"Beania erecta sp. nov.

(Pl. I, figs 8a-e)

Besides a specimen from 1012, in which the chief characters can be deciphered, there is a small imperfect one from 343.

The zooecia are erect, as in B. crotali Busk, B. hirtissima, var. conferta MacG., and B. fragilis Ridley, in all of which the connections occur at the base of the zooecium and the radicle also grows from the lower part. The oral aperture is large, and on each side, above the aperture, there is a rudimentary spine. On the side of the zooecium a large capitate avicularium is articulated, having a much prolonged mandible, and the mandibles have the double columella characteristic of B. magellanica B., and B. bilaminata Hincks, while the avicularium is broader than that of B. magellanica Busk.

The shape of the appendage of B. crotali B. in a specimen from Port Phillip Heads is exactly similar to the mandible of B. erecta, even to the contraction at the distal end, where the narrow mandible terminates, and it seems probable that B. crotali B. is degenerate B. erecta, having the appendages without mandibles. Upon putting a zooecium from spirit to water it quickly became much inflated, and the lateral walls between the attachment of the muscles bulged out, and was very transparent, showing the muscles through the walls (figs. 8c-d).
