This peculiar Brazilia]i monotype is at once recognizable from 

 Scytalopus by the compressed and elevated mesorhinium, the long 

 outstanding loral plumes, and the long rounded tail, which is com- 

 posed of six much graduated pairs of rectrices. The wings are 

 short and rounded ; the tarsi are long, and have the divisions of 

 the scutes clearly indicated.
