of animals and were found in ten per cent of the stomachs 
examined. In a few stomachs, the digestive fluids had dis¬ 
solved the shell beyond recognition. The species that could 
be identified were: 
Limacida .3 
Zonitoides arboreus Say.3 
Strepomatidce .5 
Goniobasis informis Lea.5 
Limneaidce .11 
Galba humilis modicella Lea.4 
Physa heterostropha Say.7
