The throat musculature shows some similarities in Shinisaurus and Xenosaurus which might be indicative of a relationship of the two genera. The single interdigitating portion of the intermandibularis anterior separates a wide mesial from a narrower lateral portion of the geniohyoideus, a marked contrast to the Anguidae, and the genioglossus lateralis and medialis are of equal strength. No genioglossus lateralis fibres reach the hypobranchial skeleton in Shinisaurus.
