The unequal tentacles and the almost globular projecting mouth, 

 6-cleft within, are striking characters of this species. The general 

 colour of the body is a bright lake, with paler vertical lines ; the ten- 

 tacles have a reddish ochre tint, becoming bluish at base ; and the 

 disk, which is of a bright lake, is strongly marked with lines running 

 from the base of the tentacles to the rnouth prominence. The mouth 

 is of a bright rose-red colour, deeper within. When expanded, the 

 species presents a flat disk, having the appearance of a beautiful 

 aster. J. P. COUTHOUY.
