ules also in the intercostal furrows. The granulations usually are not seen, 

 owing to having been worn slightly. The number ot" costiii and septa is 

 from 32 to 36, the same as in 1'. hdlus.

Shape subconical, enlarging rapidh' in the upper portion of the coral- 

 lum. Cross section elliptical. Costa- correspond to all the cycles of septa, 

 very prominent, those corresponding to the first three cycles fif septa much 

 larger than those corresponding to the fourth cycle. Wall thick; the lower 

 part of the corallum is covered by a calcareous coating. Apparently, when 

 the animal was fully expanded it extended on the outside of the corallum 

 entirely to the base. Septa in four cycles; the first two cycles reach the 

 columella. The fourth cycle fuse by their inner margins to the sides of 

 the third cycle. Their surfaces granulate. Their up})er margins project 

 considerably above the upper margin of the wall, and connect with u})WiU'd 

 extensions of the costae. The septa of the last cycle are dentate (cf 

 PI. IX, fig. 2c). One septum of the second cycle, which has its margin intact, is 

 dentate, while another of the same cycle has ;in entire margin. The septal 

 margins are, in all cases where preserved, except one, dentate or creuate. 

 Pali, with granular surfaces, before the septa of the third cycle. Columella 

 made up of twisted pieces. Calice not very deep. Greater transverse 

 diameter of calice, 16 nun.; lesser transverse diameter of calice, 13 nun.; 

 height of corallum, 22.5 nun.
