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

 shorter and very distinct.

 Collection at the Phila. Academj'.

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

 illustrated I regard as belonging to a GastrochcBna. Fig. 1 1 a 

 [10 a] ? shows the opening enlarged. Desha3^es figures a seem- 

 ingl}' similar tube as belonging to Gastrochcena ampidlaria Lam. 



"Conrad has described from Claiborne a Gastrochcsna larva. 

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

 in my collection for a long time named Gastrochcena subbipartita, 

 n. sp. It is characterized like Gastrochcsna 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.
