This species is rather larger than the last, from which it differs in wanting the white nuchal collar and in being pure white beneath throughout; the white frontal band is very narrow or wanting, the supercilia are also narrower, and the black bands from the eye broader than in M. eutolmus. The white bars on the inner webs of the quills are also narrower.
Bill and feet black ; iris brown (Hartert).
Length about 7.5; tail 3; wing 4.5; tarsus 1.1; bill from gape .55.
Distribution. Upper Assam, the Daphla and other hills to the northward, and the Naga hills to the southward. A specimen was obtained by Godwin-Austen from Lukhipur, Cachar, but none was seen by Hume in Manipur.
