These species of Polygyra are distinguishable by the presence of characteristic "teeth" in the entrance of the shells. The large spider (Dolomedes tenebrosus) and millipede (Spirobolus marginatus) occur. Crane-fly larvae, ground beetles (Plerostichus adoxus), a centipede (Geophilus rubens), the wood- frog {Rana syhatica) (Fig. 241) (139), and the red-backed salamander {Plethodon cinereus) (152) (Fig. 242) are common and Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Shelford, Victor E.
