' There can be no doubt tliat Lizzia Kollikeri 

 (legeiih. is identical with Melicerta fasciculata, Per. 

 and LeS. The description agrees fully, and the 

 origin is the same. Is not Lizzia dibalia Buscli 

 also a Kollikeria or a Rathkia? 



- This family differs from the Bougainvillidie, 

 by the peculiar prolongation of the genital appa- 

 ratus of the free Medusa, which extends from the 

 VOL. IV. 44 



proboscis to the radiating tubes, along which it 

 projects, like curtains, into the cavity of the bell. 

 ' I see no reason why the Willsiadffi of Forbes 

 should be separated from the Berenicida; of Esch- 

 scholtz, founded upon the species drawn by Le- 

 Sueur, and described by Peron and LeSueur. The 

 genus Eudora is evidently drawn from imperfect 

 Acalephs.
