Several specimens of this species agree closely with spe- 
cimens from the west-coast of Sweden, described by Fri- 
stedt in »Bidrag: till kännedomen om de vid Sveriges vestra 
kust lefvande Spongize», Kongl. Svenska Vet.-Akad. Handlingar, 
: Bd 21, N:o 6, pag. 50; the rest of the specimens differ a little 
from the Swedish ones in the outer shape, but the spicules 
are of the same size as those of the Swedish specimens, viz. 
0,15—0,18 mm in length. 
Colour. Preserved in spirit, light-, rarely dark-brown; when 
dried a little lighter. 
Habitat. ”Taimur Bay, depth 40 fathoms; Actinia Bay, depth 
d3—10 fathoms; Port Clarence, depth 4—6 fathoms; Konyam 
Bay (Behring Strait), depth 15—16 fathoms (28, 29, 1049, 1058 
V.:); Mossel Bay, depth 15—20 fathoms (79 Sp.). Several spe- 
cimens from all these localities.

This species is represented by several specimens, all dredged 
up during the expedition of the Vega. The sponge is arbuscu- 
lar, pedicelled. Surface even. Oscula terminal or often lateral, 
slightly elevated. The branches are frequently anastomosing, 
a little compressed, the greatest diameter not exceeding 5 mm. 
The length of the largest specimen is about 90 mm, divided 
into three great branches and furnished with numerous slightly 
elevated oscula, placed only on one side. The consistency is 
very fragile. The spicules are, as generally, disposed in nets. 
The fibres are not so well developed as in other Chalin& which
