A. Tuomeyi, Coz. 
Ovato-turbinate, with revolving lines distinct on the lower half and obsolete 
above on the body whorl; shoulder with distant prominent acute spines; 
between the spines and suture the side is flattened, swelling a little near the 
suture, and has a few revolving raised unequal lines; penultimate whorl con- 
cealed by the callous, above which the whorls are finely tuberculated and 
somewhat turrited; columella with 2 prominent plaits and 3 obsolete ones. 
Length 14 inch. 
Locality. Bashia creek, Clarke co., Alab. i 
I have given Mr. Tuomey’s name to this interesting shell which was originally 
referred by him to V. Sayana with doubt. Mr. Tuomey says the group of fossils 
in this locality are very distinct from those of Claiborne, and I have no doubt the 
deposit will prove to be an upper bed of the Eocene which may, when the fossils 
are all collected, be found to contain some of the species of the Older Miocene as 
it occurs at Vicksburg, Miss. The Athleta Tuomeyz, though a very distinct 
shell, is related to a Miocene fossil of Dax, (A. rarispina,) which is an abundant 
species. The genus appears to have no living representative.
