186 THE DEPTHS OF THE SEA. [CHAP. iv. 



Several undescribed crustaceans were added ; a new 

 species of the genus Cwnocyathus among the corals, 

 and a species of an mumown genus allied to Bathy- 

 cyathus. Brisinga endecacnemos and some new ophi- 

 urids were part of the treasures, but the greatest 

 prize was a splendid Pentacrinus about a foot long, of 

 which several specimens came up attached to the tan 

 gles. This northern Sea-lily, on which my friend Mr. 

 Gwyn Jeffreys has bestowed the name Pentacrinus 

 wyville-thomsoni, will be described hereafter with some 

 other equally interesting members of the same group. 



Cape Espichel was reached on the 25th. The 

 weather was now, however, so rough that Captain 

 Calver was obliged to take shelter in Setubal Bay. 

 Professor Barboza de Bocage of Lisbon had given 

 Mr. Gwyn Jeffreys a letter of introduction to the 

 coastguard officer at Setubal, who knew the place 

 where the deep-sea shark and the Hyalonema are 

 taken by the fishermen, but the state of the weather 

 prevented his taking advantage of it. 



Off Cape Espichel in 740 and 718 fathoms, with a 

 temperature of 10*2 C., the mollusca were much the 

 same as those from Station 16, but included Leda 

 pusio, Limopsis pygmcea (Sicilian fossils), and Verti- 

 cordia acuticostata. The last-named species is in 

 teresting in a geological as well as a geographical 

 point of view. It is fossil in the Coralline Crag 

 and the Sicilian Pliocene beds, and it now lives in the 

 Japanese archipelago. Mr. Jeffreys suggests a mode 

 of accounting for the community of so many species 

 to the eastern borders of the Atlantic basin and the 

 Mediterranean, in which several Japanese brachi- 

 opods and crustaceans are found, and the seas of
