having a shallow sinus on the dorsal valve, while the Alabama shell is 

 described and figured without this feature. I do not, therefore, consider it 

 as properly belonging to the State fauna.

Mr. Gabb states that he has seen this species from the Cretaceous marls 

 of New Jersey, and therefore he considers it as a Cretaceous species, remark- 

 ing that D'Orbigny is incorrect in placing it in the Lower Eocene. Dr. 

 Morton's specimens were from the calcareous strata of South Carolina, 

 which is considered as Eocene, although at the time Dr. Morton described 

 the species it was supposed to be Cretaceous. He also states that Mr. 

 Conrad had at a later time obtained it from ^^ strata below Claiborne, Ala." 

 This would also bring it into the Eocene, Mr. Meek, in his check-list of 

 Cretaceous MoUusca, does not include this as a Cretaceous species, and, 

 although Mr. Conrad does not include it among the Eocene Terebratulidae 

 in his Smithsonian Institution check-list of that formation, he does subse- 

 quently in a later list published in Vol. I, Am. Jour. Conchology. I do 

 not know what Mr. Gabb may have seen from New Jersey to identify as 

 belonging to this species, but I certainly have never seen any shell or cast 

 of shell from New Jersey that I should consider as belonging to it. In 

 order that it may be identified if found, I have given a figure, enlarged to 

 twice the natural size, of a specimen of undoubted authenticity, from the 

 white limestones of the Eocene of South Carolina, near Charleston, for 

 comparison.
