Sharpe separated this genus from Gould’s Poecilodryas on account of its larger 
size, longer bill, stronger legs and feet, and since then it has been generally 
allowed. 
The species are large Poecilodryatine birds with long bills, large rounded 
wings, long square tails and strong legs and feet. 
The bill is long and stout, somewhat flattened, rather narrow with the 
tip slightly decurved, the linear nostrils placed at the base, the rictal bristles 
strong. 
The wing is rounded with the first primary more than half the length of 
the second which is less than the eighth, the third is about equal to the seventh 
while the fourth, fifth and sixth are subequal, the fifth sometimes the longest. 
The tail is long and square. 
The legs are long and stout, the feet strong. 
Probably the above taken from structural characters would prove useless 
unless the coloration was known, which point I deal with in connection yfith the 
succeeding genus, which should in an evolutionary scale probably precede this, 
but the fact that the only known congener of this bird is a New Guinea species 
counsels caution.
