ZOOPHYTES. 



P. foliaceous, cespitose ; folia thin, broad and broadly crispate, some- 

 times lacerate and proliferously extended. Corallum with the ori- 

 rimes remote, large ; lamellae thin and delicate, not crowded, denti- 

 culate; under surface striate. 



East Indies. Esper. 



This coral, commonly called elephant's ear, forms clumps of spread- 

 ing and erect leaves, crispately curving, having a finely lamello-striate 

 surface, and distant scattered oririmes. The lamellae are very narrow 

 and even, and rather distant. Esper states that the leaves are thin, 

 and even diaphanous. They frequently coalesce by their back sur- 

 faces, and thus become bifacial folia. The species is near the Trida- 

 cophylliae in habit.

sp. 1 ; Ehrenberg refers with a query to 

 Esper's figure, and gives the following 

 description : "Quadripollicaris, stellarum 

 difHuentium labiis in frondes bipollicares, 

 crispas et amplas, late venosas, laceras, 

 proliferasque productis, stellarum centro 

 tumidulo, fere 6'" lato." Folia some- 

 times bifacial. Ehrenberg suggests that 

 if distinct, the species may be named, 

 megastoma.

5. PAVONIA CACTUS. (Ehrenberg.) 



P. erecta, Jobata, bifrons, lobis foliaceis, crispis, margine rotundatis, 

 crenulatis, scepe excisis ; polypis virentibus, tentaculis obsoletis. Co- 

 rallum oririmis semilinearibus, seriebus sulco levi conjunctis, subcon- 

 centricis, cottibus non omnino obsoletis ; lameUis subtilibus, arenoso- 

 asperis, obsolete denticulatis. 



Erect and lobed, lobes foliaceous, crispate, with the margin rounded, 

 crenulate, often excised ; polyps green, tentacles obsolete. Coral- 

 lum with the oririmes half a line broad, series united by a slight 

 trench, subconcentric, separated by ridges not quite obsolete ; 

 lamella? minute, arenoso-asperate, obsoletely denticulate.
