tbe inter-nodes consist of only two very thin platelike
joints, so that tbe nodal joints Avith tbe rings of
cirri are croAvded together. The cirri start abruptly
from a single nodal joint as in P . asteria and in
P . loyville-tJiomsoni; they are robust, they consist
of about twenty-five joints, and in our specimen
tliev are c I o s c I a' curled doAvnwards. From the W 0.'
attitude of the cirri and from the appearance of
the end of the stem, there can he no doubt that this
specimen is complete, that it is mature, and that it
AA'as liA'ino’ in an unattached condition.<D Pentaerinus
maelearamis is thus very distinct from the three
hitherto recognised species P. asteria, P. miilleri and
P. loyville-thomsoni; perhaps it approaches the last
most nearly, hut it differs from it markedly in
the structure and arrangement of the arms, and
totally in the construction of the stem.
