A very extraordinary and not inelegant little creature, having a bill totally different from any other bird. Its general habit evinces a close connexion with the Sittæ, particularly those of New Holland; some of which have their bills (which are slender) slightly inclining upwards, thus forming a connexion between Xenops and the straight billed Sittæ of the old world.

The figure is of the male, and its natural size; the head dark brown with pale spots; the back of a reddish tinge, and the rump and tail rufous; tail much rounded, and of twelve feathers; the three outer and the two pair in the middle entirely rufous, the other pair having the inner shafts black; the greater quills black; the last having an internal bar of pale fulvous. Beneath the eye a spot of white downy feathers, with a dusky border above and below; there is a little difference between this and Illiger's bird, but it may be only sexual.

Inhabits Brazil, but is rare.
