septa of the first two cycles, and where the quateruaries uuite 

 in front of the tertiaries a very prominent paliforra lobe occurs. 

 The columella is elongate, spongy, and rather deep-seated.

This species resembles H. rotundata in the conspicuous paliform 

 projections of the septa of the fourth cycle, but differs in having 

 more septa and in the fact that in every systern the septa of the 

 4 th cycle unite in front of those of the second cycle. 



31. Dendrophyllia fiorulenta n. sp. 



Colony made up of corallites which bud laterally, near the ca- 

 licular margin, in an alternate-distichous arrangement, without 

 coenenchyma. 



The corallites are turbinate, the mouth being slightly compressed 

 with the major diameter on a slightly lower plane than the 

 minor: the outer surface of the thecal wall is scabrous, and ver- 

 miculate longitudinally. The septa, which are in six systems and 

 four complete cycles, are decidedly exsert, those of the first two 

 cycles being the most so and carrying with them those of the 

 fourth cycle. The primary septa are free, and the secondaries are 

 usually free, though occasionally the tertiaries unite with each 

 other over the secondaries at the columella. The septa of the 

 fourth cycle unite with the tertiaries high up on the calicular 

 wall. Though the septa of the first two cycles are the largest 

 and most spongy they do not encroach very much on the cali- 

 cular fossa. 



The columella is deep-seated, reticulate and rather small. 

 Length of a corallite about 10 millim.
