of Stereoplasma or other filling. The columella composed of several 

 flattened pillars. 



Sehr nahe verwandt mit Duncania, aber mit dünnerem Epi- 

 thek. Die Septa sind deutlich nach dem 6 strahligen System ge- 

 ordnet. 



Oculinidae. 



Neohelia. Corallum with a very abundant and diffuse coe- 

 nenchym enerusting the stems of Gorgonoids, with very short 

 branches only. Calicles with the septa arranged in five Systems, 

 which are often fused together by the coenenchym: gemmation irre- 

 gularly dichotomous. Fife Systems and four cycles of septa; a deep 

 fossa; no columella. 



BatheUa. Corallum arborescent, massive; calicles disposed 

 alternately in nearly straight rows on either sides of the several 

 branches with very prominent margins. Coenenchym white, compact, 

 and dense, with its surface covered entirely by curved Striae 

 continuous with the costae. Calicles deep and widely open. with four 

 cycles of septa, and a single crown of pali. Columella large, composed 

 of numerous trabeculae. 



Splie^iophyllia. Corallum solitary, free, pedicellate, compressed, 

 with septa finely denticulate at the summits and numerous sharpedged 

 costae which are denticulate, rendering the corallum exceedingly 

 rough. A scanty epitheca at the base; no endotheca or exotheca; 

 a well developed lamellar columella. 



Fungidae. 



Bathyactis. Corallum free, discoid, not attached or cup-sha- 

 ped in the youug condition, thin and fragile; primary septa free, 

 the others united so as to form six deltoid combinations ; upper 

 margins of the septa usually coalescent over the apices of the 

 deltas. Septa deeply toothed; synapticulae sometimes abundant, 

 sometimes few, arranged in a series of concentric circles. Columella 

 well developped. 



Für Fungia symmetrica Pourt. 



Eupsmnmidae. 



Leptopeniis. Corallum discoid, excessively thin and fragile, 

 with the wall so completely covered by perforations as to ressemble 

 a lace work, beig built up of a network of delicate radiating and 

 circumferentially - directed trabeculae. Perforations placed at 

 regulär intervals between the costae, and each divided into two by 

 the septa which alternate with the costae. Septa, except the 

 primaries, which are free, coalescing successively according to 

 Order, and forming deltoid figures, beset with a series of long
