The genus Sphenocichla contains two remarkable and but little-known birds. They are in appearance stout, rather squat and heavy-looking birds with very powerful feet and legs. The bill is perfectly conical and sharp-pointed when viewed laterally and is about the length of the head or a little shorter; there are no rictal bristles; the wing is short and rounded; the tail is of twelve feathers and greatly rounded, the outer feathers being about two-thirds the length of the central. The sexes are alike but the young are still unknown.
