Cretaceous Corals, pt. ii. p. 42 (1870); amended in Quart. 



Journ. Geol. Soc. 1873, p. 558. 



Corallum simple, turbinate, or conical, compressed a little, with 



a broad base, having a mark of former adhesion, or a narrow and 



free base. Epitheca rudimentary or absent. Calice shallow, 



usually elliptical. Septa numerous, solid, often uniting or not. 



Columella absent. Costse well developed. "Wall stout. Septa 



united by synapticula, and sometimes the costse also. 



Distribution. — Fossil. Lower Greensand : England. Eocene: 

 West Indies ; Sind, Asia. 



Subgenus Pal^oseeis, (genus) Duncan, Quart. Journ. Geol. Soc. 

 vol. xxvi. (1870), p. 301, pi. xx. fig. 7. 



Corallum simple, turbinate, and pedicellate. Calice widely 

 open. Septa numerous, crowded, the smaller uniting with the 

 larger, which reach the central fossula. Columella rudimentary. 

 Synapticula numerous. Costse covered by a complete and dense 

 epitheca. 



Distribution. — Fossil. Cainozoic, probably Miocene : Australia. 



The stout epitheca distinguishes this form from Turbinoseris, of 

 which it is a subgenus. 



Genus Phbagmatoseeis, Milaschewitsch, "Xorallen der 

 Nattheimerscliicht.,'''' PalcBOoitographica, xxi. (1878), p. 212. 



Co'rallum simple, adherent, pedunculate, fan-shaped. Calice 

 elongate. Columella absent. Septa numerous, not exsert. 

 Synapticula exist low down in the interseptal loculi ; higher up 

 there are long, oval-outlined granules projecting from the septal 

 lamellse. Wall aporose, and furnished with costse which are con- 

 tinuous with the septa. 



Distribution. — Fossil. Jurassic: Europe. 



This genus is closely aUied to Turbinoseris (if the septa are 

 imperforate).
