Alfred Russel Wallace,
A narrative of travels on the Amazon and Rio Negro…
(1853)
“ In every garden, road, and dry sandy situation they are scampering out of the way as we walk along. Now they crawl round the trunk of a tree, watching us as we pass, and keeping carefully out of sight, just as a squirrel will do under similar circumstances; now they walk up a smooth wall or paling as composedly and securely as if they had the plain earth beneath them. Some are of a dark coppery colour, some with backs of the most brilliant silky green and blue, and others marked with delicate shades and lines of yellow and brown. ”
