186 THE DEPTHS OF THE SEA. [CHAP. IY. 
Several undescribed crustaceans were added ;—a new 
species of the genus Cenocyathus among the corals, 
and a species of an unknown 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 pygmea (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
