20 PROCEEDINGS OF THE ACADEMY OF [Jan, 



Straparolus subplanus Gabb, Jour. Acad. Nat. Sci., IV, 2 ser., 299, pi. 48, figs. 4a, b, 1860. 



This will probably prove to be a synonym of S. lapidosus Mort. 

 Straparolus deplanatus Gabb, jhb. 



The type of this species is what Gabb figured by mistake for the 

 type of Delphinula lapidosa Mort. (Jour. Acad. Nat. Sci. IV, 2 ser., 

 300, pi. 48, figs. 5a, b. With the specimen there is an original label 

 in Gabb's hand\^Titing, " Sti'aparolus deplanatus Gabb, Cretaceous, 

 Ala." On the specimen is wTitten the word '' type." This seems 

 to be a good species, the characters of which are well shown in 

 the figure referred to. It is more depressed than S. lapidosus, the 

 body whorl being almost uniforml}^ rounded above and below. 

 While practically an internal cast, the spire still has some of the shell 

 (altered to calcite) remaining, which shows a slight crenulation below 

 the suture. The specimen evidently came from Prairie Bluff, Alabama. 

 I have been unable to find a description.
