Polycarpa viridis Herdman, 1880  

Polycarpa viridis Herdman 1880, p 74   ; Kott 1985, p 208 and synonymy.

Distribution

Previously recorded (see Kott 1985): Western Australia (Cockburn Sound); South Australia (Great Australian Bight, Spencer and St Vincent Gulfs); Victoria (Bass Strait); New South Wales (Cape Jervis, Port Jackson). New records: Tasmanian Canyons ( Pieman Canyon , 168 m, 174 m)   .

Description

The newly recorded specimens are of the usual conservative form for this species, with an atrial aperture about one-third of the body length distant from the terminal branchial aperture. Both apertures are on small conical protrusions and props or hair-like roots are on the postero-ventral part of the body. The gonads are embedded in the body wall amongst large spherical blister-like vesicles and a large fleshy endocarp is in the rather short postpyloric part of the gut loop and there is the usual long rectum. The preservative of one of the specimens is orange-red and the specimen itself is a maroon colour, although this may have been affected by other specimens preserved with it.

Remarks

There is no trace of the green colour said to characterise this species and its distinction from P. flava   depends greatly on its rather thin test without sand while the latter species has a thicker, tougher test, black in preservative.

Monandrocarpa plana: Kott 1985, p 210   and synonymy.

Distribution

Previously recorded (see Kott 1985): New South Wales (Cronulla); Philippines. The species has been taken from the Philippines on rocks supplied to the aquarium industry. New records: Queensland (18.015 ° S, 146.645 ° E, 55 m) GoogleMaps   .

Description

The newly recorded colony is a collection of small grey domes, each to 1 cm diameter with sessile apertures on the upper surface, the branchial aperture halfway between the atrial aperture (in the centre) and the anterior margin of dome. The whole of the lower flat surface adheres to the substratum. The test is thin and slightly translucent. Sometimes the basal test spreads out around the zooids, but a connection between them was not detected. The stomach is folded. About 10–12 hermaphrodite polycarp gonads, each consisting of a sac-like ovary associated with a single testis follicle, are in a row along each side of the endostyle.
