Totton, 1932
Small pyramidal anterior nectophores, generally ridged, the number and disposition of the ridges being variable. Small, divided mouth plate, with shallow hydroecium, rarely extending above ostial level. No ostial teeth. Posterior nectophore, when developed, truncated apically with a rounded mouth plate. Bracts helmet-shaped. Shape of phyllocyst generally resembling that of somatocyst of anterior nectophore. This is a catch-all genus, containing over thirty species that do not show the distinctive characters of the other genera. The species are here grouped according to whether they have 7 or less ridges (1 dorsal, 2 ventral and 0, 2 or 4 laterals), all running longitudinally, or they are multi-ridged.
