Geu. n. Blastulatrochus e Farn. Turbinol. The corallum is 

 Compound, is fixed by a broadish base, and is conico-cylindrical in 

 shape. The wall is thik; and there is a well marked epitheca, the 

 costae being rarely visible. The calice is very deep, and there is 

 a rudimentary columella. The septa are stout. Budding takes place 

 from the wall high up; and the buds adscent and frequently Joint 

 by their walls to others of different corallites, so as to constitute 

 a bush-shaped corallura. 



Gen. n. Blastosmilia e Farn. Astraeid. The corallum is 

 Compound; and there ar repeated geramations from the wall of the 

 parent corallite, and occasionally from the walls of buds. The 

 corallites are conico-cylindrical, long, bent, except the parent; and 

 the calice is circular in outline and deep. The wall is thin and 

 is covered with a granulär epitheca, the rudimentary costae being 

 only visible close to the calices. The columella is rudimentary, but 

 exists as trabecnlae from the septal ends. The septa are very thin, 

 slightly exsert, not incised, project but little into the calicle and 

 the primaries and sometimes the secondaries unite at the base of 

 the fossa with the small deeply seated columella. There are six 

 Systems of septa; and the fourth cycle is usually incomplete in some 

 Systems. The dissepiments are wide apert and are formed at the 

 buttom of the calicle by the septal ends becoming oblique and wide 

 and occluding the space below.
