Remarks. Oswaldella elongata is an uncommon species, well characterized by the long hydrothecae, the absence of mesial inferior nematothecae in the hydrocladial internodes, the presence of two axillary nematophores and two ‘mamelons’ in the cauline apophyses and the presence of only secondary hydrocladia (cf. table 1).

Ecology and distribution. Oswaldella elongata is known only from off Clerke Rocks and South Georgia, where it was found between 86 and 250 m depth, growing on hydrocorals (Peña Cantero et al., 1995) .
