Family CLIONID^. 



Animal fusiform. Head with a series of conical prominences on 

 each side. Wings two, witli a central foot-like aj)pendage between 

 them.

 ular arms in a rudimentary condition ; there are two genera, one, Cli- 

 one, with the head indistinct and the tentacles defined, and the other, 

 Cliodita, with the head distinct, and the tentacles not apparent.
