Trachysaurus rugosus (n.s.) T.squamis dorsi rugosis, caudae subspinosis; cauda brevissima.
The body nearly uniform, chestnut brown; the head depressed with the scales convex, and more nearly of an equal size than usual: those round the eyes and mouth large; the three anterior scales on the edge of the lower jaw larger than those which cover the lower surface of the head, body, and tail, which are uniform, distinct, large, and membranaceous: the scales of the back are nearly of equal size with those covering the commencement of the tail; they are furnished with a prominent midrib, and end in a point.

The legs very short, compressed, covered with nearly smooth, rather thin, scales.

The toes very short; claws rather thick, and short.

The tail about half the length of the body.
Head, three inches long.
Body, seven inches.
Tail, four inches.
Only one specimen of this exceedingly interesting animal was brought home by Captain King, but the spirits in which it had been preserved had unfortunately evaporated, so that it was considerably injured; there is, however, a specimen, apparently of the same animal, in the collection of the Linnean Society, which wants the end of its tail.
The above specimen was found at King George the Third's Sound, and is preserved in the Museum.
