At station 3 there were taken several specimens that evidently belong to this 
species as usually known. They are of the elongate form figured by Brady in 
the Challenger Report (pl. 56, fig. 1). It is recorded from Baffins Bay by Parker 
and Jones, and there are other records from various parts of the Arctic.

A single, two-chambered specimen was found in the bottom material from 
station 5. It is similar to the specimens figured by Brady, the test translucent 
and thin-walled. 
Awerinzew records this species from the Siberian Arctic.

A few specimens, somewhat compressed, resemble the figures given of this 
species. The specimens are translucent and thin-walled. They occurred at 
stations 3, 4, and 5. The species of Polymorphina, as recorded in the literature 
of this genus, are in a state of great confusion. From studies I have made of 
tropical material and that from cooler regions it seems that careful discrimination 
will result in definite distributions of a considerable number of species. 
Polymorphina lanceolata Reuss.

Forms referred to this species, as figured by Brady, are rare at station 5. 
The surface is smooth and polished and the sutures hardly depressed.
