In describing Meganema claviformis, Fraser (1939b) reported that the hydroid was “attached to sponges, barnacle shells, etc.” No name-bearing type was designated by him. The only type material of the species in existence is mounted on a slide (BCPM 976-00302-001) in the Fraser Hydroid Collection at the RBCM. Two specimens occur on the slide, both of them fragmentary. While the fragments may be part of a single colony, we have not assumed so for nomenclatural purposes (ICZN Recommendation 73F). The specimen on the left side of the slide has been designated here as the lectotype (RBCM 976-00302-002) to objectively define the species and ensure stability of nomenclature. The specimen on the right is the paralectotype. Fraser (1947a) abandoned Meganema Fraser, 1939b as valid, acknowledging that M. claviformis was referable to the same genus as Lafoeina maxima Levinsen, 1893. He nevertheless persisted in recognizing Lafoeina claviformis as a distinct species. The two were later regarded as synonyms (Calder 1970, 1991). The species is listed in Cairns et al. (2002) as Keratosum maximum and in WoRMS as Lafoeina maxima. The former is maintained here for reasons given above in Remarks on the genus Meganema.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
