74 CRETACEOUS GROUP 
Krie, Alabama. I have a small individual from New Jer- 
sey. It has never been found attached. 
Dr. Goldfuss, in his Petrefacten, pl. lxx, fig. 13, gives 
a fossil which he calls SerpuLA sexsulcata, from the Up- 
per Palatinate. It is obviously congeneric with Ha- 
mulus. 
CRUSTACEA. 
Astacus, Lam. 
A small species, with most of its parts entire, was ob- 
tained at the canal excavations in Delaware. 
CANCER, Lin. 
Dr. Van Rensselaer* has described and figured four 
fragments, chiefly claws, from the vicinity of Sandy Hook. 
Similar remains of several distinct species are contained 
in the cabinet of the Academy, but mostly too imperfect 
to allow of a precise classification. 
ANAMALIA RADIATA. 
ECHINODERMATA. 
ASTERIAS. 
I have seen but a few obscure fragments of this genus, 
from the calcareous strata of South Carolina.
