Skeleton. The skeleton consists of only acerate spicules. 
The acerate spicules (Plate 23, fig. 18). The length of these 
spicules is 0,17 mm; they are slightly curved or straight, com-

This species differs from the other species which I have seen. 
It is blade-shaped, the margins more or less broken. Only two 
specimens were obtained, both probably fragments of only one. 
'The larger of the two is about 60 mm in length, 30 mm in 
breadth, the thickness being only 5 mm. The surface is 
smooth, furnished with a few larger oscula. The consistency 
is exceedingly soft and fragile. 
Skeleton consists of only acerate spicules, disposed 
in nets. 
The acerate spicules (Plate 23, fig. 19) are slightly curved, 
short-pointed and 0,2 mm in length. 
Colour. Tight with a tint of yellow, when preserved in 
spirit. 
Habitat. East-coast of Greenland, depth 140 fathoms (581 5.). 
With regard to the species Chalina Grant, Remiera Nardo 
and Amorphina OO. S., I have been very doubtful whether 
I should indicate only the genus or both the genus and 
the species, as I now have done. I have not been able to 
identiy more than a few of them wit forms, previously 
known; the greater part, however, I have described as new, 
though one or several of them may have been described before.
