Plaäte 24HonD Oo 
There was dredged up only one specimen of this sponge. 
It incrusts a bryozoon, forming one piece, the length being 25 
mm, the breadth 15 mm, and the thickness not exceeding 15 mm. 
The surface is slightly rough. Oscula minute, dispersed. The 
consistency fragile. The spicules are not numerous, and they 
are situated, the great without order, the small fasciculated. 
Dermal membrane pellucid. 
Skeleton. The skeleton consists of acuate spicules of 
two distinct kinds. 
The acuate spicules (Plate 24, fig. 5, 6). The larger of these 
spicules are 0,6 mm in length, slightly curved at the base and 
sharp-pointed at the other termination. These spicules are 
dispersed in the tissues without order. 
The smaller, hair-fine acuate spicules are arcuated in the 
same manner as the larger, but they are exceedingly fine, a 
little shorter and contrary to the others, fasciculated. They 
are about as numerous as the larger ones.

Amorphina nodosa n. sp. 
Plate 24, fig. 7, 8. 
This Amorphina is the largest of all the species described 
in this volume. It is represented by only one specimen from 
the arctic expeditions of Prof. Nordenskiöld. 
This species is elongated, the length being about 100 mm, 
the thickness and the breadth 50 mm. TI have seen another 
specimen from Greenland, which is much larger, almost 
spherical and of the size of a head. Surface, inner structure 
and spicules are the same in both specimens. The surface is 
rough, furnished with numerous, 1—5 mm long papille, and
