Synoicum bowerbanki Millar, 1963

Synoicum bowerbanki Millar 1963, p 697 ; Kott 1992a, p 480.

Distribution

Previously recorded (see Kott 1992a): Western Australia (Fremantle); Victoria (Portland Canyons). New record: Tasmanian Canyons (Banks Strait, 168 m) .

Remarks

The newly recorded specimen has been assigned to this temperate species on the basis of the upright club-shaped colony, narrowing to the base, identical with one previously reported from Portland, Victoria (see Kott 1992a, Figure 42a). The test is soft and translucent. The species is characterised principally by the presence of only four rows of stigmata and identification of the newly recorded specimen cannot be firm because zooids are in vegetative state, with minute regenerating thoraces and long vegetative posterior abdomina.
