the antenn . These are broad, flattened, and of large size; they bear
on their margins multicellular hairs, surmounted by glands. Their bases
are united into a single, rather narrow pedicel, and they thus appear
like a great digitate expansion at one end of the bladder. Internally
the quadrifid processes have divergent arms of equal length. The
bladders contained remnants of articulate animals. [page 445]
POLYPOMPHOLYX.
This genus, which is confined to Western Australia, is characterised by
having a quadripartite calyx. In other respects, as Prof. Oliver
remarks,* it is quite a Utricularia.
Polypompholyx multifida. The bladders are attached in whorls round the
summits of stiff stalks. The two antenn are represented by a minute
membranous fork, the basal part of which forms a sort of hood over the
orifice. This hood expands into two wings on each side of the bladder.
A third wing or crest appears to be formed by the extension of the
dorsal surface of the petiole; but the structure of these three wings
could not be clearly made out, owing to the state of the specimens. The
inner surface of the hood is lined with long simple hairs, containing
aggregated matter, like that within the quadrifid processes of the
previously described species when in contact with decayed animals.
These hairs appear therefore to serve as absorbents. A valve was seen,
but its structure could not be determined. On the collar round the
valve there are in the place of glands numerous one-celled papillae,
having very short footstalks. The quadrifid processes have divergent
arms of equal length. Remains of entomostracan crustaceans were found
within the bladders.
Polypompholyx tenella. The bladders are smaller than those of the last
species, but have the same general structure. They were full of dbris,
apparently organic, but no remains of articulate animals could be
distinguished.
