Large Campophagine birds with strong stout bills, long wings, long, straight 
tail and small but stout legs and feet. 
The bill is triangular and stout, the culmen keeled, greatly arched, the 
tip attenuate and sharply decurved and notched ; the sides expand so that at 
the base the width about equals the depth, and is equal to half the length of 
the culmen ; the under mandible is stout, the interramal space very small 
and fully feathered ; the nostrils are placed basally in small nasal grooves 
and are entirely hidden by frontal feathers ; rictal bristles few, strong, but 
not pronounced. The wing is long and pointed, the first primary short and 
narrow and less than the secondaries, and only about half the length of the 
third which slightly exceeds the second ; the third, fourth and fifth are sub- 
equal and longest ; the sixth is longer than the second, but the seventh is 
shorter than the third. 
The tail is long and square, about three-fourths the length of the wing. 
The feet are short and stout ; the tarsus a little longer than the culmen 
shows about four broad scutes anteriorly, and is bilaminate posteriorly ; the 
toes short and as in preceding genus, scutellate. 
Coloration grey above, wings and tail black, as is the face ; throat grey 
under-surface otherwise white. Male and female alike, but young differ a little.
