give en saavidt muligt kortfattet systematisk Over- 

 sigt af samtlige hidtil kjendte norske Arter, hvor- 

 ved der er lagt hovedsagelig Vægt paa dets prak- 

 tiske Anveudeliglied ved Artsbestemm eisen, mindre 

 paa det 3-di'e Udst\T eller paa en mere indgaaende 

 anatomisk Behandling af de enkelte Former. Jeg 

 tror, at zoologiske Arbeider udarbeidede efter ethvert 

 af disse Principer har sin fulde Berettigelse og Nytte 

 Side om Side, og skulde ogsaa af denne Grund onske, 

 at Fauna Norvegio? blev forbeholdt mere udforlige 

 Monograpliier af enkelte mindre kjendte Dyreformer 

 eller af begrændsede Grrupper, der maatte frem- 

 byde en særlig Interesse i anatomisk-biologisk Hen- 

 seende. 



Plancherne til nærværende Bind er i sin Tid 

 udforte paa nu afdode Lithograf Lynglis Officin, og 

 ved deres Udforelse er anvendt al den Omhyggelig- 

 hed og Kunst, som da kunde jiræsteres, saavel hvad 

 Lithographering som Farvetrykning angaar. Texten 

 er i Lighed med de 2 sidste Bind af Fauna littoralis 

 og med Nordhavs-Expeditionens Generalberetning, 

 dobl)eltspaltet, den ene Spalte norsk, den anden en- 

 gelsk. Oversættelsen af de 6 forste Ark er besørget 

 af nu afdode Translateur Wilson, Resten af Miss 

 Jessie Miiir. 



Idet jeg herved fremlægger for Offentligheden 

 Iste Bind af Fauna Isorvegiæ, sker det med det 

 Haab, at der maa gives vore fremtidige Zoologer 

 Anledning til at fortsætte dette Værk med flere 

 paafolgende Bind udstyrede paa en for vort Land 

 værdig Maade.

systematic survey of all the hitherto known Nor- 

 wegian species, whereby special importance is laid 

 on its practical applicability in the determination 

 of species, and less on its external get-up. or on a 

 more detailed anatomical treatment of the various 

 forms. I think that zoological works written on 

 these two principles are perfectlj- legitimate and 

 useful side by side ; and I therefore wish that Fauna 

 Norvegiæ could be kept for more detailed mono- 

 graphs on certain less familiar animal forms, or of 

 limited groups that offered special interest in an 

 anatomical-biological direction. 



The plates to the present volume were executed, 

 in their time, in the late lithographer Lyngh's 

 printing-office, and all the care and art of which 

 that time vs^as capable, both as regards lithography 

 and colour-printing, were employed in their execu- 

 tion. The letter-press is similar to that of the last 

 2 volumes of Fauna littoralis^ and to the General 

 Report of the North Atlantic Expedition, being in two 

 columns, the one column Norwegian, the other Eng- 

 lish. The translation of tlie first 6 sheets was made 

 by the late Mr. Wilson, translator, the remainder 

 by Miss Jessie Muir. 



In now presenting the first volume of Fauna 

 Norvegiæ to the public, I do so in the liojie that 

 opportunity may be given to our future zoologists 

 to continue this work with successive volumes, got 

 up in a manner worthy of our country.
