outline, widely open, and the fossa is shallow. The base is small, circular, and blunt. 

 There are four cycles of septa in six systems, and there is not much difference in the 

 size of the first and second orders, which are the longest and largest ; the tertiaries are 

 smaller and not so long, and the highest orders are linear and short ; they are all linear 

 within, granular, not exsert, and correspond to costse larger than their bases, especially as 

 regards the higher orders. Pali exist before the tertiary septa; they are distant from the 

 septa, and small. The columella is small, and its tissue very lax and wide apart. The 

 costse are subequal, distinct to the base, granular at the edge and sides, the epitheca 

 being rudimentary there. Near the base the costse of the higher orders are the smallest.

The corallum is tall, slender, not quite straight, marked with growth-rings, and the 

 calice is circular in outline. The base has a small scar. The costse are alternately large 

 and small below, less unequal above, wavy, distinct, multigranular above, and .some are 

 small and moniliform near the base. The calice is small, and the columella exces- 

 sively so. The pali are small and few in number, and are before the third septa 

 when the system is complete. The septa are unequal, the primaries large, and the 

 higher orders much smaller than their costse. The septa are long and distant, and 

 there are four incomplete cycles of them.
