Fusus Pearlensis,* n. sp. PL 3, fig. 17, a. b. Shell, small, 

 fusiform, with eight whorls, surface covered with prominent revolv- 

 ing ridges and longitudinal folds; suture, deeply impressed; whorls, 

 convex ; apex, pointed, smooth, first whorl below also smooth ; 

 center of each volution almost carinate ; body, whorl with four 

 prominent revolving ridges, nodular, situated on the central part of 

 the whorl, less prominent ones above and below ; lines of growth 

 give the shell a pitted appearance; aperture, nearly half the length 

 of the shell ; canal, straight, contracted ; columellar lip, with a re- 

 flected callus and plicate-dentate, its whole length ; outer lip, in- 

 curved, plicate within. Length, y 6 ^ ; breadth, inch.

Scalaria Whitfieldi, n. sp. PI. 3, fig. 18. Shell, solid, turrited, 

 lustrous white ; whorls, probably six, rapidly tapering, round; ribs, 

 numerous, rather far apart ; body whorl with one raised transverse 

 line near the base, microscopic revolving lines between the ribs 

 upon the body of the shell ; ribs, very solid, thick, rough on the 

 edges, apparently double on the body whorl, bending toward the 

 mouth at the suture ; aperture, round ; outer lip, reflected and very 

 heavy, projecting slightly at the base. Length, — ? breadth ^ of 

 an inch. 



Locality, Red Bluff, Miss. 



The apex and part of the spire are missing from the only speci- 

 men ; this species is remarkable for the absence of all revolving 

 lines but the one at the base of the body whorl. 



Cassidaria brevidentata, n. sp. PL 3, fig. 20. Shell, oblong- 

 oval, whorls seven ; suture, channeled ; surface, covered with fine 

 revolving striae ; coarser, distant lines upon the body whorl, 

 giving the shell the carinated aspect of the genus ; lines of growth 

 fine, a few coarser ones showing on the line of the tubercles ; apex, 

 smooth ; whorls of the spire carinate and slightly tubercled; a row 

 of upright longitudinal nodes on the shoulder of the body whorl, 

 none below ; a single, strong varix on the body whorl ; aperture, 

 ovate ; inner lip, spread over the whorl, with three plications on 



*This may be the species mentioned by Meyer, Am. Jour. Science, June, 1885, un-
