Crosswicks and Pensauken creeks. Clark enumerates 86 
species of inveriebrates, mostly molluscs, and Lewis Wool- 
man in his artesian well reports has added several others, as 
has also Mr. C. W. Johnson,* who points out their identity 
with the Ripley fauna of the Gulf region. Other remains 
include sharks’ teeth ; Foraminifera, of which 20 species are 
recorded by Bagg; tf echinus and other spines; Ostracoda ; 
gavial (?) teeth; dinosaurian bones; { etc. 
The exposure fronting on Raritan Bay near Cliffwood, N. 
J., and forming a bluff some thirty feet high northwest of 
Matawan creek, has been admirably described by Hollick,§ 
who records obscure crustacean and molluscan remains, 
from which Professor Whitfield identified eight species of 
molluscs, and enumerates twenty-six species of plants, of 
which ten were new. I have found some few molluscan re- 
mains here, occurring in the ferruginous concretions picked 
up on the beach, from which Professor Clark has identified 
the following: /donearca vulgaris Morton, Veleda lintea 
Conrad, Cardium sp., Turritella vertebroides Morton and 
one or two other species, new to the formation, not yet thor- 
oughly studied. 
I have nothing to add to the details of the exposure. It is 
capped with gravel and in places consists of regularly alter- 
nating beds of fine sand several inches thick and seams of 
comminuted vegetable matter an inch or two in thickness 
(pl. 56). These are replaced by alternating beds of clay 
and sand with lignite, and sparingly with greensand. The 
face of the bluff is almost entirely hidden as shown in J/, 
55, and while the majority of my plant remains have been 
collected from dropped boulders of clay, all have come 
from near the base of the exposure except the large cone 
(Seguoza sp.). These plant beds are some distance above 
the base of the formation, however, and their preserva-
