Anguidae View in CoL View at ENA ( Fig. 25K–N View Figure 25 )
The general morphology of the septomaxilla of anguids is similar to the one of lacertids. The posteromedial process is short in adults of Anguis gr. An. fragilis ( Fig. 25K, L View Figure 25 ; slightly longer in juveniles), but distinctly longer in Pseudopus apodus ( Fig. 25M, N View Figure 25 ). The anterolateral one is not distinctly developed, in particular in Pseudopus apodus , whose septomaxilla has a subtriangular aspect in dorsal view ( Fig. 25M, N View Figure 25 ). The posterolateral process bends dorsally and, in Pseudopus apodus , gains a pointed shape in dorsal view. In some features this bone resembles that of scincids: these are the greater posterior development of the ridge on the medial margin and the presence of the arched ridge on the ventral surface (which appears to be more developed in anguids).
PALATINE
The paired palatine ( Fig. 26 View Figure 26 ) is an anteroposteriorly elongated bone composed of three processes: the vomerine, maxillary and pterygoid processes, developed in anterior, lateral and posterior directions, respectively. The pterygoid process is always the longest one. On the dorsal surface of the bone, a palatine ridge runs transversely between the vomerine and maxillary processes, separating them, whereas the ventral surface of the palatine is characterized by the presence of the choanal duct. The maxillary process is pierced by the wide infraorbital foramen. Palatine teeth can be present on the ventral surface of the pterygoid process.
