HyprosERA (TERPSINOE ?) NovAE-CAESAREAE Boyer n. sp. 
At first sight this species might appear to be a variety of Hy- 
arosera (Triceratium) trifoliata Cleve, but a close comparison will 
show that the two are distinct. 
Triangular, sides concave, angles broad at the base, equally ai- 
vided into three projections, surface sparsely punctate. In Cleve’s 
species the angles are cuneate and the middle lobe or tooth is nar- 
rower than the two outer, while the punctae are quite evident except 
at the center of the valve. There is a marked difference in gen- 
eral appearance, the New Jersey form being much less robust than 
that from New Zealand. It is quite common in the deposit and 
is of interest, as there is no form similar to it except that from 
New Zealand with the exception of two specimens noticed by 
Mr. Heinrich Reis in clay found near Cold Spring, Long Island, 
which discovery, however, was antedated by that made in the 
Wildwood material. I have not seen Mr. Reis’ specimens, which 
he identifies as Zriceratum trifoliatum and do not know, therefore, 
whether the Wildwood and Cold Spring forms are identical.
