Teinostoma reguiaris, n. sp. PL i. Figs. 21-2. 



Shell small but larger than the ordinary species of this 

 genus ; whorls five, depressed above ; periphery rounded ; sur- 

 face covered with fine lines which are croSvSed with lines of 

 growth. Under a glass the intersections give the surface a 

 beaded appearance ; a depressed space just below the suture. 

 The base has coarser lines with a smooth space around the um- 

 bilicus which is open ; aperture oval. Diameter 4 mm. 



Locality. — Pugh's Branch of Satilpa Creek, Clark Co., Ala. 

 Gosport Sand. 



Type. — Ala. Museum at University, Ala. 



Remarks. — This little shell may possibly belong to the sub- 

 genus Omphalius of Chlorostoma but it seems closer to Teinos- 

 tofua. 



Ancillopsis Tuomoyi, n. sp. PL i. Figs. 23, 24. 



Shell solid, thick, oblong, smooth and shining ; whorls 5-6 ; 

 spire rather pointed ; the first four whorls small, the others rap- 

 idly increasing ; a swollen callus reaching above the body whorl 

 and also covering the front of this whorl and lapping over the 

 back of this whorl. A deep suture reaches the aperture where 

 it is rather wide ; a few irregular lines of growth are visible ; 

 aperture about three-fourths the length of the shell, oblong-ovate; 

 columella smooth, concave. The basal groove shows strongly at 

 base, but only showing a short distance up where it is covered by 

 the enamel. I^ength 28 mm ; breadth 21 mm. 



Locality. — Bell's Landing, lower bed, also one example from 

 Gregg's Landing, Ala. The lower bed at Bell's Landing is the 

 same bed as at Gregg's Ldg. Type from Bell's Landing, lower 

 bed. 



Type. — Ala. Museum of Nat. History. 



Remarks. — This species resembles Macron in some respects 

 but is evidently an Ancillopsis. 



Nassa pleona, n. sp. PI. i. Figs. 25, 26. 



Shell small, nuclear whorls broken off. Four remaining 

 whorls carry longitudinal ribs that are crossed by two spirals,
