 VICTORELLA PAVIDA, Kent, Quart. Journ. Micr. Sc. (n. B.\ x. 34, pi. iT. 



Stem repent, very slender and transparent, the clavate 

 enlargements usually wide apart. Zocecia with the 

 upper portion erect, cylindrical, tall, slender, perfectly 

 transparent, below adherent and dilated; branches given 

 off at each side of the expanded base, near the origin 

 of the erect tubular portion of the cell. 



Polypide with 8 long and remarkably flexible tentacles, 

 two of which are everted. 



THIS is an extremely minute species, and has hitherto only 

 been taken in brackish water amongst a prevailingly flu- 

 viatile fauna. Bowerbankia imbricata was obtained in the 

 same locality. 



The zooecial tubes vary in height, but are usually tall, 

 and very slender ; they are generally placed at very con- 

 siderable distances from each other. The stolon widens 

 out at intervals into cell-like expansions, of which the 

 erect tubes are a direct continuation, rising immediately 

 out of them, so that they constitute an integral part of 

 the zooBcium. Just above the cell there is a joint ; and in 

 most cases (but not, I think, universally) there is also 

 one at the point where the expansion narrows into the 

 stem. The ramification is simple and uniform ; on each 

 side of the enlargement, near the base of the erect tube, 

 a single branch is given off, a joint always occurring at 

 the point of origin ; and after a longer or shorter interval 

 the branch, like the main line of the stolon, dilates into 

 a cell. 



The zooecium terminates above in a remarkably tall 



pencil of setae.
