Caryophyllaeus — C. filiformis. The chief character- 

 istics of the new genus are the situation of the sexual apertures 

 in the anterior half of the body, and the elongated uterus. 

 The family Caryophyllaeidae, after deletion of the 

 genera D i p o r u s , M o n o b o t h r i u m , and G 1 a r i d a c r i s , 

 thus contains three genera — Caryophyllaeus, Archi- 

 getes, and Wenyonia — all of which are re-defined, with 

 their known species. 



2. Very young immature forms of Wenyonia occur in the 

 same (Siluroid) host as the adult and are devoid of a ' caudal ' 

 appendage, whence it would appear that the life-history of 

 these new forms is different from that of C . 1 a t i c e p s . 



3. The three families of the Cestodaria — Caryophyl- 

 laeidae, Gyrocotylidae, and Amphilinidae — are 

 re- defined. 



4. The Cestodaria, after eliminating Sanguinicola 

 (a Trematode ?), are provisionally grouped into two Orders : 

 the Amphilinidea (with one family, the Amphilinidae) 

 and the Paralinidea (with two families, the Caryophyl- 

 laeidae and the 6 y r o c o t y 1 i d a e), the latter being closely 

 allied to the Bothriocephalidae. These two Orders are 

 defined.
