Figs. 21-26. Trigonocotyle globicephalae from Globicephala edwardi. 2 1 , 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.
