Abstract
Family Acaulidae Fraser, 1924b Acaulidae Fraser, 1924b: 173. Current status. Valid. Remarks. Stimpson (1853) described and illustrated Acaulis primarius, a remarkable new genus and species of solitary hydroid from Grand Manan Island, New Brunswick, Atlantic Canada. His polyp was unusual in having a very short, spike-shaped hydrocaulus beneath a large hydranth having scattered capitate tentacles and an irregular whorl of filiform tentacles at the base. Some early authors (e.g., Allman 1872) believed Stimpson’s hydroid constituted a hydranth that had detached from its stalk. Even though G.O. Sars (1874) subsequently described and accurately illustrated A. primarius from Lofoten, Norway, uncertainty persisted over the morphological structure of the species (e.g., Fewkes 1890; Dendy 1902; Fraser 1918c). Fraser (1924b) confirmed the morphology of its hydrocaulus, and established the family Acaulidae to accommodate the species. The taxonomy of A. primarius has recently been reviewed by Schuchert (2006). As noted therein, two species were mistakenly included under that binomen by Stimpson (1853). However, Schuchert concluded that Allman (1872), in effect, had designated a lectotype (ICZN 74.5) by fixing its identity in conformity with that matching the longstanding concept of the species. That concept accords with the only illustration of A. primarius provided by Stimpson (1853, pl. 1, fig. 4). Type material of the species exists at the MCZ (Invertebrate Zoology Coel-162).

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.
