There is one trogon - green and crimson, a brightly coloured ground thrush (Pitta), numerous woodpeckers and barbets; glossy starlings, the black and white African crow and a great variety of brilliantly coloured weaver birds, waxbills, shrikes and sun-birds.
Next he places the parrots (q.v.), and then the vast assemblage of " Passereaux "- which he declares to be all of one type, even genera like Pipra (manakin, q.v.) and Pitta - and concludes with the somewhat heterogeneous conglomeration of forms, beginning with Cypselus (swift, q.v.), that so many systematists have been accustomed to call Picariae, though to them as a group he assigns no name.
As instances of procryptic or celative coloration may be mentioned that of the species of the genus Dolomedes, one of the Lycosidae, which lives amongst reeds and is marked with a pair of longitudinal yellow lines which harmonize with the upright stalks of the vegetation, and Lycosa pitta, which lives on the sand, can scarcely be seen on account of its mottled pattern: Sparassus smargdulus and the species of Pecucetia, which are found amongst grass or low green herbage, are mostly green in colour, and Salticus scenicus is banded with white and black to match the grey tint of the rocks and stone walls on which it hunts its prey.
