minute and completely ventral, opening of the posterior sucker very 
wide, transversely oval, about 2 mm. in its largest diameter The 
same is the average distance between the centres of the two sucken 
In some cases the part of the body containing the anterior sucker was 
found separated from the rest in the shape of a minute but quite 
distinct cone resembling that which characterises the members of the 
genus hasciola. Immediately in front of the ventral sucker there b 
a transverse slit indicating the position of the genital aperture All 
round the margin of the body, the colour of the worms is considerably 
duller than in the middle and in most cases this duller tint 
projects twice on each side in an angular fashion into the lighter 
1 entral area, this latter thereby assuming the shape of three 
successive but incompletely separated discs. All these charaders 
discernible by naked eye inspection suggested Fasciolofsis bush 
(Lank ). A comparison of the internal organisation so far as this 
could be made out from cleared entire individuals did not reveal any 
noticeable difference from the description recently given of the species 
\\ Odhner (1902). The determination Distoma crassum is therefore 
coirect, for the name Distoma crassum (COBB), 1877. is only a 
synonym of Fasciolopsis buski (Lank). 1857.
