Lead-coloured (in spirits) with white spots; beneath dirty white, with some small white warts at the angle of the mouth; legs smooth. Inhabits Western Australia. 103. Hyla Adelaidensis, Gray, t. 8 f. 2. Slender; fore-toes quite free, hinder toes webbed to the last joint; (in spirits) gray-blue, with a series of small oblong tubercles; the sides purple-brown with a white streak from the underside of the eyes to the shoulders; sides of the belly and region of the vent purplish, with small white spots; the hinder side of the thighs purple-brown, with three large oblong white spots; belly and under side of thighs granular; chin white, brownish dotted; palatine teeth in two roundish groups between the internal nostrils. Inhabits Western Australia. 104. Hyla binoculata, Gray, t. 8, f. 1. Slender; fore-toes quite free; hinder toes webbed to the last joint. Grayish white (in spirits) with a series of very small, indistinct, oblong tubercles, with a dark streak from the nostrils to the shoulder, enclosing the eyes, and a white streak below it from the underside of the eye; sides purplish, with small white spots; back of the thighs purple, with two yellow spots; belly and underside of thighs whitish, granular. Var. 1. Back of thighs with one or two additional yellow spots. Var. 2. Back bluish gray; back of the thighs with six or seven small subequal yellow spots. Inhabits Western Australia. 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. 105. Uperoleia marmorata. Black and green marbled, leaving a triangular greenish spot on the forehead, beneath lead colour. Inhabits Western Australia. Dr. Tschudi has formed a genus under the name of Crinia, which appears by his characters to be nearly related to the above; but Messieurs Dumeril and Bibron (Erp. Gen. 8 416) observe that the specimens he described have two very small groups of teeth on the vomer. 107. Breviceps gouldii, t. 1 f. 1. Smooth, with a few scattered low tubercles; gray-brown (in spirits), yellowish beneath. Inhabits Western Australia. This animal has all the external appearance and character, as far as they are given in Messieurs Dumeril and Bibron's work, of the Breviceps gibbosus of the Cape of Good Hope, except that it has not the yellow dorsal band, and the back is scarcely to be designated as granular. It is the second species of the genus, and only the second Toad found in Australia. ... APPENDIX F.
