Bibliographic record
Abstract
** Camallanus oxycephalus Ward & Magath, 1917 Description (after Stromberg et al. 1973). With characteristics of the genus. Slender worms, widest in middle third of body and tapering slightly towards tail. Living worms red in colour. Cuticle with barely perceptible striae. Head straight, not bent ventrally. Mouth opening elongate. Buccal capsule divided into two sclerotized lateral valves with smooth longitudinal rib-like thickenings internally; inflation of valves forms sclerotized ring at junction of buccal cavity and oesophagus. Two trident-shaped processes at junction of valves, one dorsal, one ventral (Fig. 40 A). Three pairs of simple circumoral papillae in outer circle; two pairs in inner circle at dorsal and ventral ends of mouth opening. Oesophagus with anterior club-shaped muscular portion, and posterior cylindrical glandular portion. Intestine straight. Anal lips slightly protruding. Males: 4.57 (4.43–5.20) long; width 0.15 (0.12–0.18). Buccal capsule 0.103 (0.096–0.112) by 0.100 (0.096– 0.107). Tridents 0.094 (0.086–0.104) long. Muscular oesophagus 0.390 (0.360–0.422), and glandular oesophagus 0.461 (0.428–0.530) long. Nerve ring 0.168–0.210 from anterior end. Single testis reaching almost to glandular oesophagus, then reflexed; reproductive tract with several swollen portions separated by constrictions. Tail 0.121 (0.109–0.136) long, rolled ventrally in mature worms, ending bluntly without a mucron. Thin caudal alae supported by papillae. Six pairs pre-cloacal, five pairs post-cloacal papillae. Spicules unequal but similar, left one weakly sclerotized, right one heavily so, 0.154 (0.146–0.166) long. Gubernaculum absent (Fig. 40 B). Females: 18.18 (15.93–25.05) long. Buccal capsule 0.137 (0.128–0.142) by 0.151 (0.136–0.165). Tridents 0.138 (0.134–0.144) long. Muscular oesophagus 0.569 (0.483–0.666), glandular oesophagus 0.652 (0.558–0.748) long. Nerve ring 0.262 (0.222–0.300) from anterior end. Vulva 2.24–3.11 from tail tip, lips slightly protruding. Vagina very muscular, directed posteriorly. Single ovary reaching level of muscular oesophagus, then reflexing; posterior branch of uterus reaching tail end, ending blindly in an highly muscular sac. Tail 1.87 (1.53–2.21) long, bluntly rounded without mucron (Fig. 40 C). Ovoviviparous: larvae 0.635 (0.629–0.645) long.

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.
