tinually being discovered there, and have never been published. — Besides 

 the Mollusca in this dredging from 994 fathoms, Professor Duncan in- 

 forms us that there are two new genera of Corals, and Flabellum distinctum, 

 which last he regards as identical with one from North Japan. It coincides 

 with the discovery on the Lusitanian coasts of two Japanese species of a 

 curious genus of Mollusca (Pecchiolia or Verticordia), both of which are 

 fossil in Sicily, and one of them in the Coralline Crag of Suffolk. Pro- 

 fessor Wyville Thomson notices undescribed Sponges from the same dredg- 

 ing. The weather was very hot, and the sea quite smooth, at 10 p.m. 



15. Thursday, July 21st. On deck at 5 a.m. Dredged all day in 

 from 600 to 1095 fathoms (Stations 17, 17 a) with extraordinary success. 

 Together with many of the new and peculiar species of Mollusca ob- 

 tained at Station 16 (994 fathoms), some of which were here alive, 

 occurred — Nucula delphinodonta, Leda (Yoldia) sp. n., L. abyssicola, 

 Axinus eumyarius, Siphonodentalium vitreum (the first being North- 

 American and Norwegian, and the last three Arctic and Norwegian), S. 

 coarctatum (a well-known Subapennine fossil), Dischides sp. n., Chiton 

 albus (northern), Molleria costulata (Arctic), Trochus reticulatus (a Cala- 

 brian fossil), Omphalitis monocingulatus, Seg. MS. (a Sicilian fossil), Hela 

 sp. n., Eulima sp. n., Scalaria frondosa (a Leghorn and Crag fossil), and 

 Trachysma delicatum (a Sicilian fossil). Of Crustacea, there were Apseudes 

 spinosa (Norwegian and British), A. grossimanus (sp.n.), and Paranthura 

 elongata (sp. n.). Of Polyzoa, Gellepora abyssicola, sp. n. (Busk, MS.). Of 

 Corals, Ccenocyathus sp. n., and an undescribed species of an unknown genus 

 allied to Bathycyathus. Holtenia Carpenteri and other rare Sponges, with 

 Brisinga endecacnemos and various Echinoderms equally interesting, formed 

 part of our treasures ; but the greatest prize of all was a noble Pentacrinus, 

 about a foot long, of which several specimens came up attached to the 

 tangles. This discovery of a true Pentacrinus in the European seas crowned 

 the day's work. Mr. Jeffreys has named it P. Wyville-Thomsoni ; Dr. 

 Carpenter will describe it, and give its zoological and geological relations, 

 as he is especially acquainted with this group of the Echinoderms by 

 having worked out the structure of Antedon in the Philosophical Trans- 

 actions for L866. We may remark that our Pentacrinus was dragged 

 up from soft mud or ooze, and that its base was entirely free. Portions 

 of the arms occurred in several other dredgings on the Lusitanian coasts ; 

 and joints of apparently the same species have been found by Professor 

 Seguenza in the Zanclean formation or older Pliocene near Messina. 



16. July 22nd. We tried to dredge among the Berling Isles, but 

 could do nothing. The ground was rocky, and the charts were incorrect. 

 The sounding-lead was deeply indented, and a water-bottle torn away and 

 lost. A dredge was afterwards put down twice in a trough or gulley 

 between 900 and 1000 fathoms deep ; each time it came up empty. We 

 then steamed for Lisbon, where we arrived the next day. 



17. On the 25th (Monday) we got to Cape Espichel. The wind had in-
