28. Balanophjllia (Thecopsammia) jistula n. sp. 



Corallum greatly elongate, vernriforrn, subcylindrical and of 

 nearly equal diameter tbroughout, covered with a thin epitbeca 

 beneath which it is grauular and very indistinctly costate. 



Calicular orifice broadly elliptical, with the lip thickened. Septa 

 not exsert, in six systems and four complete cycles, thick and 

 spongy at the junction with the calicular margin, thin and finely 

 granular or spicular elsewhere. Those of the first cycle are much 

 the largest; those of the second cycle are large, but do not quite 

 reach the columella; those of the fourth cycle are a good deal 

 larger than those of the third, towards which they curve and in 

 front of which they meet. 



Columella elliptical, prominent, loosely spongy, fairly deep-seated. 



Length of broken corallum 95 millim. 



Major diameter of calicle 7 » 



Minor » » » 6 » 



What look like secondary corallites, produced by budding, may 

 be present on the dead part of the corallum, far frorn the calicle; 

 but they are separate individuals which have simply settled there, 

 as is shown by the fact that when they are detached the wall 

 of the original corallum is found intact. 



29. Endopachys Weberi n. sp. 



Corallum strongly compressed, pedicellate, the lateral costge 

 form the usual wings which, however, do not invade the pedicle. 

 The outer surface of the corallum is crisply granular, the granules 

 forming costate rows on the thecal wall, but not on the pedicle 

 to which they give a finely shaggy appearance. 



Calicle narrowly elliptical, the fossa very deep. Septa spongy 

 and granular, in six systems and four cycles. Those of the first 

 two cycles are much the largest and most exsert: those of the 

 fourth cycle are small and unite with those of the third high up
