Coloration. Resembles M. rubricapillus. Differs in having the cheeks, chin, throat, and upper breast with broad black shaft-streaks (not black shafts merely); the crown of a chestnut-brown (not pale ferruginous) ; the upper plumage more rufous, and the exposed parts of the wings castaneous.
Iris pale red-brown ; lower mandible and orbital skin pale blue; rest of bill bluish brown ; legs and feet greenish brown (Davison).
Of very slightly larger size than M. rubricapillus.
In addition to the points of difference noted above as existing between this species and M. rubricapillus, it should be observed that the iris is red-brown as recorded by Davison.
Distribution. Southern Tenasserim from Mergui, extending down the Malay peninsula to Sumatra.
