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, vellowish 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 Z em b la. All the specimens are furnished with an
osculum armed with a short ciliary fringe. Only a few
specimens 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 largest,
dredged up at Nova Zembla, is a little compressed, with
a very great central cloaca 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 Hfeckel.
The colour of the dried sponge is cream-white; a little
darker, when preserved in spirit; the gastral surface, and the
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. S.).
