Mr. Tristram notes his sucessful acclimatization in Durham 

 of Helix villosa from Switzerland ; of Parmacella near Newcastle, 

 of H. lapicida from the South of England on the banks of the 

 Wear. African and Syrian Clausilms, and Syrian Helices turned 

 out in Durham have not been able to stand the cold of winter. 

 The ova of freshwater mollusca are often transported on the feet

 mollusk — probably Succinea.
