Type, specimen figured mid locality. — In Paleont. Mus. , Cor- 

 nell Univ., from Lisbon, Ala. 



Horizon. — St. Maurice Eocene. 



Astarte neuseana, n. sp., PI. 32. Fig. 13. 



Specific characterization. — General appearance high and 

 acuminate as figured ; surface with faint, fine concentric striation 

 and with half a dozen or more broad undulations from the medial 

 portion basally, increasing in strength peripherally ; lunule deep, 

 about half the length of the anterior margin ; escutcheon less 

 sharply defined and slightly less in length. 



This is very different from anything else with which we are 

 acquainted in the Eocene of our Southern States. It seems like 

 a rather small, elevated arata from the Miocene. 



The only specimens we have are in form of imprints in a 

 a porous, silicious limestone from the vicinity of Rocky Landing 

 on the Neuse River, North Carolina.

Lea's original description. — Shell triangular, rounded below, angul- 

 ar above, compressed, inequilateral, concentrically and widely striate; 

 beaks elevated, pointed ; lunule large, lanceolate ; cardinal teeth small, the 

 posterior furnished with a long, straight lateral tooth ; cicatrices scarcely 

 visible ; margin entire ? 



Diam. 1-20, Length nearly .1, Breadth nearly .1 of an inch. 



The species at first sight might easily be taken ior pari'a. The mi- 

 croscope will, however, show very characteristic differences. It is less 

 angular above ; transverse strise are much farther removed ; it might be 

 said to be sulcate. All the specimens I have (five) are without a crenu- 

 lated margin. More perfect specimens may, nevertheless, exhibit this 

 character. 



Type. — This seems to be No. 5225 of the Lea Coll., Phil. 

 Acad. Coll. 



Horizon. — Claiborne and St. Maurice stages.
