This is a very neat species, and when fully expanded, the star of 

 tentacles is over a fourth of an inch in diameter. The tentacles are 

 peculiar in having, instead of a fringe of oblong papilla3, a few scat- 

 tered verruciform prominences. The stolon uniting the polyps was 

 not observed, and I am not satisfied that the polyps were not solitary, 

 as was my impression when the drawings were made.
