(3) the verrnicular striae of the corallites and coenenchyma, 

 though bold euough, are not so coarse as in D. profunda; 



(4) the mouths of the calicles are larger, owing to the lip 

 being less swollen: 



(5) the septa of the 3 rd cycle are more nearly equal to those 

 of the other two cycles, and they almost always unite with the 

 secondaries ; 



(6) the tissue forining the columella is more abundant. 



33. Dendrophyllia (Coenopsammia) 



This is another species that at first sight simulates an Amphihelia, 

 having a strong resemblance to A. tenuis Moseley. 



Colony made up of corallites which bud laterally near the 

 calicular margin in au alternate-distichous (occasionally dichotomous) 

 arrangement, without coenenchyma. 



The surface of the corallum is frosted with sharp little granules, 

 but there is no striation or verniiculation. 



The corallites are elongate and funnel-shaped, with very deep 

 empty-looking calicles, the mouths of which are a little oblique. 



Septa subequal, in six systems and three cycles, those of the 

 third cycle uniting with those of the second : they are not exsert 

 and are very shallow, projecting but little into the calicular fossa. 



There is no columella. 



Length of a corallite about 6 millim. 



Diameter at base » 2 » 



Diameter of calicular orifice about 3 » 



34. Endopsammia poculum n. sp. 



Corallum elongate, slightly curved, not compressed, gradually 

 expaading from a distinct pedicle with an encrusting base, tra- 

 versed from calicle to base by sharply-granular slightly-sinuous 

 costae of equal size. Calicle circular, calicular fossa very deep. 



Septa thin, imperforate, exsert, in six systems and four cycles 

 of which the last is incomplete. The septa of the first cycle are
