The problems of resolving historical specimen data, focusing on a specimen of <i>Myotis austroriparius</i> (Mammalia, Chiroptera, Vespertilionidae) collected by Thomas Drummond
Bibliographic record
Abstract
The geographical itineraries of Thomas Drummond’s two separate expeditions to Canada (1825–1827) and the United States of America (1831–1835) are used to provide historical context for the specimens collected and their localities. The coordinates for these locations are estimated and their geographical positions mapped. The difficulties of resolving various problems with historical specimens are explored and several examples are provided, including the contentious origin and identification of a southeastern myotis, Myotis austroriparius (Rhoads, 1897) (NHMUK 1837.4.8.127). Information about type specimens is discussed and the geographical position of several type localities of rodents and a mustelid in the Rocky Mountains and a lagomorph in the USA are refined.
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.
