Fig. 2 is a view of the scolex with the bothria turned 

 to one side so as to expose their sucking' faces. The 

 niyzrtiliynehus is very short and bears no terminal sucker. 

 In all the specimens it is a mere protuberance on the 

 anterior surface of the head. The bothria are four in 

 number, arranged in a cruciform manner, carried on short 

 but very evident pedicels. Each bothrium is oval in 

 shape, and their longest diameters are at right angles to 

 the axes of the pedicels. The sucking face of a bothrium 

 is surrounded by a strong rim or tip which is indented at 

 two places on each margin, and adjoining these indented 

 parts of the rim there are two transverse septa which 

 divide each bothrium up into three separate loculi. The 

 cavities of these loculi are very deep. 



The Neck. 



' This is veiy short. Segmentation almost immediately 



follows the part where the pedicels are inserted. The 

 average distance apart of the segments is about 004 mm., 

 and the edge of the strobila is thus finely and regularly 

 serrated.

 This corresponds very well with that of Antho- 

 hothrium auriculatum (lludolphi), as described by 

 Zschokke. '• The chief dilference is the position of the 

 genital cloaca, which in my specimen is slightly further 

 from the posterior margins of the proglottis than in 

 Zschokke's figures. These openings alternate from side 

 to side of the strobila in a very irregular fashion. The 

 single genital cloaca contains both male and female 

 orifices. The cirrus sac is oval in shape. The vas
