 lina and the other to Peltogaster. The examination of these new 

 materials gave rise to the paper of which the following is an 

 abstract. 



Liriope, Rathke. 



The specimen measured 2^ millim. across. The whole anterior 

 part of the Liriope (see vol. vi. PI. 4. figs. 2 & 3 a) had penetrated

 from the outside. The part of the Peltogaster to which the 

 Liriope was attached was swelled. The Peltogaster contained no 

 eggs. The body of the Liriope was more distended than that 

 before described, and exhibited no folds or wrinkles. Its form
