Stenostomum virginianum Nuttycombe 1931
Bibliographic record
Abstract
Stenostomum virginianum Nuttycombe, 1931 (Fig. 3F) Stenostomum carnivorum Jones, 1932 Description: Individuals with 1–4 zooids up to 5 mm long, solitary individuals 0.4–1 mm long. Mobile tapering anterior end. Small, rounded ciliated pits lateral or latero-ventrally placed. Truncate caudal end without intestine-lacking region. Vacuolar epidermic cells and short rhabdites. Long semi-rigid cilia concentrated in the anterior and posterior ends of the body. Vacuolar epidermal cells. Colour in life whitish. Anterior brain lobes forming small independent masses (‘metameric’). A pair of light-refracting bodies, with fewer than ten spheres (type 2), associated with an extension of the posterior brain lobes. Small rounded oral pore. Long tubular pharynx (1/4 body length) with isolated pharyngeal glands (type a) distributed along the entire pharynx. Excretophores regularly arranged in two lateral bands, or irregularly in the North American specimens. Nephridiopore subterminal. Distribution: Virginia (Nuttycombe, 1931; Nuttycombe & Waters, 1938), Georgia, North Carolina (Nuttycombe & Waters, 1938; Kolasa, 1991), USA; Nova Scotia, Canada (Jones, 1932); São Paulo State and Paraná State, Brazil (Marcus, 1945b); Los Talas, Berisso, Buenos Aires, Argentina, July 1999. This species has not been previously recorded in Argentina. Stored material: One sagittally sectioned specimen in the CHMLP No. 5307. Discussion: Marcus (1945b) and Luther (1960) refer to the similarity between this species and Stenostomum unicolor O. Schmidt, 1848. The largest sized specimens correspond to those mentioned by Marcus (1945b)

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.
