slightly attenuated. The spicules agree well with those figured
by Carter op. cit. The spined acuate are 0,2—0,3 mm in length,
the obtuse spicules 0,25 mm. The anchorate spicules differ a
little from those described by Carter. In our specimen there
are two kinds of anchorate spicules, the larger perfectly agreeing
with those figured by Carter, they are 0,05 mm in length; the
spicules of the other kind are only 0,02 mm in length, but in
shape they are quite like the larger ones. The sponge is
cream-coloured.
Habitat. East-Greenland, depth 130 fathoms (580 S.).
Genus Melonanchora Carter.
MeSonanchora elliptica Carter.
Plate 25, fig. 5—55.
Melonanchora elliptica, Carter, Ann. Mag. Nat. Hist., Ser. 4, Voi. 14, pag.
212, Plate 13. fig. 6—12, and Plate 15, fig. 35 a, b;
Deep-sea sponges from the Atl. Ocean.
The consistency, the form and the colour agree totally with
those of Melonanchora elliptica Carter. The surface is furnished
with tubercles, and the dermal layer is easily separated from
the other soft sponge-body. Our specimens were growing freely.
All our specimens are fragments.
Skeleton. The skeleton consists of obtuse spicules, of
melonanchors, of equianchorate spicules.
Tlie obtuse spicules (Plate 25, fig. 51) are smooth, slightly
curved or straight. The ends are sometimes slightly infiated.
Their length is 0,os mm.
The melonanchorate spicules (Plate 25, fig. 52) are very numerous,
their length being 0,07 mm.
The equianchorate spicules (Plate 25, fig. 53—55) are of two
kinds, the larger 0,o6 mm in length, the length of the smaller
being only 0,oi5 mm.
Colour. Grey, when preserved in spirit.
Halitat. East-coast of Greenland, depth 130 fathoms (580 S.).
