One large globular specimen, with two thirds of its surface 
covered by a compact coenenchyma. The corallites are not 
more than 2 millim. in diameter, and they thus correspond 
rather with this species than with R. calycularis : Lamk., sp., 
in which, according to Ed. & H., they are from 3 to 4 
millim. in width. The description of the species given by 
Ed. & H. is very meagre. 
From the Tizard Bank, Itu-Aba, depth 2 fath. 
The specimen is in one place incrusted by Heliopora 
ccerulea .

The specimen doubtfully referred to this species is ramose ; 
the branches about 10 millim. thick, uneven, nodose, fur- 
cating, their lower portions completely enveloped by wrinkled 
compact coenenchyma; the calices oblique, about 4 millim. 
wide.
