Males differ from F. I. lathami (Hartl. 1854) in having the 

 cheeks and upper side of the neck light pearl-grey or pure 

 white ; the flank-feathers black with white spots, cordate 

 or circular in shape. In F. I. lathami the cheeks are a dull 

 grey. In F. I. schubotzi the abdomen is dirty-white with 

 black cross-bars, in F. I. lathami white washed with brownish 

 and only faintly barred. The spotting on the under surface 

 is smaller and very much finer towards the neck ; the spots 

 are large in F. I. lathami. The flanks are brown with 

 white shaft-streaks, in F. I. lathami brown with white 

 spots. In this subspecies the under tail-coverts are black 

 with white shaft-stripes and slight barring, black with white 

 cross-bars in F. I. lathami. 



The females differ in much the same way as do the males, 

 but in this subspecies the cheeks and side of the neck are 

 invariably reddish brown, not greyish. The white spotting 

 on the neck and upper breast is confined to narrow shaft- 

 streaks. 



Young males differ from adults in having the head 

 mottled, the feathers being tipped with black ; the chin 

 and throat white ; the sides of the head and ear-coverts 

 brownish, as in females ; the feathers of the breast and 

 abdomen brown with white cross-shaped markings outlined 

 in black ; the flanks lighter brown with whitish shaft-streaks 

 and faint vermiculations. The upper surface is strong reddish 

 brown heavily marbled in black, the scapular feathers having 

 an ochraceous shaft-stripe. 



These biids go in pairs or small coveys, and are very shy 

 and difficult to procure. Breeding-birds were shot in June, 

 and young, of about a month old, obtained in September.
