Locality. Gregg's Landing, Ala. 

 Decidely fusiform in aspect. 



LEUCOZONIA BIPLICATA, n. sp. PI. 5, fig. 15. 



Shell broadly fusiform ; whorls six nucleus composed of two smooth 

 whorls, those remaining covered with revolving, somewhat alternating 

 raised lines and strong longitudinal ribs, which give the shell an angular 

 appearance. Outer lip sinuate, thickened internally, finely crenated ; 

 columella bearing two erect, strong folds, the posterior one nearly twice as 

 large as the other, below these folds nearly straight. 



Aperture terminating in a short, open canal. A small umbilicus nearly 

 covered by callus. 



Locality. Matthews' Landing, Ala. 



BULBIFUSUS PLENUS, n. sp. PI. 6, fig. 7. 



Shell broadly fusiform ; whorls probably six, surface on upper whorls 

 with a few distinct revolving lines, which on the upper part of the body 

 whorl become faint ; body whorl swollen above, rapidly narrowing below, 

 where it is spirally striated with alternate raised lines; whorls thickened 

 and constricted at suture and suddenly rounded ; suture hidden in the 

 groove thus formed ; surface finely marked with lines of growth ; aperture 

 oblong-ovate, terminating in a rather broad canal, which turned to the 

 left ; outer lip slightly crenate within ; columella smooth, no perceptible 

 callus on posterior part. 



Locality. Bell's Landing, Ala. 



Resembles somewhat the Jacksonian species of Clavella, but its whorls 

 are few, spire low and canal recurved. The apex is worn, but appears 

 to be blunt.

Fusus inauratus, Con. Foss. Shells of Tert., p. 29. 



Fusus Fittoni, Lea. Cont. to Geol., p. 150. PL 5, fig. 156. 



Bulbifusus inauratus, Con. Cat., 1865. 



Figured to show its similarity to the species described below. 



BULBIFUSUS TUOMEYI, n. sp. PI. 6, figs. 12, 12 a. 



Shell large, bulbiform ; whorls seven ; spire moderate ; body whorl 

 very large and globose, flattened above and slightly concave, contracted
