At 22 they were attached to Buccinum cyaneum, one being in the centre 

 of the operculum of a living specimen. 



Specimens occurred at Stations 29e, 43a, and 436. At 43a they were 

 attached to shells of Area, Pseudamusium and Margarites. 



This is one of the very widely distributed species from the records. It is 

 very abundant in shallow cold waters. Awerinzew records it from the Siberian 

 Arctic, and Pearcey from six stations in the Antarctic.

Typical specimens were obtained from stations 23 and 43c. Brady records 

 it from as far north as latitude 82 33' N., as well as from Baffin bay, Smith 

 sound, Hunde islands, Davis strait, Nova Zembla, and Franz Josef land. 

 Awerinzew records it from the Siberian Arctic. It has been recorded from 

 warmer shallow waters as well, but it is possible that further study may show 

 these to be different species.

Specimens were rare at stations 43a and 43c. Brady records it from Arctic 

 localities north as far as latitude 82 33' N. in Smith sound, and from the shores 

 of Spitzbergen, Franz Josef land, and Nova Zembla. Awerinzew records it 

 at five stations in the Siberian Arctic. Pearcey records it from the Antarctic. 

 It has been found by Heron-Allen and Earland from the northern and western 

 coasts of the British isles. Most of the other records are from deep water, but 

 it has also been recorded from the Mediterranean, and the type locality is shore 

 sand from the Canaries. 



Polystomella striato-punctata Fichtel and Moll, var. incerta (Williamson). 



The varietal form of this species, with its fewer and more irregular depres- 

 sions along the sutural lines, was found at stations 206-c, 27s, and 29a. 



A great variety of forms have been included by writers under P. striato- 

 punctata, and as a result it is seemingly distributed wherever foraminifera are 

 found. Awerinzew has recorded var. incerta from the Siberian Arctic, and 

 Kiaer from the American Arctic. Williamson's original material was from the 

 British isles.
