Adult. Similar to D. flavicollis, but differing in the somewhat 

 browner colour, especially on the wings, being paler and browner on 

 the under surface, and especially distinguished by having the central 

 row of spots down the throat black instead of chestnut, and having 

 an admixture of dull reddish brown instead of chestnut on the fore- 

 neck : " bill dark horn-colour ; feet olive-brown ; iris yellow " 

 (J. Gould). Total length about 24 inches, culmen 3-35, wing 8-9, 

 tail 3*4, tarsus 2-65, middle toe and claw 2'7. 



Adult female. Decidedly duller and browner on the back than the 

 male, the black throat-spots not so distinct, and with a very evident 

 admixture of rufous-brown down the throat and fore-neck. Total 

 length about 21 inches, wing 8-3, tail 2*85, tarsus 2-65, middle toe 

 and claw 2*5. 



Young. Distinguished from the adults by the ochreous margins tO' 

 the feathers of the upper surface, and recognizable from the youngs 

 of D. flavicollis by the black instead of rufous cheeks and sides of 

 face, and by the dingy brown or blackish, instead of rufous, mottling: 

 on the throat and fore-neck.
