A single but typical specimen was obtained at Station 48a, and it was 
! common at Station 297. From all the records this seems to be a circumpolar 
| species confined to the Arctic. Brady records it as far north as latitude 82° 
. 27’ N., in Smith sound, also from Baffin bay, Davis strait, and from the re- 
gion of Spitzbergen, Franz Josef land, and Nova Zembla. It. is known from 
the Siberian Arctic, recorded by Awerinzew. The work of Heron-Allen and 
Earland has extended the distribution to certain localities as far south as the 
east coast of Ireland.

Several specimens at station 297. I am referring to this species certain’ 
specimens found at this station. They are of the form and size of P. subnodosa, 
but like other arctic species of the genus there are developed double rows of 
pores along the sutures. This is one of the species recorded by Awerinzew 
from the Siberian Arctic. It may prove to be distinct from the form referred 
to this species from lower latitudes.

Specimens were picked out by the collector, giving clean examples for 
study, from stations 27s, 41, and 41c. I found a few young specimens in washing 
-the material from stations 29g and 29j. The large, well-developed specimens 
are filled with a yellowish brown protoplasm. The test in these Arctic specimens 
-is thicker and heavier than those from farther south, and the flaring condition 
of the test is not so early taken on. The largest specimen measured 10mm. in 
length, which seems to be a record for the species. Brady recorded the species 
from north of Smith sound and from Davis strait. Awerinzew records it from 
the Siberian Arctic, and Goés from Spitzbergen. Pearcey records it from the 
Antarctic, and it has been found in all the great ocean basins, but is much more 
common in the Atlantic than in the Pacific.
