ever from any species previously noticed, being much smaller and 
of more slender habit. The external markings are unknown. The 
specimen is from the Lower Green Marls at Lenola Station on the 
Long Branch Division, Pennsylvania Railroad in Burlington Co., 
New Jersey. The type is in the collection of the Academy of 
Natural Sciences of Philadelphia. Collected by Mr. Lewis Woolman 
of Philadelphia for whom it is named. 
Cerithium Pilsbryi n. sp. 
Shell elongated and slender; volutions numerous, number not 
determined, very gradually expanding with additional growth; 
apex and aperture unknown. Volutions slightly convex between 
sutures, and ornamented by a band of small oblique nodes immedi- 
ately below the suture ; also by aseries of larger vertical folds which 
extend across the exposed part of the volution, below the upper band 
of nodes, and numbering something more than one half as many to 
the volution as the nodes above. There are also very fine spiral 
strie almost too fine be seen without magnifying. The lines of 
growth are fine but distinct, and take a broad sweeping backward 
curve between sutures. Apical angle fifteen to eighteen degrees. 
This species is a new type for the New Jersey cretaceous, and I 
know of none of the same type in the rocks of this age in North 
America; while in the Cretaceous of Palestine there are several 
species already described. The one most nearly like this being that 
described in the Bulletin Am. Mus. Nat. Hist. for December, 1891, 
figured on Pl. IX of Vol. III, figs. 11 and 12, under the name 
Cerithium Conradi ; the point of difference between them being the 
exact reversal of the lines of nodes, the upper one here being small 
while on that one it is the largest. These specimens consist of concre- 
tionary matrices, in what appear to have been Coprolitic bodies, in 
one of which there are fragments of several species of molluscs repre- 
sented. They are also from the Lower Green Marls at Lenola, N. J. 
Collected by Mr. Lewis Woolman, and are deposited in the collec- 
tion of the Academy of Natural Sciences, Philadelphia. 
Another Cerithium-like shell oceurs with the above, but is too 
imperfect for specific description. It presents characters which 
would most likely ally it to Cerithiopsis. There are imprints of por- 
tions of six volutions remaining in the matrix showing three lines of 
nodes on each yolution, increasing in size from above downward. 
This also is an undescribed species. There is also an internal cast 
of a species of Anchura or Rostellaria, which differs from any
