9(5 THE DEPTHS OF THE SEJ. [chap. in. 



soft mud, as it contained amorphous paste with but 

 a small proportion of fresh shells of GloUgerina 

 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, Bathyhius. 



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 : — 



MoLiiUSCA. — Dentalium, sp. n., of large size. 



JPecten fenestratus, Eorbes, a Mediterranean 



species. 

 Dacrydmnh vitreum, Torell ; Arctic, Norwegian, 



and Mediterranean. 

 Scnobicularia nitida, Muller ; Norwegian, 



British, and Mediterranean. 

 NecBra obesa, Loven ; Arctic and Norwegian. 

 C'B.v&TKC^A.—Anonyx hblbollii, Kroyer (=^. den- 

 ticulatus, Bate), with the secondary appendage 

 of the upper antennae longer and more slender 

 than in shallow-Avater specimens. 

 Ampelisca cequicornis, Bruzelius. 

 Munna, sp. n. 

 One or two Annelides and Gephyrea, which have 

 not yet been determined.
