CEPHALOPODA OF THE CRETACEOUS MARLS. 279 
existed within the limits of the State, as a single fragment of a large sized 
individual comes to me among the collections made by Prof. Reiley trom 
Holmdel, and is from the Lower Marls. The fragment is less than 2 inches 
in length, but is about 24 inches in its greatest transverse diameter, by 
nearly 14 inches in its shorter diameter. The fragment is apparently 
from within the septate portion of the shell, as it bears markings of the 
septa at each extremity, but in a condition altogether too imperfect for 
description. However, there is on each side of it a single one of the 
large inflated node-like undulations which characterize the species, through 
the highest part of which the shorter diameter of the specimen is nearly 
one-half greater than at a point below between this and the next node 
below. There have probably been other septa within the length of the 
fragment, but they are-entirely invisible in detail from the condition of 
preservation, although one of them appears to be obscurely indicated by 
an irregular thickened line near the middle of the length, the undula- 
tions on the side of the shell extending entirely across its width and 
modifying one of the edges. In crossing the side of the specimen it forms 
a deep downward curve in the middle, with corresponding deep but still 
broader depressions above and below it. _ The transverse section of the tube 
appears to have been nearly or quite symmetrically oval. 
It is possible I may be mistaken in the specific relations of this frag- 
ment; if it is not B. asper it must be an undescribed species, as none other 
described possesses the features which this one presents.
