* This genus I now propose for the reception of Carter's Halichondria infreguens. It is evidently 

 nearly related to Myxiila, and may lie diagnosed as follows: " Esperellinse whose principal megascleres 

 are spined oxea, with which are associated smooth tylota. Microscleres tridentate isochelse and 

 sigmata." 



t Lambe's identification is doubtful.
