and the holes of the ears being furnished on
their front part with a fringe. It differs from the succeeding Genus,
Trachysaurus, in the head being covered with distinct flat plates, and
the whole of the body with cut hexangular scales; the scales are harder
than those of the true Skink, but not so distinctly bony as those of the
Trachysaurus.

This Lizard, which was first described in the excellent journal of Mr.
White, does not appear to be uncommon on the coast of Australia, as there
are several specimens both in the British Museum and in the collection of
the Linnean Society, that were probably taken in the neighbourhood of the
colony; the specimen before me was caught at Seal Island, in King George
the Third's Sound.

The scales of the whole of the body are broad, hexangular, with five or
six longitudinal, slightly-raised ridges, which gradually taper, and are
lost just before they reach the margin. The legs are short, thick; the
toes of the fore-feet are rather short, the outer reaching to the middle
of the second, the second and third equal; the fourth reaching to the
last joint of the third, and the little one to the second joint of the
fourth finger. In the hind foot the first and third toe are nearly equal,
and only half as long as the second; the fourth only half as long as the
third; and the fifth about half the length of the fourth toe.

Genus TRACHYSAURUS. Gray.

Pedes quatuor pentadactyli.
Caput sub-scutatum, dentes in palato nulli.
Truncus supra sqoamis crassis elongatis subspinosis, infra hexagonis
membranaceis imbricatis, tectus.
Cauda brevis, depressa.

This genus is at once distinguished from the former, and indeed from the
whole of the Scincidae, by the large hard scales that cover the back of
the body and head; which are formed of distinct triangular long plates,
rough on the outside, and covered with a membranaceous skin. The body
shields of the head pass gradually into the dorsal plates. The teeth
short, thick, and conical; the palate toothless. The belly and lower
surface of the tail are covered with large six-sided scales, like the
other genera of the family. The head is rather large, triangular. The
legs short, w
