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.
