currence to those in the red sandy ehi}'? as to suggest that, 
were the sands further oxidized and the calcareous shells dis- 
solved out, there would result exactly what is found in the 
surface sands. 
4. There are in the specimens from the superllcial deposits 
no indications of their having been waterworn. In Cardivvi. 
harrisi the angles are very sharp, so that if it had been trans- 
ported it must have been imbedded in rock. As the specimen 
is large, a powerful current w^ould have been required and 
there are no indications of such. 
For the above reasons the author considers the red clays 
and red sandy clays on the hills in the vicinity of Mt. Lebanon 
and Arcadia as oxidized Eocene. 
Fossils as casts in ferruginous sandstone have been found 
in Lincoln, ('hiiborne, and Bossier parishes. 
The Cockspeld Ferry beds. 
Conformably above the fossiliferous Lower Claiborne at St. 
Maurice, fig. 6, plate IX, are laminated non-fossiliferous clays 
or laminated sand and clay, dipping slightl}' south. These 
beds present different lithological phases, sometimes contain- 
ing more clay and little or no sand. 
The same beds are well exposed at Cocksfield Ferry, about 
halfway between St. Maurice and Montgomery, fig. 7, plate IX. 
At Montgomery, immediately below the Ja(!kson,* beds 
lithologically like those found in the upper part of the St. 
Maurice section and like those at (,'ocksfield Ferry are found. 
The section at Montgomery is represented in fig. H, plate IX. 
The dip at Montgomery is somewhat steeper than at St. Mau- 
rice. 
For these beds between St. Maurice ami Montgomeiy, com- 
ing between the Lower (Jlaiborne and the Jacksdii. I propose 
the local name of t'(>ck.\pel<I Fernj beds. In a general way 
they represent the Claiborne sands of Alabama, but it is not 
possible to limit precisely the Lower ('laiborne above or the 
Jackson below, and one cannot state exactly how much or 
what part of these be^ls represent the Claiborne sands. No 
beds bearing marine fossils and equivalent to the latter beds 
have been found in Louisiana.
