have clarified the systematics and relationships of the Antarctic forms.
There is apparently only one Antarctic species, P r i q u l u s tuberculatospinosw Baird which has been recorded from East Antarctica, the
Antarctic Peninsula, the South Orkneys and South Georgia, as well as
from New Zealand, Macquarie Island and southern South America. It
is also known from scattered deep-water stations. Shipley (1902)
recorded Priapulus caudatus Lamarck from two specimens washed
ashore at Cape Adare at the entrance to the Ross Sea. One of these
specimens has been examined by van der Land (1970) who found that
rather surprisingly it agreed better with the northern P. caudatus than
with P . tuberculatospinosus but preferred to base no conclusion upon
this rather anomalous record.
The example of bipolarity which the group has been supposed to
show rather dissolves as a result of the recognition of P . caudatus as
an essentially northern form and P. tuberculatospinosus as essentially
southern (Lang, 1951) and the recognition of Priapulus as a widespread
deep-water genus (Murina and Starobogatov, 1961; van der Land,
1970).

The main contributions to our knowledge of Antarctic sipunculid
worms have been: ThBel (1911), Stephen (1941, 1948), Murina (1964)
and Edmonds (1965, 1969). This is one of the difficult groups to
classify, and also m e of the groups from which evidence of bipolarity
has been taken.
Only the two genera GolJingia and Phascolion have so far been
recorded from the Antarctic, the commonest Antarctic species being :
GolJingia margaritacea capsiformis (Baird) ,
G. anderssoni (ThBel),
G. mawsoni (Benham),
G. ohlini (ThBel)
G. nordenskjokli (ThBel),
Phascolion strombi (Montagn).
Probably all the species of Goljingia listed above are circumThere is some indication (Murina, 1964) that some of the species
