nother, and sometimes vividly illuminating the whole 

 j utline of the star-fish. 



On the 27th we dredged in 862 fathoms (Station 42), 

 he weather heing still very fine, and the sea quite 

 mooth. The bottom was ooze, with sand and dead 

 hells. Among the Mollusca procured were a new 

 pecies of Pleuronectia, Leda abyssicola (Arctic), Leda 

 lessinensis (a Sicilian tertiary fossil), Dentalium 

 I gas (sp. n.), Siplionodentalium (sp. n.), Cerithium 

 wtula, Amaura (sp. n.), Oolumbella haliceeti, CylicJma 

 yramidata (Norwegian and Mediterranean), and 

 lany dead shells of Cavolina trispinosa. These 

 itter were very common in all the northern dredg- 

 igs, though we never saw a living specimen on the 

 irface. 



During the afternoon we took a series of inter- 

 lediate temperatures, at intervals of 50 fathoms, from 

 'ie bottom at 862 fathoms to the surface. 

 On the 28th we dredged in 1207 fathoms (Station 

 3), with a bottom of ooze. A large Fusus of a new 

 )ecies (F. attenualus, Jeffreys) was brought up alive, 

 ith two or three Gephyrea, and an example each of 

 ] pliiocten sericeum and Echinocucumis typica. "We 

 >ain dredged on the 29th and 30th, gradually draw- 

 ig in towards the coast of Ireland in 865, 458, 180, 

 ad 113 fathoms successively (Stations 44, 45). In 

 '58 fathoms (Station 45) we procured a broken 

 Sample of Brisinga endecacnemos, previously taken 

 ly Mr. Jeffreys off Valentia, and a number of 

 tteresting Mollusca ; and in 458 and 180 fathoms 

 Stations 45 and 45a) an extraordinary abundance of 

 limal life, including many very interesting forms
