Tho forcfioing I'xposiin- is 100 tVd in \crtical hi-ighl. As this is the 
last section northward along this line \vr nder the above limestone to 
the Jackson beds till the fossils have been studied. 
In last November I visited the locality in whieli this sec- 
tion was made, and found the limestone composed of O.sirea 
xelhvforiiiis and Anomia ephippoides^ which of course put it 
into the Lower Claiborne: and as the gra}" clays are conform- 
ably just below the limestone, they must also be referred to 
the Lower Claiborne. 
The '•'■Upper Liyni tic"' of Dr. Lerch. This author has de- 
scribed a series of Jignitic clays wliich he states overlie his 
'•'Marine Claiborne," and to which he has given the name of 
"Upper Lignitic." Part of his Upper Lignitic, as exposed ten 
miles northwest of Winnfield, undoubtedlj' belongs in the 
Lower Claiborne, for it is there overlaid by strata bearing 
Lower Claiborne fossils. But I am not certain that the strata 
in other localities presenting the same lithological appearance 
and designated by Dr. Lerch as the Upper Lignitic, occupy 
the same stratigraphic position. At Columbia the lignitic 
strata probably are not Lower ( ^aiborne but represent what I 
have called the Cocksfield Ferry beds. The lignitic strata 
about three miles south of Kosefieldf lie at the base of the 
Vicksburg, and most probably they are intermediate between 
the Jackson and that stage. 
The red clai/.s und red xandi/ chn/s in flie rii-inifij of Mi . Ijeb- 
aiioii and Arcadia. In northern Louisiana many hills are 
capped by deposits of red sandy cla^'s, which in the vicinity 
of Mt. Lebanon, Homer, and Arcadia contain fossils that are, 
excepting one species, identical with those of the underlying- 
Lower Claiborne. The exception is a new Cardiidn, to which 
I have given the name of C. harrisi. The species found in 
these deposits are :
