XL. — Observations on the Ampliipoda occurring on the Nor- 

 wegian Coasts. By Axel Boeck*. 



Although the Ampliipoda occurring on the Norwegian coast 

 have been the subject of the investigations of several naturalists, 

 and valuable contributions to our knowledge of them are pub- 

 lished, it appears that continued investigations may furnish 

 important results, as we are probably far from having any- 

 thing like a complete knowledge of the forms which occur 

 there. 



When Milne-Edwards, in 1840, published the third volume 

 of his ' Histoire Naturelle des Crustace's,' in which the Amplii- 

 poda are treated of, only a few Norwegian species were known ; 

 but within a few years the number of the described species 

 was considerably increased by the investigations of H. Rathke, 

 Kroyer, Lilljeborg, and others. Quite recently our knowledge 

 has been much increased by the publication of Bruzelius's 

 memoir in the l Svenska Vetenskaps-Akademiens Handlingar ' 

 for 1858. In this he describes, from his own investigations, 

 some new species, and many previously known ones, in all 

 77 Scandinavian species, most of which occur on the coast of 

 Norway. This number, however, does not include any spe- 

 cies of the tribes Hyperida? and Caprellidge. To this number 

 must be added some new species which Professor Sars has de- 

 scribed in the ' Christiania Videnskabs-SelskabsForhandlinger' 

 for 1858, others which are mentioned by Danielsen in the list 

 of forms found by him on the coast of Finmark, published in 

 the 'Nyt Magazin for Naturvidenskaberne ' for 1858, and 

 some which are described in the ' Throndhiemske Videnskabs- 

 selskabs Skrifter' for 1858, from collections made by him at 

 Christiansund and Molde.
