1 he material, of which this paper is the outcome, was for 

 the most part collected in the fjords round Bergen by Dr. Nord- 

 gaaed and by myself in the summer of 1901 and 1902. Dr. Nord- 

 gaard also very kindly placed at my disposal several specimens 

 obtained from round Bergen in the autumn of 1901, together 

 with a collection which he had previously made during an expe- 

 dition to Lofoten in the winter of 1899. With his name I have 

 much pleasure in associating one of the most characteristic forms 

 from the last named area, in recognition of the care which he 

 expended in procuring these worms and of the kindness and courtesy 

 I experienced at his hands whilst working in Bergen. 



Our previous knowledge of the members of this group inhabiting 

 the Norwegian fjords is principally due to the older authors 0. F. 

 Muller, 1 ) Orsted, 2 ) and Rathke, 3 ) together with Jensen in more 

 recent years. In his work on the Norwegian Turbellaria 4 ) Jensen 

 has revised the Nemertean fauna of Norway up to the year 1878. 

 From that date, though Bergendal has been publishing on the Swe- 

 dish forms, nothing more has been written on the Norwegian nemer- 

 teans. As the present paper more than doubles the number of 

 species belonging to the fauna of Norway, partly by adding new 

 species and partly by recording species already known from else- 

 where, a complete list of them has been drawn up (p. 4). From 

 this it will be seen that by the inclusion of 7 previously known 

 species not hitherto recorded from Norway, and by the description 

 of 12 new forms, the list of Nemerteans from this part of the world 

 has been raised from 15 to 34. That this however is far from
