Abstract
The freshwater leeches (Hirudinida) in the Province of Newfoundland and Labrador were investigated by examining theliterature, the Canadian Museum of Nature and the United States National Museum of Natural History records, and aleech survey. New pigmentation forms are described for Erpobdella punctata (Leidy) and Erpobdella obscura (Verrill).This is the first published record for Haemopis lateromaculata Mathers in Canada. Four species (Glossiphonia elegans(Verrill), Helobdella modesta (Verrill), Erpobdella punctata, and Erpobdella obscura) were found in both Labrador andNewfoundland with Erpobdella obscura common in Labrador and the other three species common in Newfoundland.Seven other species of leeches were less abundant in Newfoundland with 6 of these species very restricted in distribution.The abundance of leech species in Newfoundland and the paucity of leech species in Labrador suggested that theisland species were present in a Pleistocene refugium associated with Newfoundland or the Grand Banks. Post-Pleistocenebarriers to leech mobility are examined, and possible timing of colonization events is proposed in this model.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
