 no white on the eyebrow or sides of neck: "bill and legs 

 slaty blue; iris black " (C. M. TV.). Total length 6 inches,

This new species bears at first sight some resemblance to 

 Monarcha inomata in the colour of the abdomen and the 

 grey upper surface, but the close-set plumage of the forehead

 former character placing it in the genus Piezorhynchus. 

 Here its nearest ally is P. richardsi, but it is grey instead of 

 black, and has only a white eyebrow instead of a white hinder 

 crown.
