 — F5. — The perfect 

 '^\ form of this fossil is not 

 known. Its delicate 

 and beautiful expan- 

 sion often extends over 

 several inches, its fork- 

 ing and slightly diverg- 

 ing branches united by 

 slender filaments. No 

 pores and nothing but 

 a thin film of coaly mat- 

 ter. (Hall).

 agara formation (in 

 the shale). Vh. — In 

 general appearances 

 it closely resembles 

 Oorgania assimilis of 

 England (Sil. Re- 

 search, pL 15, f. 27) ; 

 but it has no solid axis 

 the coral growing out 

 in all directions from 

 a central point, as a 

 wrinkled and flat- 

 tened network of 

 branches, indistinctly 

 striated, but with no pores visible. (Hall). Vh.
