 present, also some median wing-coverts like those of the adult male; 

 all the secondaries and secondary-coverts are blackish brown, finely 

 mottled with chestnut, except the second quill, which is barred with 

 buft' like that of the female. The chest and breast are chestnut, 

 with hero and there an adult feather. The tail is much like that 

 of the female, hut the two outer pairs of feathers are black. 



In an hnmatKre male some of the outer secondaries have their 

 inner webs and extremities finely mottled with rufous, otherwise 

 the plumage is like that of the adult. 



Adult female differs chiefly from the female of G. ffallus in 

 the following poiuts : — The fringes to the feathers of the neck and 

 uj>per mantle are darker, more rufous, and not so wide ; the 

 secondaries are black, irregularly barred with buft"; the feathers of 

 the chest and sides are black, mottled with rufous buft' and with 

 whitish shaft-stripes ; the breast and rest of the underparts are 

 white, irregularly liarred and margined with black ; and the tail- 

 feathers are black, thickly mottled with rufous. Comb very small ; 

 no wattles: facial skin not quite so naked as in G. (jallits. Total 

 length 17 inches, wing 7"5, tail 4-9, tarsus 2-4.

 tips of the wing-featlicrs are mottled with pale rufous.
