Abstract
Serpula columbiana Johnson, 1901 Figs 9 A–B, 10 Serpula columbiana Johnson, 1901: 432–433, pl. 19, figs 199–204 (type locality: Alki Point, Puget Sound, Washington, United States). Serpula splendens Bush, 1905: 230–232, pl. 26, fig. 3, pl. 29, fig. 2, pl. 30, figs 2–3, pl. 33, fig. 31, pl. 35, fig. 18, pl. 37, fig. 31, pl. 39, fig. 33 (type locality: Orca and Virgin Bay, Prince William Sound, southern Alaska). Serpula nannoides Chamberlin, 1919b: 270, pl. 2, fig. 8 (type locality: off Crescent City, California). Serpula vermicularis (non Linnaeus 1767) – Chamberlin 1919b: 269 (Mendocino, northern California and Gulf of Georgia (Strait of Georgia), Washington). — Berkeley 1930: 73 (Nanaimo Region). — Berkeley & Berkeley 1941: 55 (Santa Cruz Island, southern California). — Hartman 1948: 47 (Seldovia, Alaska). — Kupriyanova 1999: 24 (synonymy). Serpula columbiana – Pixell 1912: 784–786 (Departure Bay, Canada and Puget Sound, Washington; undersides of stones on rocky shores and in rock pools). — Treadwell 1914: 225 (Puget Sound, Washington, to San Diego, southern California). — Kupriyanova 1999: 24–27, figs 1, 3, 4B, D (Alaska, Washington and California). — Bastida-Zavala 2008: 45–46, figs 11A–E (Washington and California; 30–60 m; on bottoms with coralline sand and kelp, on shells, cobble and boulders). Serpula splendens – Kupriyanova 1999: 24 (synonymy). Serpula nannoides – Bastida-Zavala 2008: 45 (synonymy). Material examined One specimen: KT (1) Sep. 2003. Diagnosis Tube missing.Opercular peduncle smooth, white, with marked constriction.Operculum funnel symmetric, with 46 radii with blunt tips, and concave inner surface, with numerous tiny conical tubercles (Fig. 9A). Collar with bayonet chaetae, with two blunt, short teeth, smooth distal blade. In adult forms, Serpula columbiana has an operculum with 55–160 radii (Fig. 9B) and a symmetric funnel (Kupriyanova 1999). Taxonomic remarks The status of Serpula columbiana was resolved by Kupriyanova (1999). It is mainly a sublittoral species that is extremely unlikely to belong to the fouling fauna. Ecology Intertidal to 60 m. Under stones on the shore-line, in rock-pools (Pixell 1912), and on bottoms with coralline sand and kelp, on shells, cobble and boulders (Bastida-Zavala 2008). Distribution Northeastern Pacific, from Alaska to southern California (San Diego) (Kupriyanova 1999; Bastida-Zavala 2008). In this work, only one specimen of Serpula columbiana was found on a fouling plate from Ketchikan Bay, Alaska (Fig. 10).

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.
