" This beautiful coralline 

 is one of the smallest we 

 meet with. It rises from 

 tubidi, growing upon Fu- 

 cus's ; and passes from thence 

 into sickle-shaped branches, 

 consisting of single rows of 

 cells, looking, when magni- 

 fied, like bull's horns in- 

 verted, each one arising out 

 of the top of the other. The upper branches take their rise from 

 the fore part of the entrance of a cell, where we may observe a stiff 

 short hair, which seems to be the beginning of a branch. The 

 opening of each cell, which is in the front of its upper part, is sur- 

 rounded by a thin circular rim ; and the substance of the cells 

 appears to consist of a fine transparent shell, or coral-like substance," 

 Ellis. — It is impossible to improve this description. I have only to 

 add that there are no granules in the walls of the cells, as in 

 Crisiae.
