Pareugyrioides galatheae

Description

Pareugyrioide s galatheae (Millar, 1959)

(®gure 30)

Molgula galatheae Millar, 1959: 202.

Pareugyrioides galatheae: Kott, 1969: 161; Monniot and Monniot, 1977b: 316; 1982: 124; 1983: 116.

Material examined. St. 914, 5650±6070 m, three specimens; st. 916, 4664±5631 m, one specimen.

Remarks. The anatomy of the present specimens is identical with that of the specimen described by Monniot and Monniot (1977b) from the south Indian Ocean. The specimen ®gured by Kott (1969: 160) has a diOEerent position of the right gonad, its proximal end`lies against and overlies’ the dorsal border of the renal sac. In the present material (®gure 30) the right gonad is separated from the antero-dorsal end of the elongate renal sac, as originally described and as ®gured by Monniot and Monniot (1977b). At present it is di cult to decide if the diOEerence described is intraspeci®c variation. The most peculiar character of the species is the presence of short papillae on the radial parastigmatic vessels. Similar papillae occur only in the recently described Molguloides sulcatus Sanamyan and Sanamyan, 1999.

Originally described from the Guinea Basin, the species was then recorded from the south Atlantic, south-east Paci®c Basin, Macquarie Island and the south Indian Ocean.
