nished with one. In our present lecture we shall 
turn our attention to the first of these tribes, or 
Soft- bodied Animals without any truly shelly or 
very hard integument, though some of them, as 
we shall perceive when we arrive at such particu- 
lar genera, have a kind of coriaceous, and even a 
crustaceous covering. In giving a view of the 
Linnaean Mollusca, it is not my intention to pass 
formally through every genus, but to select as ex- 
amples such as are either most important or most 
curious. 
The genus Limax\ which stands first on the. 
list, may be considered as important ^ since it 
forms, as it were, the type or pattern of most of
