. Catalogue of the fossil Reptilia and Amphibia in the British Museum (Natural history) ... By Richard Lydekker ... Reptiles, Fossil; Amphibians, Fossil. VAEANID^l. 281 Genus non det. This form, which appears identical with Plestiodon cadurcensis of Filholl, has the teeth tall, cylindrical, and blunt. Hah. Europe (France). R. 377. The greater part of the left dentary bone; from the Upper {Fig.) Eocene (Lower Oligocene) Phosphorites of Caylux (Tarn- et-Garonne), Prance. This specimen (fig. 63) apparently agrees with the fragmentary dentary figured by Filhol in the ' Ann. Sci. GeoL' vol. viii. pi. xxvi. fig. 425, under the name of Plestiodon cadurcensis. That it cannot, however, belong to that genus is shown by the absence of the ridge on the outer side descending from the coronoid; it agrees very closely with the dentary of Dijploglossus and OjoJii- saurus. Noticed by the writer in the ' Geol. Mag.' dec. 3, vol. v. p. Ill, as Placosaurus. Purchased, 1884. Fig. External and inner views of the left dentary bone of an Anguoid Lizard ; from the Phosphorites of Caylux. \. Family VAEANID^E. Postorbital bar incomplete ; temporal arcade complete; supra- temporal fossa not roofed over by dermal bones; both the pre- maxillee and nasals united together. Dentition pleurodont; teeth large ; palate toothless. Haemal surface of the centra of the dorsal vertebrae broad, flat, and devoid of carina. No dermal scutes.
