46 THE FOSSIL CORALS AND 



The calices are circumscribed, unequal in size, various in shape, and very irregular 

 in their distance. The septa are few in number, alternately large and much smaller ; or 

 they are in sets of fours, one septum being the largest, and the central of the three 

 others is larger than those at its sides. The septa unite much close to the columellary 

 space, and some are thick there. The columella is formed by the union of the septa, 

 and where perfectly preserved is short and lamellar ; but the lamina forming its top is 

 rarely preserved. The septa reaching the axial space may be 12, 16, 18, 21, and 

 rarely more in number. The cost* are alternately large and much smaller, and are 

 separated by distinct and deep spaces with exotheca; they are often very long, are 

 usually wavy in their course, and in some places curve much and enclose a larger 

 or smaller one. They are granular at the sides and edges, in well-preserved parts. 



The base of the coral is thin externally and stout where it probably rested ; and 

 the costse are long, straight, and unequal. Probably this genus will be included in 

 the Fungidse. 



The length of the calices is about yo inch.

The generic and specific characters of this coral, given in the work on ' Les Ani- 

 maux Fossiles de I'lnde,' are seen in some specimens, which unfortunately are rather 

 worn and over-weathered. In addition, it is shown from their consideration that the 

 corallum is large, massive, flat, and not very thick. The series are numerous, not much 

 gyrose, but bifurcating and short. Some calices are limited. The coUines are flat at 

 the top and granular ; the side slopes with the opposite one of the same coUine, form- 

 ing a large angle. The series are not deep ; there is a false columella ; and the septa, 

 alternately large and small, are visible, not very crowded, and about 16 to 20 are 

 found in rather less than half an inch. The synapticulse are few and well marked. 



The corallum is many inches long and about an inch in height. 



Locality. Jhirk, Eanikot group. Survey-number G f4f„.
