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 43b. At 43a they were 
attached to shells of Arca, 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.

Mus., pt. 4, 1914, p. 23, pl. 17, fig. 3. 
Typical specimens were obtained from stations 23 and 48c. 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 20b-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.
