Gray.
Capite depresso; membrana tympani aperta.
Gula pennulis plicatis ornata.
Pedibus quatuor.
Digitis quinque, elongatis, simplicibus.
Cauda elongata, subcylindrica.
Animal scaly; the head depressed; the nostrils placed on the side, midway between the eyes and the end of the head; the drum of the ear naked; the front teeth conical, awl-shaped (eight in the upper, and four in the lower jaw); the hinder ones largest; the side or cheek teeth compressed, short, forming a single ridge, gradually longer behind; tongue short, fleshy, with an oval smooth disk at each side of the lower part of its front part; neck rather long, furnished on each side with a large plaited frill, supported above by a crescent-shaped cartilage arising from the upper hinder part of the ear, and, in the middle, by an elongation of the side fork of the bone of the tongue; body compressed; legs rather long, especially the hinder ones; destitute of femoral pores; feet four, with five toes, the first having two, the second three, the third four, the fourth five, and the little finger and toe three joints; claws compressed, hooked; tail long, nearly round, scaly.
This genus appears to be nearly allied to the Agamae, but differs from them in the peculiar frill that is appended to the neck.

Table A.Natural size.
Inhabits Port Nelson, north-west coast of Australia.
The colour yellowish-brown variegated with black: the head depressed, with the sides erect, leaving a blunt ridge on the upper part, in which the eyes are placed: the ridge over the eyes covered with larger scales than those over the head; eyes rather small, with a fleshy ridge above them; eye-lids covered with minute, and surrounded by a delicate serrated ridge of small upright scales: the lips surrounded by a row of oblong, four-sided scales, arranged lengthways, the front scale of the upper lip being the largest: the chin covered with narrow mid-ribbed scales, with a five-sided one in the centre, and several of larger size just over the front of the fork of the lower jaw: nostrils, surrounded by rather a large orbicular scale, situated nearly mid-way between the eye and the end of the upper jaw, the tubes pointing forwards: the side of the face has a very obscure ridge extending from the angle of the mouth to the under part of the ear: neck covered with small scales: frill arising from the hinder part of the head, just over the front of the ears, and attached to the sides of the neck and extending down to the front part of the chest, supported above by a lunate cartilage arising from the hinder dorsal part of the ear, and in the centre by a bone, which extends about half its length: this bone appears to be an elongation of the side fork of the bone of the tongue, but it could not be determined with certainty without injuring the specimen; each frill has four plaits, which converge on the under part of the chin, and fold it up on the side, and a fifth where the two are united in the centre of the lower part of the neck; the front part of its upper edge is elegantly serrated, but the hinder or lower part is quite whole; the outer surface is covered with keeled scales, which are largest towards its centre; the inner surface is quite smooth.

The scales of the back are oval, smoothish; those of the lower part of the body and upper part of the legs acutely mid-ribbed, and of the sides and joints of the limbs minute.
