(n.) Any lizard of the family Geckonidae. The geckoes are small, carnivorous, mostly nocturnal animals with large eyes and vertical, elliptical pupils.

They are numerous in warm countries, and a few species are found in Europe and the United States. See Wall gecko, Fanfoot.

Salamander

(n.) A large poker.
(n.) Solidified material in a furnace hearth.
