Genus PORITES, LamarcTc. 

 1. PoRiTES Gajbnsis, Buncan. Plate XXII, Figs. 6, 7. 



The corallum is massive, has a broad base, and an irregular cylindrical stem ending 

 in several gibbous pinnacles which are rounded at the top. Layers of growth are on 

 the corallum, which is covered with minute calices well separated by a porous ccenen- 

 chyma. The septa are 12 in number; the pali are very small, and the columella also. 



Height of the corallum nearly 3 inches ; breadth 2 inches. 



There are five calices and intermediate structure in -^o inch.
