Legs and feet dark chocolate-brown; upper mandible black; lower mandible pale reddish brown ; iris dark brown ; mouth pale salmon-colour.

Distribution. Pegu east of the Irrawaddy river, from the sea up to a few miles north of the town of Pegu; Tenasserim from Toungngoo down to Tenasserim town and the Thoungyeen valley. The limits of this species to the north and west are unknown, and it must remain doubtful for the present whether this Sun-bird extends to Arrakan or not.
