ISO TEE DEPTHS OF THE SEA. [chap. iv. 



in 567 fathoms. Mr. Jeffreys reports the contents of 

 the dredge as small but very interesting. Among 

 the mollusca he notes Terebratula septata, Limopsis 

 borealis, Hela tenella, Verticordia abyssicola, Turbo 

 filosus, and Ringicula ventricosa. Turbo Jilosus and 

 its variety T glabratus had previously been known 

 only as fossils in the tertiaries of Calabria and Mes- 

 sina. Terebratula septate, Limopsis borealis, and 

 Hela tenella are likewise fossil in the Pliocene beds of 

 southern Italv, and are found living in the Scandi- 

 navian seas. Mr. Norman notes among the crus- 

 taceans new species of Ampelisca and of six other 

 genera; and the beautiful scarlet Echinus microstoma 

 was the most conspicuous echinoderm. 



The wind, as the vessel passed over the slope of the 

 Channel, was rather too light for successful dredging; 

 the drift- way was scarcely sufficient to carry the 

 dredge along. The tangles were most valuable, 

 coming in as highly effective aids, particularly in 

 securing all things provided with anything in the 

 form of spines or other asperities. 



On the 8th the first haul was nearly a failure. Other 

 hauls later in the day, at 690 and .">()() fathoms, gave 

 important results. Rhynchonella sicula, Seguenza ; 

 JPleuronectia, sp. n. ; and Actceon, sp. n., occurred: 

 besides the usual northern species. Mr. Norman 

 reports as to No. 3: "A most important dredging, 

 the results among the Crustacea being more valu- 

 able than all the rest put together- — at any rate 

 of the first cruise. It contains almost all of the 

 choicest of the new species in last year's cxpedi- 

 tion, and four stalk-eyed crustaceans of great in- 

 terest, three of which are new, and the fourth,
