The sub-family Nectopyramidinae (Siphonophora, Prayidae) is reviewed and revised. Previously the sub-family was considered to comprise one genus, Nectopyramis, with four species. However, it is shown that the two types of nectophore previously ascribed to N. spinosa are actually the larval nectophores of two other species, namely N. thelis and N. natans. A new genus Nectadamas gen. nov. is erected to include the other species, diomedeae. The differences between the two genera are principally the arrangement of the radial canals to the nectosac and the shape of the hydroecium in the definitive nectophore; and the presence or absence of a special nectophore. A new species Nectadamas richardi sp. nov. is described, the eudoxid of which previously had been ascribed to N. spinosa.
