ii Aldrich, Eocene Fossii s 



A variety of Levifusus supraplanus Harris is also figured, 

 Plate IV, fig. 4, which rather connects the form with Fusus 

 {Levifusus) suteri nobis, seems to be di>tinet from other forms, 

 yet these species vary so a lot may go into one basket eventu- 

 ally. 



Levif7isus pagoda, Heilpr. , var. 

 Plate IV, fig's 5, 6 



Differs from all other forms described by its possessing two 

 raised, revolving lines, slightly tubercular. Specimen figured 

 is from Woods Bluff, Ala. It also occurs at Matthew's Land- 

 ing, Ala., in the Midway horizon, The variation in this and 

 other species of Levifusus are greater than generally recognized. 

 One form in my collection of this species has two rows of tuber- 

 cles at the periphery of the body- whorl, both equally prominent, 

 still another form has the single row at the periphery followed 

 below by five or more pairs of raised lines running in couples. 

 This form occurs at Yellow Bluff, Alabama River. Ala. 



Plate IV, fig. 7 is another form that may equal Levifusus 

 indenius Harris, I have no doubt several of these so-called 

 species will be united upon future study.

 tip and buried in the same. Three other whorls, flattened 

 above, ribs becoming spinose above ; revolving lines numerous.

Lyrischapa harrisi, nov. sp.

 rying eleven strong, elevated ribs which become spinous at
