Periphylla

Remarks. This is the first record of the genus Periphylla in Australia. These specimens are similar in general morphology to a California form studied by the senior author. The bell is small, transparent, and conical, with a deeply red-pigmented stomach; the 12 tentacles occur in four groups of three between four interradial rhopalia. Currently most workers recognize only one species, P. periphylla, although many nominal species have been described in the past. A revision of the genus appears warranted but is beyond the scope of this paper.
