Plerocercoids of Bothriocephalite living between the tissues 

 and organs of various vertebrate animals ; the adult stage to 

 which they give rise is unknown, and they cannot therefore be 

 assigned to a definite genus. These plerocercoids were discovered 

 in 1882 by P. Manson during the post mortem on 

 a Chinaman who had died in Amoy, twelve speci- 

 mens being found beneath the peritoneum and one 

 free in the abdominal cavity. Cobbold described 

 them as Ligula mansoni, and Leuckart, who con- 

 temporaneously reported a case in Japan, termed 

 them Bothriocephalus liguloides. Ijima and Murata 

 reported eight further cases. 



The plerocercoid, which hitherto alone is known 



1* IG. 149- 



Cephalic end of to us, attains a length of 30 cm. and a breadth of 



3 _6_i2 mm. The ribbon-shaped body is wrinkled, 

 Leuckart.) the lateral borders are often somewhat thickened, 



so that the transverse section has the form of a 

 biscuit ; the anterior end is usually wider and carries a retractile 

 head, provided with two weak suctorial grooves. 



The parasite makes migrations within the body, and thus may 

 reach the urinary passages ; then it is either evacuated with the 

 urine or has to be removed from the urethra ; not rarely it 

 causes excrescences on various parts of the skin, when this takes 

 place it has to be removed by an operation. 



Nothing is known of its development and origin.
