vesicula seminalis having become by this time greatly swollen 

 on account of the contained male products. The latter is an 

 elongate bent organ lying in front of the ovary and passing 

 laterally round and above the inner portion of the cirrus sac and 

 coming to lie dorsally to and sometimes in front of it. It event- 

 ually opens into the sac, its inner portion being slightly coiled. 

 An inner vesicula was not seen. The cirrus is relatively very 

 long (043 to 0'52 mm.) and thin (O'OOS mm. broad), its muscular 

 walls being covered with a dense armature of very fine bristles 

 like those of the accessory sac. The cirrus sac is an elongate 

 organ about 056 mm. in length and 0'087 mm. in maximum 

 breadth tapering somewhat laterally, lying in the anterior 

 portion of the segment. Its walls contain a well-developed 

 musculature. The sac passe* inwards dorsally above the excret- 

 ory vessels and then bends ventrally so that its inner end lies 

 below the vesicula seminalis. 



The female glands lie between the testes but the specimens 

 are so poorly preserved that very little detail can be made out. 

 The ovary appears to be a small bilobed organ lying just behind 

 the middle of the proglottis and just anteriorly to the two 

 posterior testes. The vitellarium, a rounded compact gland, lies 

 postero-ventrally to the short ovarian bridge, tlie shell gland 

 being situated antero-dorsally to the yolk gland and postero- 

 dorsallv to the ovary. The uterus is seen to be a transverse tube 

 which later becomes more or less sac-like. Ripe eggs were 

 not present. 



The vagina passes inwards from the female pore for a short 

 distance as a wide thin-walled duct. It then becomes narrowed 

 to travel as a thin and very definite tube in a more or less 

 sinuous course dorsally forwards anil inwards above the cirrus 

 sac. Its walls are covered with very minute bristles. Just 

 in front of the sac. it enters the relatively large thin-walled 

 spindle-shaped receptaculum seminis. The latter passes back- 

 wards below the cirrus sac and becomes narrowed to form the 

 short fertilising duct in front of the ovary. 



In spite of the incompleteness of the above description, it will 

 be seen that there can be no doubt as to the identity of Kreflft's 

 species with Hymenolepiti sinuosa, Zeder, or more correctly
