and prominent, basal margin slightly arched. 



Claiborne, Alabama. 



This rare species is allied to F. elongata Desh. , but is proportionally 

 shorter and very distinct. 



The very much broken tj-pe is still in the Conradian Eocene 

 Collection at the Phila. Academy.

Me3^er remarks regarding this form : "The burrow herewith 

 illustrated I regard as belonging to a Gastrochcsna. Fig. 11 a 

 [10 a] ? shows the opening enlarged. Deshayes figures a seem- 

 ingly similar tube as belonging to GastrochcBna a^npullaria Lam. 



"Conrad has described from Claiborne a Gastrochana larva. 

 Besides, I have had a specimen of another species from Claiborne 

 in my collection for a long time named GastrochcBna subbipartita ^ 

 n. sp. It is characterized like GastrochcBna bipartita Wat, by an 

 umbonal furrow dividing it into two parts. I have not illustrated 

 the species as it is possible better material may be obtained." 



We herewith copy Meyer's illustrations as so far we have 

 found no good specimens of the species.
