deposit for their spawn, which invests the stems of Antennularia in transverse folds, so tightly
packed, that the windings cannot readily be traced. The ova are densely imbedded in a
flattened, gelatinous strap of moderate breadth; this does not form a continuous spiral, but
is reflected upon itself at each volution, so as to leave a small portion of the stem of the
coralline uncovered. We have taken the spawn in October. This is a very inactive animal,
moving slowly, and rarely swimming; when removed out of the water, on account of the
firmness of its tissues, it does not collapse like most of the Eolidid/z. The branchiae are very
apt to fall off, hence its name.
