Polypompholyx multifida W. Australia

The bladders grow in a whorl at on the summit of a stiff stalk.

The free part of the antennæ is represented by a minute membranous fork— the basal or united part being expanded so as to form a kind of hood surrounding the orifice, the hood is expanded into two lateral wings; the bladder has a 3 winged appearance on account of the presence of a dorsal ridge continuous behind with the dorsal part margin of the petiole— The structure of this hood was very difficult to be sure about — The inner surface of the hood is lined with long simple hairs with coagulated coul or shrunk contents like quadrifids in a bladder that has caught something

There is a valve but I cannot determine its structure; also numerous one celled glands* with a short stalks in the neighbourhood of orifice— Quads of 4 equal cells [sketch]

Catches entomostraca

P. tenella smaller but apparently the same general structure— Bladders full of "dirt" but I could find no articulate remains—
