Chinese and is at present the only species of liver fluke known from 
this race. It readies an average size of 18 by 3 5 mm. and has a more 
or less opaque body owing to the presence within the body 
parenchyma of granules of a dark pigment. In Japan, similar flukes 
are also very common in the liver of Man and certain animals; but 
here they vary, especially in size, to such an extent that one of the 
first observers (Baelz) felt justified in establishing two distinct 
species. One of them coincides in size with the Distoma Stnase and 
also possesses the pigment granules in its body parenchyma It is 
in Japan, apparently not very common, for some observers 
subsequent to BAELZ have not come SCTOSS ,1 at all during their 
investigations, whereas Baelz himself considered it as harmless- 
presumably because he never saw it in large numbers -and 
ATSURADa explains the large size of the specimens he saw in 
certain of his cases by the fact of few individuals only being present 
at tie same place. Hie second species is markedly smaller, attaining 
ai average size of n to 12 by 2 mm. only; it is not pigmented and
