I. Devonshire (Colonel Montagu). Even allowing for the length of time 

 since this specimen was preserved, it must, when freshly killed, have been 

 a very pale-coloured bird, judging from its nearly uniform quills and facial 

 disk, the latter blending with the ruff, which is silvery white, excepting for 

 a slight tip of brown to some of the lower feathers ; under surface pure 

 white ; tail pale orange-buff, with four narrow dissolving bands ; the tail 

 without mottlings at the tip, and the breaking- up of the bands showing that 

 these become gradually dissolved when the species gains its fully adult 

 plumage. Middle toe I'l inch.
