BRACHIOPODA IN THE FAROEISLANDS AREA
invertebrate fauna of the Faroe Islands at
depths deeper than 100 m in order to sup-
plement and update previously published
information. A bibliography of benthic ma-
rine invertebrates of the Faroese Economic
Exclusive Zone has recently been pub-
lished by Bruntse and Tendal (2001).
Nørrevang et al. (1994) give an account
of the sampling, databases and a complete
list of sampling stations with details of lo-
cation, date, water depth, applied gear and
environmental parameters (bottom temper-
ature, water mass, bottom current velocity,
sediment etc.). This list include five sta-
tions sampled by T. Brattegard in 1983 and
13 stations sampled by T. Brattegard and J,-
A. Sneli in 1986-1987 (Brattegard and Me-
land, 1997). An overview of the benthic
temperature in the investigated area was
presented by Westerberg (1990). The main
part of the sampling took place during
1987-1990 and 1991-1993, mainly from
depths of 100-1000 m. Altogether ca. 600
localities were sampled.
Material and methods
The main part of the BIOFAR material de-
scribed in this paper was recovered by the
Faroese R/V ” Magnus Heinason” and the
Norwegian R/V "Hákon Mosby” using
benthic sampling gear (cf. Nørrevang et al.,
1994). Brachiopods were present in sam-
ples from 187 stations. They were collected
with five different gears: a heavy and stur-
dy triangular dredge (97 stns/ca. 52%), a
detritus sledge (60 stns/ca. 32%), a scallop
dredge (13 stns/ca. 7 %), a fine-meshed
Crania anomala x 2,3 Thomsen 2001
bottom trawl (10 stns/ca. 5%), and a modi-
fied Rothlisberg and Pearcy epibenthic
sampler (7 stns/ca. 4%).
The brachiopods were fixed in strongly
buffered 4% formaldehyde-seawater, later
replaced by 70% ethanol, and were prelimi-
nary sorted out from the other fauna by the
staff of the Kaldbak Marine Laboratory.

Information on each species follows the
scheme of Brattegard and Meland (1997).
