Dr. F. Briiggemann on Stony Corals. 307 



Savlgny's figure was either mistaken or overlooked by 

 subsequent authors. Audouin (Explic. somra. d. Plancli. 

 Savign, p. 233) declares it to represent a Caryo-phyllia^ per- 

 haps the young of G. carduus. Ehrenberg (Corall. Roth. 

 Meer. p. 92) refers to it under his CaryopliylUa lacercij re- 

 marking that he himself had not found this coral in the E,ed 

 Sea. M.-Edwards and Haime have not mentioned it any- 

 where*. 



III. Antillia. 



Antillia, Duncan, Quart. Journ. Geol. Soc. xx. p. 28. 



Coral short, turbinate, in the earliest stages fixed to the 

 ground by a short pedicel, afterwards free, pointed at its base. 

 Epithecawell developed, moderately appressed, generally with 

 transverse ringlets of growth. Costaa prominent, equal, den- 

 ticulate. Calicle more or less oblong, with a longer and a 

 shorter axis. Septa much projecting, rounded at their sum- 

 mits, with their free inner edges uniformly and minutely 

 serrato-dentate ; the inner thirds of the larger septa sometimes 

 separated by an emargination as paliform lobes. Columella 

 large, oblong, spongious. Animal with a single row of nume- 

 rous, small, verruciform tentacles, an even, more or less gra- 

 nulate disk, and a single, oval or linear mouth. 



This genus was originally established on some fossil West- 

 Indian coi'als differing from Montlivaltia in the possession of 

 a well-developed columella. It has become necessary to draw 

 up a more precise definition of the genus in order to differen- 

 tiate it sufficiently from its recent allies. It proves to be 

 widely distributed in the coral seas ; there are at least four 

 living species belonging to it.
