Distribution

Previously recorded (see Kott 1985): Western Australia (Kendrew I., Shark Bay , Cape Jaubert); Victoria (Bass Strait); Queensland (Capricorn Group, Abbot Point, Twonsville, Cleveland Bay, Lloyd Bay, Cape Melville, Murdoch Point); Indonesia, Madagascar, Sri Lanka. New records: Queensland (15.495 ° S, 145.385 ° E, 25.6 m; 17.445 ° S, 146.205 ° E, 26 m; 17.605 ° S, 146.355 ° E, 39 m; 17.655 ° S, 146.225 ° E, 26.5 m; 18.035 ° S, 146.205 ° E, 18 m; 18.615 ° S, 146.645 ° E, 30.5 m) GoogleMaps   .

Description

Flabby translucent whitish test covered in shell fragments and adherent and semiembedded sand. Apertures close on anterior surface, often obscured by rough test although the siphons often are naked. Row of eight relatively long polycarps down middle of each side of the body. Tall, rather leaf-like endocarps in gut loop and long, finger-like anal lobes,

the usual pointed spines are around and in the siphon linings. Newly preserved material is bright yellow, the colour especially conspicuous on the naked siphons.

Remarks

Only a single specimen was taken from each newly recorded location. Kott (1985) reported red-coloured specimens of this species, although relatively freshly preserved newly recorded specimens are bright yellow.

Polycarpa papillata ( Sluiter, 1885)  

Styela (Polycarpa) papillata Sluiter 1885, p 192   .

Polycarpa papillata: Kott 1985, p 184   and synonymy.

Distribution

Previously recorded (see Kott 1985): the species has been recorded from all around the Australian continent, Indonesia, the western Pacific and Madagascar. New record: Tasmanian Canyons (King I. Canyon, 249 m).

Remarks

The species characteristically ejects its gut, including the pharynx, through the atrial siphon when collected. Despite variations, its general body shape, with short cylindrical siphons separated by half the body length, help to distinguish it, as does its white test with strips of pink-red colour.

The species has a wide range through the Indo-West Pacific. The new record from the Tasmanian Canyons represents the most southerly location yet reported.
