ROSEA.

A
species
which
has
the
cells
in
pairs
on
opposite
sides
of
the
central
tube,
with
the
openings
turned
outwards.
In
the
more
enlarged
figure
is
seen
a
septum
across
the
inner
part
of
each
cell
which
forms
the
base
upon
which
the
polype
rests.

This
Zoophyte
twines
itself
parasitically
upon
a
species
of

cells
in
this
species
are
thrown
out
at
irregular
intervals
upon
flexible
stems
which
are
wrinkled
in
rings.
They
consist
of
lengthened,
cylindrical,
transparent
vases.

A
still
more
beautiful
species,
with
lengthened
foot-stalks
ringed
at
each
end.
The
polype
is
remarkable
for
the
protrusion
and
contractile
power
of
its
lips.
It
has
about
twenty
knobbed
tentacula.
