soft mud, as it contained amorphous paste with but 
a small proportion of fresh shells of Globigerina 
and Orbulina. There was an appreciable quantity 
of diffused amorphous organic matter, which we 
were inclined to regard as connected, whether as 
processes, or ‘mycelium, or germs, with the various 
shelled and shell-less Protozoa, mixed very likely 
with the apparently universally distributed moner 
of deep water, Bathybius. 
On careful sifting, the ooze was found to contain 
fresh examples of each of the Invertebrate sub-king- 
doms. When examined at daylight on the morning 
of the 23rd none of these were actually living, but 
their soft parts were perfectly fresh, and there was 
ample evidence of their having been living when 
they entered the dredge. The most remarkable 
species were :— 
Mouiusca.— Dentalium, sp. n., of large size. 
Pecten fenestratus, Forspes, a Mediterranean 
species. 
Dacrydium vitreum, ToRELL; Arctic, Norwegian, 
and Mediterranean. 
Scrobicularia nitida, Miter; Norwegian, 
British, and Mediterranean. 
Neera obesa, Lovin; Arctic and Norwegian. 
CrustacEaA.—Anonyx hélbollu, KROYER (= A. den- 
ticulatus, BATE), with the secondary appendage 
of the upper antennze longer and more slender 
than in shallow-water specimens. 
Ampelisca equicornis, BRUZELIUS. 
Munna, sp. un. 
One or two ANNELIDES and GEPHYREA, which have 
not yet been determined.
