Remarks. Munidopsis curvirostra belongs to the group of species with the carapace lateral margin with an anterolateral spine only, two epigastric spines and a row of spines in the dorsal midline, the rostrum spiniform being more than twothirds as long as the remainder of the carapace and strongly upcurved, the front margin without antennal spine, abdominal segments 2 and3 with median spine, segment 4 unarmed; the cornea oval, about half or slightly more than half the length of the ocular peduncle, the eyespine absent, the first walking leg not reaching end of the cheliped, the merus of the cheliped lacking spines, other than distal spines, the meri of the walking legs relatively slender, not keeled dorsally, and epipods absent from pereiopods. The species is very close to M. acuta (A. Milne Edwards, 1881) from the Bay of Biscay, and M. longirostris (A. Milne Edwards & Bouvier, 1897) from Morocco, respectively. These two species are considered to be junior synonyms of M. curvirostra (Hansen 1908, see A. Milne Edwards 1883, edition of 1997). However, a complete revision of the type material of these species would be desirable in order to confirm the existence of one or several taxa (Udeken d’Acoz 1999). Distribution. Northwest Atlantic, Gulf of St Lawrence, 146–403 m (type locality, Whiteaves 1874, see also Smith 1886, Squires 1990), Davis Straits, Iceland, 349–975 m (Hansen 1908), Ireland, 1797 m (Selbie 1914), S of Greenland (Heegaard 1941), southeast of Newfoundland, 1100 m (Sivertsen & Holthuis 1956), Portugal and Morocco, 1716–1912 m (Türkay 1976), Middle Atlantic Bight, 636–2200 m (Wenner 1982), Bay of Biscay, 1845–2430 m (de Saint Laurent 1985); British Isles (Moyse & Smaldon 1990), Morocco (GarciaRaso 1996). The species has been also cited at the Lord Howe Ridge, southwest Pacific, at 1210 m (Khodkina 1981). The present material has been collected in the northeast Atlantic, from Ireland (57º59’N) to Mauritania (20º30’N), between 1010 and 2114 m.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
