32 CRETACEOUS GROUP 
SPHYRENA. 
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 MOLLUSCA. 
CEPHALOPODA. 
SEPIA. 
I possess several remains which correspond very nearly 
with the figures given by M. de Blainville of the Ruyn- 
COLITES, supposed to be the fossil beaks of Sepiz.
