UPEROLEIA, Gray.
Head large; palate quite toothless; upper jaw with small close teeth; tympanum hid under the skin; toes of the fore and hind feet elongate, slender, quite free; ankle with a roundish external and a small conical inner tubercle; tongue small, oblong, roundish, and entire behind.
This genus is most nearly allied to Leiuperus of Messieurs Dumeril and Bibron, with which it agrees in having no teeth on the palate, but it differs from it in the tympanum being quite hid.
The internal nostrils are some distance in front of the cross-ridge on which the palatine teeth are generally placed.
