Discovery reports (1956) Discovery reports discoveryreports27inst Year: 1956 Figs. 21-26. Trigonocotyle globicephalae from Globicephala edwardi. 21, scolex in lateral view; 22, cross-section through mature segment in anterior cylindrical part of strobila; 23, cross-section through segment in flattened part of strobila, showing cirrus- sac, vagina and longitudinal muscles; 24, cross-section through mature segment in anterior cylindrical part of strobila showing longitudinal muscles; 25, cross-section through gravid, flattened part of strobila showing longitudinal muscles; 26, egg. The length of the body in the specimens examined is about 21 cm. The strobila appears to be divided into two portions; the anterior part is cylindrical and about 2 cm. in length, composed of very short segments, while the rest of the body is flattened. It seems that the anterior portion, which bears a resemblance to the cylindrical strobila in Tetrabothriiis affinis, contains mature segments and the flattened part gravid segments with eggs. The scolex, 1-5 mm. broad is provided with four suckers, bearing fleshy protuberances in the form of horns.
