Locality and position. — Green marl, €rosswicks, N. Jersey. Collection of the 

 Academy. 



FUSUS, Lam. 



F. retiper. PI. 48, fig. 11. Shell pyriform; spire slightly elevated; mouth wide, 

 outer lip slightly reflected (?) ; surface crossed by two series of impressed lines so as to 

 present a pavement-like appearance. 



Locality and position. — Mullica Hill, N. J., with Actasonina nalicoides, Phasianella 

 punctata, &c. My collection. 



RAPA, Klein. 



R. elevatA. PL 48, fig. 12. Shell subfusiform ; spire rather more elevated than 

 in the majority of species of this genus ; mouth angular, patulous ; surface apparently 

 marked by revolving striae ; canal unknown. A cast. 



Locality and position. — Brown marl, Burlington Co., N. J. The canal of this shell 

 has probably been prolonged, but the specimen is so broken that it is impossible to 

 determine. Collection of the Academy. 



SCONSIA, Gray. 



S. Alabamensis. PI. 48, fig. 13. Shell subfusiform ; mouth two-thirds the length 

 of the shell; surface markings unknown; whorls five; the cast presents the remains 

 of longitudinal ribs. This shell can be readily distinguished from any other heretofore 

 described in this formation by its single, strongly marked varix. 



Locality and position. — White limestone, Prairie Bluff, Alabama. Collection of the 

 Academy. 



CANCELLARIA. 



Cancellaria Alabamensis. PI. 48, fig. 14. Shell wide; spire low; whorls four; 

 mouth expanded ; three or four folds on the columella.

PURPURA, Brug. (MORE A, Con.) 



P. (Morea) naticella. PI. 48, fig. 15. Shell patulous ; whorls four; mouth wide; 

 surface marked by longitudinal ribs, crossed by lighter revolving lines. A cast. This 

 species resembles M. cancellaria, Con., but can be distinguished by its more elevated 

 spire, and its more robust form. 



Locality and position. — Brown marl, N. J. Collection of the Academy. 



BULLA, Klein. 

 B. macrostoma. PL 48, fig. 16. Shell subglobose ; whorls two or three; mouth 

 very wide ; surface unknown ; on the cast there are faint traces of longitu- 

 dinal markings, probably lines of growth. A cast.
