loped, projecting, spoBgy. Septa moderately developed, very 

 thin, not exsert, finely and unequally dentate, those of tlie last 

 cycle less develoj)ed than those of the penultimate. Endotheca 

 scarce. Epitheca surrounding tlie corallites thin and compact. 

 Distribution. — Mecent. Mediterranean.

 des Corall. vol. iii. p. 123 (1860). 



Colony dendroid and very short and dichiotomous, short brandies 

 directed outwards. Calices witli irregular-shaped margins, in- 

 creasing by fissiparity. Four cycles of septa well developed, and 

 some of the fifth ; higher orders bending to and joining the penul- 

 timates. Columella spongy. Costge delicate, with indistinct 

 granules. 



Distribution. — Fossil. Oligocene : Europe.

Corallum simple or colonial, free or attached, with lateral 

 buds, cylindro-conical or compressed. Calice elliptical, rather 

 deep. Columella more or less projecting, composed of convoluted 

 " leaflets." Septa narrow, sharp at the edge, hardly exsert ; first 

 and second cycles extending to the columella, unequal ; succeed- 

 ing cycles joined with those o£ preceding cycle. Costge simple, 

 distinct from the base, close, subequal, granular. Epitheca 

 absent or rudimentary. 



Distribution. — Becent. Philippines. 



Several species of this interesting genus are described by 

 Semper and beautifully figured. The budding is below the cali- 

 cular margin, and some buds may bud again. The parent is 

 clearly alive after this process, and the whole colony is a pale 

 pink in colour when alive, and the tentacles, which are long, 

 are of a deeper tint. Some coralla are attached, others are free j 

 and some have buds, others have not. In one instance there is a 

 bud with a quadrangular transverse outline springing from the 

 calicular margin.
