DESCRIPTION OF SPECIES IN THE NEWFOUNDLAND GRIT FAUNA. 
COELENTERATA. 
ANTHOZOA. 
ZAPHRENTIS sp. undet. 
In the Newfoundland locality of this formation specimens of horn 
coral are not of infrequent occurrence. All the specimens observed 
are imperfect casts of the cup, which retain neither specific nor generic 
characters sufficient for identification. All may be provisionally re- 
ferred to the genus Zaphrentis. The largest specimen observed has 
a maximum diameter of 45 mm.

Several specimens of a species of Stropheodonta from Newfound- 
land are evidently members of the species S. inequiradiata. All are 
poorly preserved, retaining the surface markings in a very imperfect 
manner, but the shells have the general form of this species, and it 
is believed that the identification is correct. The shells are subellipti- 
cal in outline, with the hinge-line equaling the greatest width, and with 
the pedicle valve strongly convex, almost subhemisphereic in form. 
The specimens differ from 8. concava in their smaller size and in the 
absence of the constrictions in front of the cardinal extremities.
