A dark band commences from the hinder part of the lower lip, merging in the throat, and expanding out so as to be united together at the back part of the chin. There is a large rather oblong spot in the centre of the chest and the hinder part of the abdomen, separated from each other by a large somewhat triangular spot on each side of the middle of the abdomen.

Body 4 1/2 inches.

This is the Spinous Lizard exhibited by Mr. Gould at the meeting of the Zoological Society in October 1840.

White, in the Appendix to his Journal, mentions and figures two snakes (n. 1 and 2 page 258) but his descriptions are so short, and his figures so indistinct, compared with what are now required to determine the species of snakes, that I am unable to apply them with certainty to any of the species here recorded.

Varied with a few whitish cross bands; last series of scales and beneath whitish ventral shield black in front; subcaudal plates, one-rowed; throat scaly; chin shields two pairs; eyes lateral, pupil round; front pair of frontal plates short; nostrils lateral, in two small shields, loreal shields none; one large anterior, and two moderate posterior ocular shields; lower temporal shield in the labial ones.
