8 HANS KLER. ON THE BOTTOM DEPOSITS. [SEC. ARCT. EXP. FRAM 



Remarks on some of the Species of Foraminifera. 



On looking at the list of the Foraminifera from the stations, it will 

 lit- -een that very few of the species appear in any quantity. Among 

 the characteristic species of more general occurrence may he mentioned 

 the la rye and beautiful forms. Hyperammina tiotlitloxd and Haylo- 

 /iltKKjniiiuH CdtHU'ienw. of which vigorous and well developed speci- 

 men- appear in (iaa>e Fjord. */>ir<>i>l<'c/<f hifonnix, .\oilnlina arctica 

 and '!'<. i-lnlni-'xt \\'illi(unnnitii are al>o specie?-, that an- found in the 

 -ame localities in comparatively large numbers. Among the adherent 

 forms occurring are the cosmopolitan Truncatulina sp. and the Polif- 

 xtoiiH'Uu striatopunctota var. incerta. 



The arctic nature of the fauna is shown by the occurrence of large 

 and sometimes well-developed specimens of Polystomella (irclica. and 

 further by the small, hut characteristic forms. < 'assiduiina crassa and 

 I'lilfiimlimi karstoii. Spiroplecta biformis and Noduliua arctica are 

 also of arctic origin. 



The rare occurrence of the Lagena forms is to be noted. I found, 

 in fact, only a single specimen of Lagena (L.ntrixfd] in these bottom 

 -amplr-. this being in mud from the upper part of Gaase Fjord, from a 

 depth of [~> fathoms. The Lagena species are usually well represented 

 in the arctic and boreal bottom deposits.
