e 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. The tail is twice as long as
the body, roundish, covered with acutely mid-ribbed scales, which towards
the end form six rows, so as to render it obscurely six-sided; the end is
blunt: the toes long, very unequal, varying in joints, as stated in the
generic character (which includes also the claw joint) compressed, scaly;
the claws hooked, horn-coloured.

Length of the tail: 12 inches.
Length of the body: 5 inches.
Length of the head: 5 1/2 inches.
Breadth of the head over the eyes: 1 inch.
Length of the thigh: 1 9/10 inches.
Length of the foot and sole: 2 2/10 inches.
Length of the outer edge of the frill: 10 inches.

This interesting lizard was found by Mr. Allan Cunningham, who
accompanied the expedition as His Majesty's Botanical Collector for Kew
Gardens, on the branch of a tree in Careening Bay, at the bottom of Port
Nelson. (See volume 1.) It was sent by him to Sir Everard Home, by whom
it was deposited in the Museum of the College of Surgeons,* which
precluded my examination of its internal structure.

(*Footnote. Upon application to the Board of Curators of the College, I
was permitted to have a drawing made of this curious and unique specimen
for the Appendix of my work. The plate was engraved by Mr. Curtis, from
an exceedingly correct drawing made by my friend, Henry C. Field,
Esquire. P.P.K.)

Respecting this remarkable Lizard, Mr. Cunningham's journal contains the
following remarks. "I secured a lizard of extraordinary appearance, which
had perched itself upon the stem of a small decayed tree. It had a
curious crenated membrane like a ruff or tippet round its neck, covering
its shoulders, and when expanded, which it was enabled to do by means of
transverse slender cartilages, spreads five inches in the form of an open
umbrella. I regret that my eagerness to secure so interesting an animal
did not admit of sufficient time to allow the lizard to show by its alarm
or irritability how far it depended upon, or what use it made of, this
extraordinary membrane when its life was threatened. Its head was rather
large, and eyes, whilst living, rather prominent; its tongue, although
bifid, was short and thick, and appeared
