it proved to be like the species figured. There is some confusion here 

 which needs further investigation. 



CYPR^EA SMITHII, n. sp. PI. 5, fig. 3. 



Shell oblong-ovate, rather flat, surface smooth ; labrum crenulate 

 within, smooth on the base and flattened, reflected somewhat and raised 

 above base of shell ; aperture slightly crenulate within, expanded below. 



Locality. Gregg's Landing, Ala. 



Named in honor of Dr. Eugene A. Smith, of Tuscaloosa, Ala. 



CASSIS (SEMICASSIS) SHUBUTENSIS, Aldr. PI. 2, figs. 5a, b. 

 Cassis (Semieassis) shubutensis, Aldr. J. C. S. N. H., July, 1885. 



CASSIDARIA BREVIDENTATA, Aldr. PL 1, fig. '20. 



Cassidaria brevidentata, Aldr. J. C. S. N. H., July, 1885. 

 Cassidaria earinata, Lam. (Aldr.) J. C. S. N. H., July, 1885. 



In the article published in 1885, the first-mentioned form was given a 

 new name on account of a strong varix, and the second form given 

 Lamarck's name. Upon comparison with the French shell, I have found 

 differences enough to place our shell in another species, and unite it to 

 C. brevidentata, Nobis, although it has no varix and is much more 

 ponderous. 



CASSIDARIA DUBIA, Aldr. PL 1, fig. 21. 



Cassidaria dubia, Aldr. J. C. S. N. H., July, 1885. 



NATICA RECURVA, n. sp. PL 5, fig. 10. 



Shell large, globose, smooth, whorls six, spire low ; suture channeled, 

 that part of the whorls within this groove concave, rising to a shoulder. 

 Body whorl very large, flattened on upper part, abruptly rounded below 

 the umbilicus ; aperture semilunar, rounded anteriorly and narrowed at 

 the posterior part ; callus thick, spreading over the body whorl and par- 

 tially covering the umbilicus. Umbilicus large, deep, striated within, a 

 thickened callus or rib proceeding from the lower edge of the outer lip, 

 and rounding into the umbilicus. 



Locality. Lisbon, Ala. 



The type shows on the body whorl traces of numerous revolving color 

 lines.
