Piden 2 det Hefte af Fauna littoralis Norvegiæ 

 udkom, er der hengaaet en meget lang Tid, og i 

 dette lange Tidsrum har Døden bortrevet vor Ven 

 og Medarbeider Professor, Dr. Michael Sars. Li- 

 gesom hans Bortgang var et stort Tab for den 

 zoologiske Videnskab, saaledes vil ogsaa Savnet, 

 han efterlod sig i sit Fædreland, længe blive følt. 

 Hans grundige og omfattende Forskninger for- 

 skaffede ham en Berømthed, der gjennem alle 

 Tider vil kaste Glands over det Land, han til- 

 hørte. 



Hans Minde være 3die Hefte af Fauna litto- 

 ralis ISTorvegiæ tilegnet. 



Mange Omstændigheder have bidraget til at 

 dette Hefte, til hvis Udgivelse Storthinget med 

 dets sædvanlige Liberalitet har ydet et Penge- 

 bidrag af 4000 Kroner, først nu udkommer. 



I videnskabelig Henseende leve vi her tem- 

 melig isoleret, blottet for en god Del af de Hjel- 

 pemidler, der i høi Grad lette Udgivelsen af et 

 saadant Arbeide, som det foreliggende. Det eneste 

 Bibliothek, foruden vor private Bogsamling, som 

 findes her paa Stedet, er Museets, og dette er 

 saa mangelfuldt, baade hvad den ældre og nyere 

 Literatur angaar, at vi langveis fra have maattet 

 forskaffe os de nødvendigste literære Hjelpemid- 

 ler. Men hvad der dog mest har bidraget til at 

 forsinke Udgivelsen, er den Omstændighed, at her 

 kun er een Kunstner, til hvem vi kunde over- 

 drage Udførelsen af Lithographierne, — og denne 

 Mand har i Aarvis opholdt os, hvorfor vi ogsaa 

 have været nødtvungne til i Uddrag at publicere 

 en Del af de Afhandlinger, som findes i dette 

 Hefte. Alt dette vil forhaabentlig tjene os til 

 Undskyldning for de Mangler, der maatte klæbe 

 ved Arbeidet. 



Vi skylde at tilkjendegive Hr. Overlæge G. 

 Armauer Hansen vor forbindtligste Tak for den 

 Assistance, han har ydet os ved de histologiske 

 Undersøgelser.

PREFACE. 



W e have been obliged to allow a very long time 

 to pass, since the second part of Fauna littoralis 

 Norvegiæ appeared. In the interval between that 

 time and now, death has deprived us of our highly 

 esteemed friend and collaborator, Professor, Dr. 

 Michael Sars. As his decease was a great loss 

 to zoological science, all those who knew and 

 loved him in our Fatherland, will miss him ex- 

 tremely much and long. The excellence and pro- 

 ! fundity of his thoroughgoing inquiries, gave him 

 a celebrity which, throughout all times, will throw 

 a lustre on the country to which he belonged. 



We therefore consecrate the present third 

 part of Fauna littoralis Norvegiæ to his memory. 



With its usual liberality, our National As- 

 sembly (Storthing) has granted us 4000 Crowns 

 to enable us to publish this part of the present 

 work, but many circumstances have contributed 

 to prevent us from making it appear before now. 



In all scientific respects we live here rather 

 isolated, devoid of the greatest part of all the 

 aids, that would have made the publication easier 

 of a work of this kind. Besides our private li- 

 braries, there is no library existing in our town, 

 except the one in our Museum, which however is 

 so deficient as to all literary matters both of 

 elder and of a more modern date, that we have 

 been obliged to procure from distant places all 

 the literary aid required. But what even more 

 has retarded the publication of the present work, 

 is that we have but one artist in our town, whom 

 we could trust with the lithographies necessary. 

 And most unfortunately he has occasioned a delay 

 of several years. We have therefore been obliged 

 earlier to publish some extracts of the treatises 

 now found here. We also hope that all these 

 unfortunate circumstances will plead for us, if the 

 deficiencies of this work should prove too apparent. 



We give our best and sincerest thanks to the 

 chief-physician, Mr. G. Armauer Hansen, for the 

 valuable assistance he has given us through his 

 histological researches.
