Coloration. Very similar to that of D. insignis, from which the present species differs in having the crown and sides of the head pure french-grey, darker than the lower parts and contrasting strongly with the pinkish grey or reddish lilac of the hind neck. The upper back and smaller wing-coverts are more coppery and the rump darker and less grey than in D. insignis.
Bill reddish plum-colour, pale at the tip ; irides greyish white, orbits grey-brown (Wardlaiv-Ramsay); legs and feet purplish lake; soles whity-brown (Hume). Measurements as in D. insignis.
Distribution. Hill-ranges of Assam, Manipur, Arrakan, and Tenasseriin. In the Assam ranges some birds appear to be intermediate between this and D. insignis. Specimens (referred to insignis) from Arrakan were presented by Sir A. Phayre to the Asiatic Society in 1844.
Habits, &c. Those of the genus. An egg obtained by Davison on Mooleyit, west of Moulmein, on January 27th measured 1.61 by 1.15.
This bird may, like the next species, visit the sea-coast at particular seasons, and if so is probably the pigeon seen by Davison at Mergui in August (S. P. vi, p. 417). Hume suggests that the species was the Malaccan D. badia, which may be known by its smaller size and coppery-red mantle.
