Bundprøven blev benyttet. Denne Methode viste sig at 

 give udmærkede Resultater. 



Som Prøve paa de forskjellige Lersorters Fauna skal 

 her opregnes cle Arter, der ved Dr. Madsens Methode er 

 fund et i 5 Bundprøver, nemlig 1 fra Biloculinaleret, 1 fra 

 Overgangsleret, 1 fra det g-raa Ler langs Norges Kyst, 1 

 fra Rhabdamminaleret og 1 fra det graa Ler ved Spids- 

 bergen. Disse Bundprøver er ikke netop af de paa Arter 

 og Exemplarer rigeste, men udvalgt saaledes, at de ialmin- 

 delighed forekommende Arter saavidt mulig kommer med. 

 De er fra følgende Stationer: 9, 135, 296, 268, 368. 



Foruden Bundprøverne havdes ogsaa en hel Del 

 Tuber med Thalamophorer fra Skrabningerne. Disse Tuber 

 indeholdt ofte en stor Mængde af de større og mere iøine- 

 faldende Arter lt Da der ikke fancltes nogen saadan Prøve 

 fra Skrabningerne fra det graa Ler, skal der her blot 

 gives en Fortegnelse over de Arter, der ved Skrabningerne 

 er fundet paa 2 Stationer, nemlig en fra Biloculinaleret 

 (Station 40) og en fra Rabdamminaleret (Station 274). 



a litre of the sample was used. This method proved to 

 be productive of excellent results. 



The species found by Dr. Madseir's method in 5 

 bottom-samples will here be considered as samples of the 

 fauna of the different kinds of clay, viz. 1 from Biloculina 

 clay, 1 from transition clay, 1 from the gray clay along 

 the coast of Norway, 1 from the Rhabdammina clay, and 

 1 from the gray clay at Spitzbergen. These samples are 

 not of the richest in species and specimens, but are chosen 

 so as to include the species of most general occurrence. 

 They are from the following stations: 9, 135, 296, 268 

 -and 368. 



In addition to the bottom-samples, there were also a 

 number of tubes containing Thalamophora from dredgings. 

 These tubes often contained a considerable number of 

 large and conspicuous species x . As there was no such 

 sample from dredgings from the gray clay, a list will only 

 be given of the species found in dredging at 2 stations, 

 namely, one from the Biloculina clay (Station 40), and 

 one from the Rhabdammina clay (Station 274).
