Family FIMBIUIDlE.
Genus Propemelibe, gen. novo
Ol'thotype, Propemelibe mirifica, sp. novo
Animal very large and showy, gelatinous, elliptical in shape, with a constricted
neck and the head enlarged into an enormous rounded fringed veil with thickened
edges. This veil is about half the size of the main part of the body. Rhinophol'es
about half-way down the veil, set fairly well apart and retractile into truncate
sheaths with minute stalks. Dorsal surface of the animal covered with irregular
f1ized pustules and branched filaments, including the cerata. Cerata arranged in a
single row along each side, very large when fully grown, about 5-7 along each side.
Foot very broad, mouth at the base of the veil, with thickened lips, no radula,
but minute jaws. A dark belt of horny processes lines the lower portion of the
posterior part of the stomach. Liver divided, extending to the cerata.
I have been compelled to create this new genus for the very interesting and
hitherto unrecorded species described below, because of the difficulty experienced
in placing it definitely in either of the two genera it resembles. Externally it
resembles the genus FimbTia Bohadsch, 1761/ but, on the other hand, it has
several internal characters of the genus Melibe Rang, 1829.2
