Helminths; Worms as carriers of disease. 10—12 (12 in females and 10—12 in males) complete and incomplete longi- tudinal ribs. The ribs are markedly wider anteriorly in females. Tridents yellowish brown, straight, chitinoid, with rounded or blunt posterior ends. They are attached directly to the corners of the valves, dorsal and ventral chitinoid bodies absent.

Tridents yellowish brown, straight, chitinoid, with rounded or blunt posterior ends. They are attached directly to the corners of the valves, dorsal and ventral chitinoid bodies absent. Esophagus divided into a club-shaped mus- cular anterior part and a cylindrical glandular posterior part. The posterior part opens into the intestine through three small nuclear valves. Intestine wider than posterior part of esophagus and with wide lumen. The cells of the intestinal wall are distinct and contain granular protoplasm with small nuclei. Rectum small, opening into the anus in the female and into the clo- aca in the male. Rectum mm long in the female, very narrow. Three nuclear rectal glandular cells at the connection between intestine and FIGURE 32. Camallanus oxycephalus Ward and Magath, 1916: a - anterior end, lateral; b - posterior end of female, lateral (after Tornquist, 1931). Male. Length — mm, width — mm. Dorsoventral width of head — mm. Length of buccal valves — mm, maximum width — mm. Length of tridents — mm. Posterior ring of buccal capsule mm wide. Length of esophagus — mm. Cuticle striated with intervals of — mm. Nerve ring surrounding anterior part of esophagus — mm, the small cervical papillae situated mm, and the excretory pore mm from the cephalic end. Caudal wings well developed. The conical, pointed tail is short, — mm long and is curved ventrally. Caudal papillae large, pedunculate. Five pairs of precloacal and numerous pairs of postcloacal papillae. The first three pairs of precloacal papillae are lateral. T
