many more known forms, thus showing that the fauna north- 

 ward does not change very materially from that existing 

 further south in Davis Straits. 



In the report of the ' Valorous ' Expedition, Dr. Gwyn 

 Jeffreys gives it as his opinion that the molluscan fauna of 

 West Greenland is rather European than American. On the 

 contrary, the small collections brought home by the present 

 expedition lead to an exactly opposite conclusion ; for, of 

 the thirty-four species obtained, at least sixteen are found off 

 the Atlantic coast of the United States, whilst only four or five 

 have been recorded from European seas, and the remainder, as 

 far as our present knowledge extends, are exclusively Green- 

 landic. 



Great praise is due to the two naturalists of the expedition, 

 Captain H. W. Feilden, of H.M.S. ^ Alert/ and Mr. H. C. 

 Hart, of the ' Discovery,' for the careful manner in which the 

 particulars regarding the specimens are preserved. To save 

 repetition, the exact position of the principal stations at which 

 Mollusca wxre dredged is here appended : —
