Cyclocaris faroensis Norman, 1900: 197–198, pl. 6, figs 5–15.— Thurston & Allen, 1969: 358. Remarks. This species differs from all others in the genus by the permanent yellow-brown ocular pigment covering the whole surface of the head. The absence of eyelobes separates it from C. lowryi and C. franki. The comparison is based on Barnard (1959), the best available account of the species. C.guilelmi is a well known Arctic species. It occurs widely at mesopelagic and bathypelagic depths, mostly at 500-2000+m (Stephensen, 1923, Østvedt, 1955, Birstein & Vinogradov, 1958, 1970), but has been recorded in the epipelagic zone (Sars, 1900, Stephensen, 1933). The species is attracted to sediment traps in large numbers (Seiler & Brandt, 1997, Kraft et al. 2013) and has been taken occasionally in baited traps, both benthic, at 1095 m (Chevreux, 1899, 1935), and midwater, at 1800 m (Barnard, 1959). The species appears to breed throughout the year (Kraft et al. 2013). Distribution. Disjunct: Arctic Ocean, north-west Pacific Ocean. Norwegian Sea, Greenland Sea, south to the Faroe-Shetland Channel (Norman, 1900, Stephensen, 1923, Østvedt, 1955, Seiler & Brandt, 1997, Vinogradov, 1997, Kraft et al. 2013); Baffin Bay (Stephensen, 1933, Buchanan & Sekerak, 1982); Arctic Ocean, Nansen, Amundsen, Makarov and Canadian Basins (Sars, 1900, Barnard, 1959, Kosobokova et al., 2011); Pacific Ocean north of 39˚N and west of 170˚E (Birstein & Vinogradov, 1955, 1958, 1970).

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.
