Abstract
Halicornaria indivisa Fraser, 1936c Halicornaria indivisa Fraser, 1936c: 52, figs. 7a–d. Haliaria indivisa.— Yamada, 1959: 83. Gymnangium indivisum.— Vervoort & Watson, 2003: 286. Syntype. BCPM 976-00857-001: Japan, Sagami Bay; slide. Lectotype, by present designation. BCPM 976-00857-001: Japan, Sagami Bay, one colony fragment, 1.2 cm high, in good condition, with gonophores; slide. Type locality. Japan: Sagami Bay, 90 m (Fraser 1936c). Current status. Valid, as Gymnangium indivisum (Fraser, 1936c). Remarks. Fraser (1936c) described Halicornaria indivisa from hydroids obtained by Emperor Hirohito at a depth of 90 m in Sagami Bay, Japan. No name-bearing types were designated by him in the original account of the species. Fraser described H. indivisa as “Colony large, 25 cm. in length…”, but the only specimen of the species in the Fraser Hydroid Collection at the RBCM (BCPM 976-00857-001) is a small fragment of a colony on a microscope slide. We nevertheless conclude that it is a type, possibly a fragment of the large colony described by Fraser. Rather than assume that it is the holotype by monotypy, however, we have designated the specimen as the lectotype of H. indivisa (ICZN Recommendation 73F). Records of three collections of this species (as Haliaria indivisa) in the Emperor Shōwa Hydroid Collection at NMNS (NSMT-HyR 1424–NSMT-HyR 1426) generally correspond with Fraser’s distribution data. Others (NSMT-HyR 1427–NSMT-HyR 1443) were obtained either at different depths or were collected after Fraser’s manuscript was presented at a meeting of the Royal Society of Canada in May, 1936. This hydroid, now known as Gymnangium indivisum, is regarded as a valid species in WoRMS. The colony, described as robust and unbranched, attained a height of 25 cm. Better illustrations than those in Fraser (1936c) are provided by Hirohito (1995, as Haliaria indivisa).

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.
