Allman says of the genus, " we are almost tempted to 

 regard it as an abnormal condition of some other form." 

 It must hold a provisional place until some new light is 

 thrown upon its history by further observation.

GENERIC CHARACTER. Stem simple or branched, rooted 

 by a creeping filiform stolon, the whole sheathed in a thin 

 chitinous tube, smooth or annul at ed ; polypites terminal, 

 clavate ; tentacles capitate, scattered over the body or in 

 several whorls ; reproduction by means of fixed sporosacs, 

 borne on the body of the polypite. 



AMONGST the polypites which answer to Gaertner's de- 

 scription, two or three very distinct modes of reproduction 

 are met with, and it is therefore necessary to distribute 

 them into corresponding groups. His name is here em- 

 ployed in a restricted sense, to designate the species that 

 do not originate free medusiform zooids. The differences
