DEEDGING STATIONS OF THE KNIGHT ERRANT, 1880. 



The dredgings of the British steamer Knight Errant were made in the 

 Fiiroe Channel between the Faroe Islands and the north of Scotland, 

 covering a part of the same ground that was explored by the Lightning 

 in 1868, and defining the position of the submarine barrier by which the 

 so-called warm and cold areas of the Faroe Channel are divided from each 

 other. The report of the expedition was published in the Proceedings 

 of the Royal Society of Edinburgh, Yol. XI, pp. 638-720, read May 15, 

 1882. The dred.gings were under the scientific charge of Mr. John Mur- 

 ray, of the Challenger expedition.

DREDGING STATIONS OF THE TRITON, 1882. 



The dredgings of the British surveying steamer Triton in 1882 were, 

 like those of the Knight Errant in 1880, directed towards the further 

 exploration of the Faroe Channel, and covered nearly the same ground. 

 They were also under the scientific charge of Mr. John Murray, and Mr- 

 J. Gwyn Jeffrey's report on the mollusca obtained was published in tlie 

 Proceedings of the Zoological Society of London, June 10, 1883, from 

 which these positions have been taken.
