32 CRETACEOUS GROUP 



Sphyilena. 



PL xii, fig. 1. 



Some remains of this remarkable genus of fishes, have 

 been found in the blue marl of Monmouth county, New 

 Jersey. Part of a jaw, with several teeth, is in the pos- 

 session of William Cooper, Esq. ; and the annexed draw- 

 ing of a large tooth, is from a specimen in the cabinet of 

 the Academy of Natural Sciences. 



Impressions and scales of fishes have been repeatedly 

 observed ; but the friability of the matrix in which they 

 occur, has prevented their being carefully examined. 



Masses which appear to be Coprolites are not unfre- 

 quent. 



A solitary tibia of a bird belonging to the genus Scolo- 

 pax, was found in friable green marl near Arneytown, 

 New Jersey. It is preserved in the Academy of Natu- 

 ral Sciences.. 



ANIMALIA MOLLUSOA. 



CEPHALOPODA. 



Sepia. 



I possess several remains which correspond very nearly 

 with the figures given by M. de Blainville of the Rhyn- 

 colites, supposed to be the fossil beaks of Sepiap.
