Median branch of tridents — mm long. Muscular part of esophagus — mm long, glandular part mm. The development of ? amallanus truncatus was studied by Kupriyanova (1954). The females are viviparous. Larvae discharged into the water with the feces of fish are colorless, — 0,430 mm long, and — mm wide. There is no chitinized buccal capsule and the intestinal tract is weakly developed and not differentiated. The tail is long and pointed. Larvae of C. truncatus survive 11—12 days in water at 9—10°.. FIGURE 41. Camallanus truncatus (Rudolphi, 1814): a — cephalic end, ventral; b — same, lateral; ? — larva from an adult female (a, b — after Meszaros, 1967; ? — after Kupriyanova, 1954). At 18—20°, larvae swallowed by Cyclops enter the body cavity after 40 minutes. At 19—21°, larvae of C. truncatus undergo the first molt in'Cyclops after 24—48 hours. The old cuticle is very thin and adheres closely to the new one. Second-stage larvae are — mm long and mm wide. The caudal end becomes more rounded. The second molt takes place after 5—6 days. The larvae now have a distinctly chitinized buccal capsule, but tridents are still absent, and they are probably not developed at all in larvae in Cyclops, as none were observed even after 32 days in the host. The esophagus is divided into a muscular and a glandular part. The caudal end becomes much shorter and the larvae turn yellowish. Length — mm, width mm. If the temperature fa
