Pleurotoma anita, n. sp. PI. 2, fig. 3. Shell, bucciniform, 

 elevated, carinate, contracted above the shoulder; whorls of the 

 spire ornamented with a series of longitudinal nodes, crossed at 

 irregular intervals with raised lines ; apex, smooth, pointed ; 

 sculpture, coarse ; body whorl, shouldered, shoulder bordered by 

 a series of several fine tranverse lines between the heavy raised 

 ones; lines of growth, fine and numerous; aperture, oblong-ovate; 

 canal, short, rather open, and slightly twisted ; labrum, smooth in- 

 side, wavy in outline ; sinus, deep, broad, and rounded ; labium, 

 smooth, reflected below. Length, inches. 



Locality, Red Bluff, Miss. 



This species resembles P. Heilprini, nobis, but differs from it by 

 the lack of the constriction of the whorls, its coarser sculpture, 

 and strong nodes upon the body whorl. 



TURBINELLA (CARICELLA) RETICULATA, n. sp. PI. 2, figS. 4, a. b. C. 



Shell, pyriform, variable, moderately thin, with revolving raised lines 

 covering the whole surface, crossed longitudinally by finely raised 

 lines of growth ; lines alternately fine and coarse ; suture, impressed ; 

 spire, cancellated ; apex, decorticated in all the specimens. 



Whorls varying from roundly globose (Fig. 4, a. ) through the 

 form (4, b.) to a constricted form (Fig. 4, c), the upper part 

 concave, making the body whorl obtusely angular ; base, pro- 

 longed, strongly twisted ; aperture, oblong ; labium, curved, with 

 four equidistant plaits about the center ; outer lip, sharp, smooth 

 within. Length, iy^ inches ; breadth, variable. 



Localities, Red Bluff and Shubuta, Miss. 



Cassis (Semicassis) Shubutensis, n. sp. PL 2, figs. 5, a. b. Shell, 

 rather thin, oblong-oval; whorls six, convex, the surface with re- 

 volving lines ; suture, distinct ; apex, pointed ; spire, elevated, the 

 first three whorls nearly smooth, the next two slightly carinate ; 

 body whorl, with a sharp nodulous line on the upper part, nodes 

 running transversely, with another finer nodulous line above; cen- 

 ter of body whorl, with a strongly raised line, a lesser one above, 

 with fine close set ones between ; below the center are four raised 

 lines, with finer ones between ; beak, nearly straight, the outer lip
