Re?narks. — This shell is quite fragile, the body whorl break- 

 ing awa}^ from the spire. Prof. Harris figured the spire of this 

 species under Aesopus erectus (Proc. Acad. Nat. Sciences, Phila., 

 1896, p. 476, pi. 21, fig. 3), which it resembles, but later on 

 states it is not the same. The Ala. Museum has three specimens, 

 and there are two broken ones in my cabinet.
