rupted by the body; pillar strong, slightly concave; lower hp meet- 

 ing it at a sUght angle and produced beyond it so as to cover the um- 

 bilical depression; base moderately convex, imperforate; surface 

 sHghtly granulate, probably due to minerahzation. Maximum 

 diameter, 4; minimum diameter, 3; height, 2.5 mm. 



Locality. — Station 7074, on the west bank of Fhnt River, 7 miles 

 southeast of Bainbridge, Decatur County, Georgia, at Hale landing, 

 in coralliferous chert; Vaughan, Cooke, and Mansfield, 1914. U. S.

LIOTIA (ARENE) HALENSIS, new species. 



Plate 88, fig. 4. 



Shell small, solid, turbiniform, of about three whorls, the suture ap- 

 pressed, indistinct, with a minute spiral beaded line in front of it; in 

 front of this are two or three fine simple spiral tlireads with siightlv 

 wider interspaces; in front of these are three much stronger simple 

 spirals, on the anterior of which the suture is laid, the interspaces 

 wider and channeled. A fourth similar cord, forming the periphery 

 of the base, enters the aperture just below the sutural commissure. 

 The base is shghtly flattened and sculptiu-ed with four or five simple 

 cords, with slightly wider interspaces, both diminisliing in size toward 

 the pillar. The umbihcal region is imperforate; the aperture is sub- 

 circular, shghtly crenulated on the outer hp in harmony with the 

 sculpture; the pillar hp thickened and somewhat angular outside of 

 the aperture, where it meets the lower hp. Height, 2; maximum 

 diameter, 3 mm.

LIOTIA? PERSCULPTURATA, new species. 



Plate 8G, fig. 5. 



Shell small, turbinate, with three or more rapidly increasing 

 rounded whorls, separated by a deep but not channeled suture; 

 apex concealed by matrix; last whorl sculptured by about 15 strong 

 closely beaded subequal spiral cords, separated by subequal chan- 

 neled interspaces, both evenly distributed over the whole whorl; the 

 interspaces are axially sculptured by sharp, elevated, equal lamellae 

 or imbrications about five to a milhmeter, with equal interspaces and 

 uniformly distributed; aperture circular, the inner margin thick and 

 smoothly bevelled to the outer edge, the throat smooth, the base of 

 the whorl imperforate. Height as figured, 65; diameter, 7 mm. 



Locality. —St2iiioi\ 3383, from a fossil coral reef at Little Horse- 

 shoe Bend, just below the mouth of Blue or Russell Spring on Ffint
