Section on Ferry Road, Claiborne, Ala., White Limestone.

3. Gray laminated clays irregularly interstratified with 



yellow sands. In the lower portion of the stratum 

 are leaf impressions, and a variable streak of lignite 

 which in places attains a thickness of two inches.--. 8 feet. 



4. Claiborne Ferruginous sands 4 feet. 



Indurated sandy ledge (1 of Aldrich)4 



No. 3 of this section seems to be developed only at this 

 point, as across a gully not more than a hundred yards down 

 the river the clays lose both their laminated and lignitic char- 

 acters and the whole stratum becomes a mottled gray and red 

 argillaceous sand which is non-fossiliferous ; the ferruginous 

 sands become about six feet thick. An examination of four or 

 five other localities where the ferruginous sands are exposed 

 failed to show any association with lignitic clays. 



Descriptions op New Species. 



Verticordia Eocensis nov. sp. 



Shell rotund, beak recurved, elevated and striate, substance 

 of shell rather thick, lunule obscure, one prominent cardinal 

 tooth, lateral teeth oblique, margin dentate and crenulated 

 between dentations ; nacre brilliantly pearly ; muscular im- 

 pressions two, profound ; pallial line obscure ; closely ribbed ; 

 ribs about 16, crenulate, radiating regularly from the beak and 

 slightly recurved. 



Length -25 Breadth -25 Height -06 



* This bed seems to be the natural horizon of these two fossils, for while they 

 are very abundant here, they are seldom found in the ferruginous sands proper. 



f Described from Jackson ; has not yet been found in ferruginous sands but 

 occurs occasionally in No. 1 of Aldrich's section.
