Dana's figure and description of the living animal: — "Animal 

 chestnut-brown ; disks long, sinuous and multilobate, bright green." 

 Further, the tentacles are A'erv short, of a darker broMTi colour and 

 apparently in three rows. The corallum agrees with Dana's de- 

 scription so far as it goes, save that no importance can be placed 

 on the septal teetb, and the calices are usually deeper than repre- 

 sented in Dana's section. 



The epitbeca caunot be distinguished. The costae are marked 

 only by spines, which are similar to those of M. cactus, but smaller 

 and more distant. Tlie columella is generally very small in the 

 older and more completely circumscribed calices. It is formed 

 merely by a few trabeculse from the septal edges, and is covered 

 with fine pointed spines. 



Eotuma ; very common with Al. cactus in the same pools near 

 Solkopi.

The remarks made on the specific characters of the genus Mussa 

 apply equally well to this genus, so far as the different modes of 

 growth \\-ill allow.

There are two specimens of this well-characterized species. 

 Septa of four cycles, the fourth incomplete, are present. Fresh 

 calicinal centres are formed on the septa by the deposition of 

 corallum on the floor and walls of the valleys ; the septal edges 

 then break up on further growth. Usually the caUcinal centres
