Opisthorchis sinensis (COBB.) 1875. 
Several worms of a rusty yellow colour contained in a jar of 
unknown origin and labelled “ Distoma stnenst COBBOLD " struck me 
at once by the fact that they were considerably larger and stouter 
than any others I had seen of the species up to that time. I therefore 
had no hesitation in expressing the opinion that these worms could 
not be the true Opisthorchis sinensis. Since the number of specimen; 
was limited, I took two specimens only with me, an unhurt one and 
another which was broken into two pieces. About a fortnight after 
<ny visit to Liverpool I paid a visit to the “Institut fur Schiffs-und 
ropenkrankheiten ” in Hamburg. Dr. hULLEBORN very kindly 
showed me round and, during an inspection of the collection of human 
parasites, 1 was rather surprised to recognise under the designation 
. P lst h° rc his sinensis the same large form which I had seen a short 
c pre\ iously in Liverpool. 1 here were about a dozen individuals,
