Fig. 66. A group composed of most of the foregoing species, and in- 
cluding E’schara, Flastra, &c. A small Cidaris and a portion of a 
Belemnite are also attached to this specimen. 
Retipora, resembling R. celluldsa, covers a part of fig. 61. 4, and jig. 64. 5. 
The slabs to which these zoophytes are attached often resemble parts of a 
recent coral reef.
