Abstract
Tetranema furcata Fraser, 1937a Tetranema furcata Fraser, 1937a: 193, pl. 44, figs. 233a–e. Astrolabia furcata.— Schuchert, 1997: 151. Syntypes. BCPM 976-00948-001: Canada, British Columbia, Queen Charlotte Islands (=Haida Gwaii), Moresby Island, Kaison Bank, 28 July 1936, 201 m, two colonies, labelled "type"; 60% IPA. BCPM 976-00948-002: Canada, British Columbia, Queen Charlotte Islands (= Haida Gwaii), Moresby Island, Kaison Bank, 28 July 1936, one colony; slide. Lectotype, by present designation. RBCM 976-00948-003: Canada, British Columbia, Queen Charlotte Islands (= Haida Gwaii), Moresby Island, Kaison Bank, 201 m, 28 July 1936, one colony, 3.3 cm high, with one gonotheca, in good condition; 70% ethanol. Paralectotypes. BCPM 976-00948-001: Canada, British Columbia, Queen Charlotte Islands (=Haida Gwaii), Moresby Island, Kaison Bank, 201 m, 28 July 1936, one colony, 2.1 cm high, without gonothecae, in fair condition; labelled "type"; 60% IPA. BCPM 976-00948-002: Canada, British Columbia, Queen Charlotte Islands (= Haida Gwaii), Moresby Island, Kaison Bank, 28 July 1936, one colony, 1.3 cm high, with one gonotheca, in good condition; slide. Type locality. Canada, British Columbia: Queen Charlotte Islands (= Haida Gwaii), west coast of Moresby Island, Kaison Bank (Fraser 1937a). Current status. Valid, as Astrolabia furcata (Fraser, 1937a). Remarks. Although Fraser (1937a) designated no name-bearing type for Tetranema furcata, syntype material of the species exists at the RBCM. Two colonies were represented in fluid (BCPM 976-00948-001), with the larger one, in better condition and with a gonotheca, being designated here as the lectotype of the species. It was removed to a new bottle and assigned a new catalogue number (RBCM 976-00948-003). The smaller colony, sterile and in poorer condition, was returned to the original bottle as a paralectotype (BCPM 976-00948-001). A second paralectotype specimen occurs on a microscope slide (BCPM 976-00948-002). Although the slide is broken lateral to the mount, the hydroid colony is in good condition and bears a gonotheca. The original description of Tetranema furcata by Fraser (1937a) included accounts of both its trophosome and gonosome. With Tetranema Fraser, 1937a being an invalid junior homonym of Tetranema Haeckel, 1879, the specific name is now combined with a subjective synonym, Astrolabia Naumov, 1955, as A. furcata. The hydroid is reportedly amphi-Pacific in distribution, with A. heterotheca Naumov, 1955 from a depth of 576 m near Astrolabe Strait, Kuril Islands, Russia, being a subjective junior synonym (Antsulevich 2015).

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.
