NOTES ON SOME RARE MOLLUSCA FROM THE NORTH 

 SEA AND SHETLAND-FAEROE CHANNEL. 



By JAMES SIMPSON. 



(Read before the Society, April 13th, 1910). 



Ever since the inauguration of the international scheme for the 

 investigation of the North Sea, hut more particularly since 1905, 

 extensive trawlings and dredgings have been done by the Scottish 

 Fishery Board steamer, "(joldseeker," in the North Sea and Slietland- 

 Faeroe Channel. 



The following notes have reference only to the work done in the 

 years 1905-6-7, and to the rarer species and varieties, or those 

 whose range is geographically or bathymetrically extended witliin 

 the British area. Complete lists of all the mollusca collected will, 

 in due course, be published by the bureau. 



To my old friend, Mr. J. T. Marshall, and to Herr Friele my 

 thanks are due for the verification of some of the more obscure 

 species ; and to Prof. Darcy W. Thompson, director of the in- 

 vestigations, for allowing me to work out the material. . 



The following is a list of the stations as given in the published 

 list. The depths are those from which the dredgings were taken up.
