8 NORMAN: ON THE MOLLUSCA OF BERGEN FIORDS. 



will not decide the question. What is required to determine 

 that the one is a variety of the other is a series showing a grada- 

 tional lapse from L. glutinosa the typical, to L. involuta the 

 abnormal. If these are not forthcoming the two must hold their 

 present relative position; but it is quite possible that there are 

 specimens already in the cabinets of those interested, which can 

 add another arch or two to bridge the gap. If there are, I hope 

 we shall soon hear of them and be rid of the anomaly of a species 

 unknown to the rest of the world, occupying its solitary tarn in 

 the British Isles.

THE MOLLLUSCA OF THE FIORDS NEAR BERGEN, 



NORWAY. 



By the Rev. A. M. NORMAN, M.A. 



The investigation of the fauna of the Shetland Seas during 

 many years occupied my spare time. As a member of the 

 Shetland Dredging Committee, appointed by our British Associa- 

 tion to report oo the Zoology of our most northern waters, many 

 summer holidays were devoted to this special work, in company 

 with Dr. Gwyn Jeffreys, Mr. Waller, and other naturalists.* I 

 have long felt that it would be a subject of much interest to 

 accurately compare with the Invertebrata of Shetland those of 

 that portion of this Norwegian coast which lies in the same 

 parallel of latitude. This wish long entertained has this year in 

 some degree been satisfied. The end of April found me landing, 

 in the companionship of my old friend Mi\ Jeffreys, at Bergen, 

 and the greater part of May was spent in dredging the Fiords to 

 the north and south of that town.
