Notes
Originally found in the Bass Strait between Australia and Tasmania, it has not been reported since.
The species was regarded as valid by von Lendenfeld (1884). However, Mayer (1910: 712) considered it (as A. aurosa) to be a young or reconstructed version of some other species; it was not treated by Kramp (1961).
Judging by the description and the accompanying illustrations, this is a very young rhizostome that cannot be positively identified to an adult species, and is better left as obsolete.
