9(5 THE DEPTHS OF THE SEA. [CHAP. in. 



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, 5 or germs, with the various 

 shelled and shell-less Protozoa, mixed very likely 

 with the apparently universally distributed moner 

 of deep water, Bathybws. 



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 : 



MOLLTJSCA. Dentalium, sp. n., of large size. 



Pecten fenestratus, PORBES, a Mediterranean 



species. 

 Dacrydium vitreum, TORELL ; Arctic, Norwegi; 



and Mediterranean. 

 Scrobicularia nitida, MULLER ; Norwegiai 



British, and Mediterranean. 



Necera obesa, LOVEN ; Arctic and Norwegian. 



CRUSTACEA. Anonyx hdlbollii, KROYER (=A. den- 



ticulatus, BATE), with the secondary appenda^ 



of the upper antennas longer and more slend( 



than in shallow-water specimens. 



Ampelisca aquicornis, BRUZELIUS. 



Munna, sp. n. 



One or two ANNELIDES and GEPHYREA, which hav< 



not yet been determined.
