Height of corallum 3J inches ; breadth 1 inch. 



There are about six corallites and intermediate structure to the length of 1 inch. 



Locality. South-east of Bill, Gaj series. Survey-number G ^^.

3. Hbliaste^a anomala, Duncan. Plate XXI, Fig. 10. 



The corallum is very short, covers a wide extent of surface, is nearly flat above, and, 

 although pedunculate, has almost a flat base covered with radiating longitudinal folds 

 of epitheca. 



The calices project but slightly, are irregular in shape and separate, and costae pass 

 down into the intercorallite spaces. The calices are shallow, oblique, circular, or deformed 

 or elliptical ; and the columella is very small. The septa at the margin are very thick, and 

 within the fossa are distinct, narrow, as a rule wide apart, unequal, and in four cycles ; 

 usually some of the primaries are very distinct and long. Dissepiments are rare. The 

 corallum is many inches long and about 1 inch thick. 



The diameter of the calice is from t^ to -j^ inch.

1. Bkachtphtllia Indica, Duncan. Plate XXI, Fig. 2. 



The corallum is massive, convex above, circular in outline, and flat below. The 

 coraUites are large, united by exotheca, and the costse of neighbouring calices often 

 unite. The calices are circular, oval, elliptical, and irregular in outline, shallow and 

 crowded with septa, which pass so far upwards that there is barely a columella. The 

 septa are in five cycles in six systems in the largest calices, and are alternately large and 

 very small ; and this is the case with the costae also. The exotheca is well developed. 

 The distances of the calices differ ; some are wide apart and others are crowded. 



Height of corallum 2 inches ; breadth 7 inches. 



Length of calices f to 1 inch.
