tegat; North Sea; coast of the Netherlands; coast of
Belgium; northern coast of France?; coasts of Great
Britain; Ireland; Shetland; Faroes; Iceland; coasts of
Greenland; northern North America (Millar, 1966).
General distribution: The boreal western Atlantic; bo-
real eastem Atlantic; Lusitanian; Mediterranean; and
the Arctic.
General depth range: From low tide level (Berrill, 1950)
to 1600 m (Liitzen, 1959).
Remarks: P.fibrosa is also common in thc boreal west-
em Atlantic, where it probably dispersed either from
the Arctic or the boreal eastcrn Atlantic, a topic dis-
cussed by Lutzen (1959). The genus has a number of
other representative species further south along the
eastern coast of America in the Carolina region (Van
Namc, 1945); however, P.fibrosa is the only borcal
western Atlantic representative Polycarpa.
