Immature birds have the pileum partly brown and fledg- 
lings have the large black barrings on the flanks imperfectly 
developed. The distribution and number of the curious fila- 
mentous white feathers with spatulate tips on the head and 
breast is very variable and irregular but they are not present 
in young birds. 
The flesh of this bird is firm and white, but somewhat dry, 
and inferior for the table to that of Caloperdix oculea, Rollulus 
roulvoul and Tropidoperdix charltont.

“Tris hazel, bill brownish horn, feet yellowish brown.” 
Compared with seven specimens of the typical race from 
the Malay Peninsula, this bird agrees with Ogilvie Grant’s 
diagnosis in being decidedly darker above, having the feathers 
of the crown and the middle of the breast with a subterminal 
bar of black and the primaries and secondaries darker greyish 
olive. 
The bars on the black feathers of the mantle run almost 
straight across the feather and are yellowish, not pure white 
in tone. In the mainland form the bars are semi-lunate, 
following the outline of the feather, giving a squamate 
appearance.
