that they do not belong to the Sponge. So many Sponges accapa-

Description. 
Carter described in 1874 a new Sponge, which he named Zsperia 
cupressiformis '); in 1874 he described a Sponge which was accor- 
ding to him a variety of this species; in my paper on the Desma- 
cidinae 1 have made a new species out of it, because it seemed to 
me that both Sponges are very well distinguished from one another. 
E. cupressiformis has „bows’” and „forcipiform’” spicules; #%. biha- 
matifera is without these. 
The specimen from the Barents-Sea is a true Cladorhiza, ha- 
ving a long, slender main stem, with very small secundary twigs. 
The speeimen, not being complete, I have not illustrated it. The 
stem is about 15 cm. long, but measures only 3 mm. in diameter; 
the colour is yellowish-white (in spirit).
