The above three species do not strictly belong to this genus, 

 but I have placed them here provisionally until better specimens 

 and more information be obtained respecting them.

My only specimen is not in good preservation. 



Filicella, n. g. {filum, a thread, and cella). 



Gen. Char. Cells filiform, distinct, adnate, united at the extremi- 

 ties ; dichotomous aperture subterminal, not projecting. 



1. Filicella anguinea, n. s. 



Ramsholt. | j 



Repent, snake-like, elongated, subcylindrical, or rather club-shaped, 

 tubulous, glossy, united at the extremities, adnate, dichotomous; 

 aperture oval, rather depressed, subterminal. 



I propose tEis genus for the reception of a very minute zoo- 

 phyte from the coralline crag which much resembles Alecto, but 

 differs in being more elongated, less cylindrical, and with its pe- 

 ritreme even with the cell ; it does not adhere by an expanded 

 side like Alecto, but is filiform throughout, the cells are more di- 

 stinctly separated, and are but slightly attached (laterally) to the 

 surface of the interior of an Echinus. The cell is compact, 

 smooth, not porous. This is the smallest zoophyte I am acquainted 

 with, being scarcely visible to the naked eye.
