AMPHIMERUS 



257 



o.s. 



-Wb. 



A-4....ac, 



Testes. Anterior testis 0*496 by 0*44 mm. ; posterior testis 0*52 by 

 0*48 mm., usually ovoid, though both may be regularly lobed. The 

 anterior testis is usually on the left side. 



Ovary multilobular, the lobes 6 to 8 being irregular in size and 

 shape. 



Shell Gland extensive and diffuse, occupying an area which approx- 

 imately corresponds with the loop of the transverse vitelline ducts. 



Seminal Receptacle globular, to the right of and dorsal to the 

 posterior lobe of the ovary. 



Lanrer's Canal generally 

 runs from the end of the re- 

 ceptacle with a single curve 

 medially and backwards. 



Uterine Coils form loosely 

 packed transverse coils ter- 

 minating slightly in front of 

 the level of the first vitelline 

 acini. From here the uterus 

 passes forwards into the pedicle 

 to the left and ventral to the 

 seminal vesicle. 



Seminal Vesicle com- 

 mences about the level of the 

 first vitelline acini. The coils 

 displace the uterus ventrally and 

 to the left. In the pedicle the 

 vesicle diminishes in extent and 

 lies in its dorsal (anterior) side. 



Habitat. -Liver of pariah 

 dogs, India. In North- Western 

 Provinces about 40 per cent, 

 are infected. This fluke ap- 

 pears to be different from 

 Amphimerus (Opisth orchis) 

 noverca in man, as the latter has 

 not the pedicle on the summit 

 of which lie the sucker and 

 common genital pore. 



Genus. Amphimerus, Barker, 



1912 (?). 



Structure as in Opisthorchis, ex- 

 cept that the vitellaria are separated 

 into two portions, an ant-ovarial and 

 a post-ovarial.
