colour, with internal shell visible through the
mantle shield. Cephalic shield without
tentacles and/or visible eyes but is adorned
with small but closely placed white dots.

coloured. The mantle shield is open at the
posterior end. Parapodia are short and do not
meet at the centre. The general shape is
more oval than elongated.
Generally found sublittorally on gravel where
it is well camouflaged.
Size range: 15mm. Uncommon.
Specific characteristics: Many similar
species and identification is based on size,
colour and shell (internal) ornamentation
which generally requires dissection.
