Culmen rounded. The tip of the upper mandible entire, broader than high, and slightly bent over the lower. Wings long, pointed; the first quill nearly equal to the second and third, which are longest; tertials lengthened. Tail slightly forked. Feet slender. Anterior toes rather short; the lateral ones unequal, the claws small; hind toe as long as the middle toe, but shorter than the tarsus; the claw much lengthened, and slightly curved.  Chili.   G. anthoïdes.  Part 5. No. 129." (Swainson 1837 (Classif. Birds)); "129. GEOSITTA anthoïdes.  ...  Inhabits Chili." (Swainson 1837 (Anim. Menag.)); "Geositta SWAINSON, Classif.
