pica (not a rodent but a rabbit relative if i remember right, but real ones don't have electric tails)
reticulated ground squirrel (never saw or heard of them before i moved to where i am now, but they're quite common here. quail were quite common where i grew up)
unicorn, checkered (acanthina paucilirata) size 1/3 to 1/2 inch. shell stoutly fusiformed ... (yes i had to look that up. there are three or four other index entries for the next time around still too)
