costse, and by the presence of well defined striae over the entire 

 surface of the whorls. In this last respedl, as well as in the 

 subangulated form of the whorls, it also differs from the Fjisus 

 scalariformis Nyst (Coquilles et Polypiers Fossiles, p. 504, pi. 

 XL, figs. 5a, 6), from Lethen, Belgium. 



Localities. — Alabama : Woods bluff ; Gregg's landing ; Bell's ; 

 lyower Peach Tree ; Cave branch : Knight's branch ; Chotflaw 

 corner ; Hatchetigbee. 



Type. — Probably somewhere in the Acad. Nat. Sci., Philadel- 

 phia.

Conrad's original description. — See vol. i, p. 209. 



As remarked in Proc. Acad. &c., this figure represents one of 

 the largest and most compadl varieties of the species. ' 'The labral 

 lirae are unusually well marked ; the carinal nodules are very 

 large but imperfecfth' defined." The specimen belongs to the 

 Lea Memorial Collecftion and was obtained by C. W. Johnson, at 

 Bell's landing. 



Lignitic localities. — Alabama : Hatchetigbee ; Woods bluff ; 

 Yellow bluff ; Chocftaw ; Bell's ; Tuscahoma ; Nanafalia.

Levifusus supraplanus, nov. sp., PI. 6, fig. 9. 



In a former report, (Bull. Am. Pal., vol i, p. 207), I consid- 

 ered this form as a variety of L. siiteri. Specimens in my own 

 colledlion, in the Universit3^'s, and in that of the Lea Memorial 

 at the Academy of Natural Sciences fail to show such similarities 

 with suteri as to warrant their specific identity with that species. 



St>ecific chara£lerization. — Size and general form as figured ; 

 spiral whorls about eight ; surface smooth and almost shining, 

 with lines of growth somewhat sinuous and irregular ; median 

 carination sharply defined, bearing about ten flattened spines,
