TWO NEW PARASITIC FLATWORMS 



By Marion Elizabeth Lamont 

 Zoological Laboratory, University of Wisconsin 



In studying the parasites of Wisconsin fishes two new species 

 have been discovered — a primitive tapeworm and a trematode. 

 These are described in this paper. 



Carophyllaeus 0. F. Miiller 



Characteristics of genus: The representatives of this genus, 

 like other Cestodaria, resemble trematodes in being without pro- 

 glottids and are like cestodes in lacking an enteron. They are 

 elongated, flattened, and possess a primitive scolex. A caudal 

 appendix is present in larval forms but is lacking in adults. The 

 genital pore is ventral, median, and near the posterior end. The 

 uterus is made up of rosette-shaped coils and opens with the vagina 

 into a genital atrium. 



Liihe (1899) classifies the Carophyllidae as the first family 

 under the order Pseudophyllidea. Other authors (Ward and 

 Whipple, 1918, p. 429) put them in the subclass Cestodaria as 

 distinct from the Cestoda.
