Adult Male. 



Bill nearly as long as the head, subulato-conical, acute, slightly arched, 

 compressed. Mandibles of equal breadth, with acute margins, the gap line 

 a little arched, and slightly deflected at the base. Nostrils basal, oval, half 

 closed by a membrane. Feet longish, proportionally rather robust; tarsus 

 anteriorly scutellate, compressed, acute behind, longer than the middle toe; 

 toes free, scutellate above, the lateral ones nearly equal, the posterior long; 

 claws slender, compressed, acute, arched, that of the hind toe much larger. 



Plumage rather compact above, blended beneath. Wings short, very 

 convex, rounded; first quill short, third and fourth longest. Tail erect, long, 

 of ten feathers, much rounded, the outer feather not more than half the 

 length of the middle one, all rounded at the end. 



Bill blackish-brown above, pale blue beneath. Iris brown. Feet and 

 claws pale brown. The general colour of the upper parts is rusty brown, 

 that of the lower greyish-blue. Quills and wing-coverts barred with rusty 

 brown and black, as are the two middle tail-feathers. Outer web of the 

 lateral tail-feather, and the terminal portion of that of the others, whitish, 

 barred with black, their middle parts black, toward the base barred with 

 rusty brown. A line of pale brownish-yellow extending from the upper 

 mandible, over the eye, to half way down the neck. The rump feathers 

 white towards their base, with central spots. 



A specimen in my possession measures 5 T 5 2 inches in length; the bill ■£ § ; 

 tarsus T 9 2; hind toe ff, its claw ff; middle toe -||, its claw ff; wing from 

 flexure 2^1 tail 2^. The first quill is T 9 2 shorter than the fifth, which is 

 longest, but scarcely exceeds the fourth and sixth. The lateral tail-feathers 

 are ?$ shorter than the middle.
