, on the other hand, the main lateral groove divides the peristomium such that the anterior half laterally and ventrally forms large lateral lips around the mouth and is overlaid with a rounded dorsal crest or dome. The second half of the peristomium, while smooth dorsally, is divided laterally into at least four narrow ridges (
