Anguidae View in CoL View at ENA ( Fig. 14U–Z)

Anguids have a subtriangular orbitonasal flange projection, which is wider but very slightly shorter than the slender and truncated posteroventral process ( Fig. 14V, Y). There is no ornamentation in Anguis gr. An. fragilis ( Fig. 14U), whereas very mild rugosities are visible dorsally in Pseudopus apodus at the base of the dorsal process ( Fig. 14X). A distinct posterolateral projection is absent and the notch for the lacrimal foramen is wide and moderately ( Anguis gr. An. fragilis ; Fig. 14U–W), or very, deep ( Pseudopus apodus ; Fig. 14X–Z). The dorsal process is slender and moderately long, being as long as, or slightly longer than, the rest of the prefrontal in lateral view.The palpebral crest is low; in adults of Anguis gr. An. fragilis it is not clearly recognizable.

JUGAL

Jugals ( Fig. 16) are curved and paired bones, roughly L-shaped in lateral view, with an anterior and a posterodorsal process. The anterior process can have a medially developed shelf, the palatal process, whose posterior end can develop a triangular medial process of the jugal. Between the anterior and the posterodorsal processes, a quadratojugal process can develop in ventral direction. A row of small foramina pierces the lateral surface of the bone.
