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 Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Institute of Oceanographic Sciences (Great Britain); National Institute of Oceanography of Great Britain; Great Britain.
