hardest part of the body of the oyster, is, after being attacked by 
the Wafer, quite soft, though smelling quite fresh. 
One aspect of the case which is very puzzling is, as to how the 
worm gains entry between the shells of the oyster without the latter 
“closing down’’ on it; as, if it did, the Wafer would surely be 
nipped in two. 
I must here mention that the fact of the Wafer preying upon the 
oyster—although hitherto unrecorded—cannot be looked upon as 
very startling, as some allied fresh-water forms in Europe are 
known to prey upon pond snails, crustaceans, water beetles, &e. 
In conclusion, I would like to point out that any information 
which can be given by any of our oyster farmers, in regard to the 
occurrence or habits of the Wafer in their respective waters, will 
be of the greatest value, and will assist in enlarging our knowledge 
of what might at any time prove to be a serious scourge.
