. Discovery reports. Discovery (Ship); Scientific expeditions; Ocean; Antarctica; Falkland Islands. DESCRIPTION OF SPECIES H3 Gonads. The form of the gonads is not exactly that described by Hartmeyer (1912), who stated that the testis follicles are arranged in a complete ring round the ovary. Instead I find that the testis follicles (Text-fig. 64, t) are generally confined to the dorsal side and the anterior end of the ovary (ov.). In some specimens the oviduct is simple, short and terminal, but in a few of those from South Georgia it is branched in an antler-like fashion (od.). I do not know

The male openings are on about five small sperm ducts () arranged along the dorsal margin of the gonad. Distribution. Antarctic (Kerguelen, South Georgia), Subantarctic (off coast of Argentina). mm. Text-fig. 65. Eugyra brewinae (St. 936): A, specimen with test removed; B, oral tentacle; C, dorsal tubercle and ganglion; D, part of branchial wall; E, gonad. Eugyra brewinae (Text-fig. 65) Holotype. Size: 5 mm. diameter. Diagnosis of species. Body small and covered with sand. Test and body wall very thin and trans- parent. Dorsal tubercle a simple longitudinal slit. Branchial sac with six longitudinal bars on each side. Stigmata in regular double spirals. Gonad on left side only, within primary intestinal loop, consisting of central ovary and radially arranged, branched testis-lobes.
