CADULUS CORPULENTUS, n. sp. PL 3, fig. 5. 



Small ; inflation near the middle, short and stout, not compressed ; 

 smaller aperture elliptical with simple margin. 

 Locality. Red Bluff, Miss.; common. 



CADULUS JUVENIS, n. sp. PI. 3, fig. 4. 



Small ; inflation near the middle ; slender, not compressed ; smaller 

 aperture forming an ellipse, one side of which is flattened. 

 Locality. Jackson, Miss.; not rare. 



TEINOSTOMA ANGULARIS, Meyer. PL 1, figs. 9, 9a. Am. Jour. Sci., 

 1885, XXIX., p. 463. 



Lenticular; whorls three, rapidly increasing in size, last whorl carina- 

 ted ; base slightly convex, nearly flat ; columellar part thickened ; mouth 

 rhombical. On both sides of the carina several impressed spiral lines 

 crossed by very minute radiating striae. Last whorl with an indistinct 

 spiral fold near the suture. 



Locality. Claiborne, Ala. 



TEINOSTOMA SUBROTUNDA, Meyer. PL 2, figs. 26, 26a. Am. Jour. 

 Sci., 1885, XXIX., p. 463. 



Discoid ; margin rounded ; umbilical region covered and thickened by 

 callus ; whorls four, rapidly increasing in size ; smooth, except some 

 faint revolving lines ; suture indistinct ; aperture quadrate-elliptical . 



Locality. Claiborne, Ala. 



TEINOSTOMA VERRILLI, Meyer. PL 2, figs. 27, 27a. Am. Jaur. Sci., 

 1885, XXIX., p. 463. 



Discoid ; umbilical region covered and thickened by callus ; margin 

 angular, though not carinated, polished; suture entirely indistinct, so 

 that the number of whorls can not be counted ; base regularly rounded ; 

 aperture trigonal-elliptical. 



Locality. Jackson, Miss. 



Related to the preceding species, but distinguished by the more angular 

 margin, and the entire absence of sculpture. The first difference implies 

 also the different form of base and aperture ; the second difference, the 

 indistinctness of the suture.
