and two other bands, much narrower, are formed hj 

 the white tips of the greater and lesser wing-coverts : 

 the feathers in the middle of the back are also pure 

 white, bordered with black across their extremities ; 

 so that when undisturbed, the white portion is almost 

 hid : the wings, although rounded, are larger and 

 more robust than those of the two preceding species : 

 as is also the tail, the feathers of which are broad 

 and obtuse : tarsi rather strong and black.

 Black Ant-Thrush with the base and margins of the interscapu»» 

 lary feathers snowy. 



Length seven inches : greatly allied to the last, 

 but differs in wanting the white bands on the wings r 

 the beak is somewhat larger : the entire plumage is 

 deep and uniform black : it has a concealed spot of 

 white on the back, but instead of the feathers being 

 bordered with black at their tips, they have a tear- 

 shaped spot of that colour, so that the white margin 

 appears externally when the feathers are smooth : 

 the wings are shorter than in Dr. trifasciata, and the 

 tail, although similar in form, is more graduated 5 

 the irides are large and bright crimson.
