of this species. The largest is from Norskö, measuring in 
length with the peristome 40 mm, in diameter 15 mm. The 
length of the peristome is very great, 15 mm. All specimens 
have a very rough surface owing to the prominent large 
acerate spicules of the dermis. 
Colour. White, yellowish or grey, when preserved in spirit, 
the peristome silver-coloured. 
Habitat. Norskö, depth 18—25 fathoms (16 Sp.); Mossel Bay, 
depth 3 fathoms (123 Sp.); Duym Point, depth 50 fathoms (254 
Sp.); Greenland, Tessiursak, depth 15—40 fathoms (535 S.).

This species is represented in the collection of sponges, 
dredged up during the Swedish arctic expeditions, by several 
fine and well preserved specimens from Spitzbergen and 
Nova Zembla. All the specimens are furnished with an 
osculum armed with a short ciliary fringe. Only a few spe 
cimens are fringeless. The outer surface of the sponge is 
smooth or slightly hispid. Most specimens are cylindrical, 
about 6: mm in diameter and 25 mm in length. The tarsest 
dredged up at Nova Zembla, is a little compressed, with 
a very great central eloaca and a large ovoid osculum. The 
length of this large specimen is 40 mm, the greatest diameter 
about 20 mm. "The surface of this specimen is smooth. 
The measures of the spicules agree well with those given 
by Heeckel. 
The colour of the dried sponge is cream-white; a little 
darker, when preserved in spirit; the gastral surface, and the 
, S 
portions near the central cloaca are always much darker than 
the superficial parts. 
Habitat. Spitzbergen, Foul Bay, depth 4 fathoms (37 Sp.); 
Mossel Bay, depth 1—2,5 fathoms (75, 153, 200 Sp.); Tromsö, 
Karlsö, depth from 5 to 15 fathoms (Sp.); Matotschkin-Schar, 
depth 4—-6 fathoms (74 N. 5). |
