Of this species we have some specimens or fragments, all 

 of the brittle consistens which is earlier noted for this species;

 an irregular massive shape.

Of this interesting species some fragments have been taken, 

 no doubt all belonging to one individual. They are in all re- 

 spects conform to the original specimens, and may have formed 

 a flabelliform or a large cup-shaped specimen; the largest frag- 

 ment which has the upper edge undamaged and thus proves 

 to be a piece of the upper part of the sponge, has a horizontal 

 extent of 100 mm. With regard to the oscula and pores the 

 specimen shows the same structures which are described in 

 the place quoted.
