8 HANS KIZR. 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 
be seen that very few of the species appear in any quantity. Among 
the characteristic species of more general occurrence may be mentioned 
the large and beautiful forms, Hyperammina nodulosa and Haplo- 
phragmium canariense, of which vigorous and well developed speci- 
mens appear in Gaase Fjord. Spiroplecta biformis, Nodulina arctica 
and Teatularia Williamsonii are also species that are found in the 
sane localities in comparatively large numbers. Among the adherent 
forms occurring are the cosmopolitan Truncatulina sp. and the Poly- 
stomella striatopunctata var. incerta. 
The arctic nature of the fauna is shown by the occurrence of large 
and sometimes well-developed specimens of Polystomella arctica, and 
further by the small, but characteristic forms, Cassidulina crassa and 
Pulvinulina karsteni. Spiroplecta biformis and Nodulina 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. striata) in these bottom 
samples, this being in mud from the upper part of Gaase Fjord, from a 
depth of 15 fathoms. The Lagena species are usually well represented 
in the arctic and boreal bottom deposits.
