Field Notes - I don't know a lot about snails . I was removing weeds when I found this snail hidden under grass in the bushland near Bourke street , North Parramatta. Diameter about of 2-3cm.
Many on the river walk after heavy storm rains. Mostly 1cm or smaller.
Appears to be some form of saddled riding snail.
Army ants have had reforms, they now have cavalry.
