ART. IX. — Descriptions of some Neio Species of Cretaceous Fossils. 



By Wm. M. Gabb. 



CHEMNITZIA, D Orb. 



C. Meekana. PI. 48, fig. 1. Shell fusiform; whorls six or seven; mouth nearly 

 half the length of the shell, a little the widest near the lower end ; surface marked 

 by prominent, longitudinal ribs. 



Locality and position. — From the white limestone of Prairie Bluff, Alabama. Col- 

 lection of the Academy. 



ACT^ONINA, UOrb. 



A. naticoides. PL 48, fig. 2. Shell globose; whorls three or four; spire very 

 slightly elevated ; surface marked by numerous revolving lines. 



Locality and position. — From the marl of New Jersey. 



There are two specimens in the Academy's collection ; one from Burlington Co., 

 N. J. The locality of the other is unknown. One specimen in my own collection is 

 from Mullica Hill. It was found with Exogyra costata, Gryphcea vesicularis, Rostellaria 

 pennata, Baculites, Natica abyssinis, &c 



The only fossil with which this could be confounded is Actceon concinna, Hall and 

 Meek, from which its wider mouth, as well as its two plates on the columella, 

 will serve to distinguish it. 



PHASIANELLA, Lam. 



P. punctata. PL 48, fig. 3. Shell elevated above, rounded below; whorls five; 

 mouth about two-fifths the length of the shell ; spire elevated ; surface marked by 

 numerous, minute punctations, arranged in revolving lines. 



Locality and position. — Mullica Hill, N. J., with the above. My own collection. 



STRAPAROLUS, Montf. (Euomphalus, J. Sow.) 



S. subplanus. PL 48, fig. 4, a, b. — Shell nearly flat above, subangular below ; 

 whorls two ; mouth subquadrangular, more rounded below than above ; surface 

 marking unknown. A cast.
