Balanophtllia, Searles Wood, Duncan. 



13. Balanophyllia scabra, n. sp. PL V, figs. 7. 7a. 



Corallum simple, large, stoutly pedunculate, and gradually expand- 

 ing, •with a slight curve, into an elliptical calice. 



The costse, which are distinct from the base, are equal in size, uni- 

 form, and closely and conspicuously dentate. 



The elliptical calice is deep. 



The septa, which are crowded and very thin, are in five cycles, of 

 which the last is not complete. Those of the first and second cycles are 

 of equal predominant size and are slightly exsert. The quaternaries, 

 especially those immediately adjoining the large septa of the first and 

 second cycles, are larger than the ternaries, and unite with them not far 

 from the columella. In those quarter-systems in which a fifth cycle of 

 septa is developed these unite with the septa of the fourth cycle not far 

 below the calicular margin, and the quinary nearest the large septa of 

 the first and second cycles becomes the largest of the united triad. The 

 edges of all the septa except those of the two first cycles are either 

 ragged or cut into deep serrations, the teeth nearest the columella 

 standing upwards like pali. 



The columella is well-developed, spongy, and either plane or 

 concave. 



In the type specimen the greatest height of the corallum is 26 

 mm., the major diameter of the calicle 21 mm., and the minor diameter 

 15 mm. 



Dredged by Professor Wood-Mason in the Andaman Sea.

14. Eupsammia regalis, n. sp. PI. V, figs. 8., 8a. 



Corallum simple, free with traces of former adhesion, curved, cor- 

 nute, compressed. 



Costa? distinct in the upper two-thirds of the corallum, occasionally 

 trifurcating, united at regular intervals across the deepish intercostal 

 incisions by horizontal spicules. 



Calice elliptical with the major marginal axis on a slightly lower 

 plane than the minor, deep, open. 



The septa are in five cycles, of which the last is not complete, and 

 are exsert. Those of the first two cycles are of equally predominant 

 size and stoutness, while those of the other cycles are smaller and 

 diminish in size in order, except that in the quarter-systems in which 

 a fifth cycle is developed the quinary septum immediately adjoining the 

 primary is larger than its neighbour of the fourth cycle.
