draconcopode
Literally "snake-footed", draconcopodes are an apodal creature that moves around by slithering on a snake-like tail or similar. This can describe anything from a snake with a human head to a naga or a lamia. It also covers other slithering bodies that don't fit neatly under either naga or lamia, including "half-feral" types that may use forelimbs when moving.
