Voragonema laciniata – Lindsay & Pagès 2010: 36–37. Remarks According to Haeckel (1879, 1881a, 1881b), Pectis antarctica is a hydromedusa exhibiting the following characters: 1) bell nearly hemispherical; 2) exumbrella Fnely ribbed radially; 3) mesoglea moderately thick in the upper half, and comparatively thinner in the lower half; 4) eight radial canals connecting with the ring canal, the latter giving rise to 11–13 centripetal canals in each octant; 5) eight ovoid, convoluted gonads, extending along the proximal half of the radial canals; 6) a quadrangular manubrium provided with 8 pairs of outer, hollow, hemispherical pouches; 7) a strong, muscular velum; 8) a great number of solid marginal tentacles not arising in distinct clusters, but showing a certain regularity in their arrangement around the bell margin; 9) a continuous ring of nematocysts between the velum and the lowest row of tentacles; 10) the occurrence of a number of free, small, club-shaped statocysts with single, spherical statoliths. In light of these characters, especially the presence of centripetal canals, also found in Ptychogastria polaris Allman, 1878, Maas (1906a) transferred Haeckel’s species to the genus Ptychogastria Allman, 1878. He acknowledged only “relative” differences in the arrangement of the marginal tentacles, and noted a remarkable reduction of the “mesenteries” (sic!) compared to both Pt. polaris and Pt. asteroides (Haeckel, 1879).
