili, nov. sp., (by Aldrich), PI. 11, fig's 9, a. 



Syn. Orbis rotella Aid., non Lea, Geol. Surv. Ala., 1886, Bull, i, p. 53. 



Aldrich has sent the following description of this new species, 

 not in our colledlions: 



"Shell of medium thickness, flattened above, with straight 

 side meeting the upper surface at quite an angle ; base ex- 

 tremely excavated, showing all the whorls which are six in 

 number. Surface of the whorls nearl}^ smooth, showing some 

 very fine radial lines of growth, the outer edge of each whorl 

 bordered by a raised and beaded rib, this line showing both 

 above and beneath. The flattened outer edge of the body whorl 

 bears a second beaded line above and two raised ones below near 

 base with two or three very faint lines between. The apex is 

 depressed below the plane of the top and the nucleus is smooth 

 and inverted. Aperture semi-quadrate, wider at the outside, the 

 whole aperture standing at an angle to the body of the shell; 

 interior is thickened somewhat at the intersedlion of the angles.
