XL. — Observations on the Ampin poda occurrincj on the Nor- 

 wegian Coasts. By Axel Boeck*. 



Although the Amphipoda occuiTing on the Nonvegian coast 

 have been the subject of the investigations of several naturalists, 

 and valuable conti-ibutions 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. 



^-Mien Milne-Edwards, in 1840, published the third volume 

 of his ' Histoire Naturelle des Crustacds,' in which the Amphi- 

 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 Binizelius's 

 memoir in the ' 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 Avhich occur on the coast of 

 Norway. Tliis number, hoAvever, does not include any spe- 

 cies of the tribes Hyperida? and Caprellida?. To tliis number 

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

 scribed in the ' ChristianiaYidenskabs-SelskabsForhandlinger' 

 for 1858, others wliich arc mentioned by Danielsen in tlie list 

 of forms found by him on tlie coast of Finmark, publislied in 

 the ' Nyt Magazin for Xaturvidenskabenie ' for 1858, and 

 some which are described in the ' Throndliiemske Videnskabs- 

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

 Christiansund and ^lolde.
