Forehead, the upper part of the cheeks and round the eye black; ear-coverts black above, whitish tipped with rufous below; upper plumage and sides of neck rufous-brown, brighter on the greater coverts, the outer webs of the quills and on the head, the feathers of which have narrow edges of black; rump tinged with ashy ; tail chestnut-brown ; lower parts of cheeks rufous-brown; extreme point of chin black; remainder of chin, throat, the middle of the breast and abdomen and under tail-coverts white; sides of breast and abdomen ashy.

Measurements. Length about 280 mm.; wing 103 to 108 mm.; tail about 120 mm.; tarsus about 35 mm.; culmen about 20 mm.

Distribution. Nepd, Sikkim, hills North of the Brahmaputra and hill-ranges of North Manipur, Naga Hills to Dibrugarh.

Nidification. Breeds in Sikkim in May and June and occasionally as early as April at between 6,000 and 8,000 feet, making a bulky, cup-shaped nest of twigs, bamboo leaves, grass, roots and stems of plants, lined with finer roots and fern-rachides and placed in small trees or high bushes at any height between 5 and 15 feet. The eggs, two or three in number, are pale blue-green, very like those of Garrulax moniliger, but the texture is smoother and closer though not nearly so hard or glossy as those of the ruficollis group. Fifteen eggs average 30.5 x 22.1 mm.

Habits. Similar to those of the rest of the genus. This bird, however, is one of high altitudes, being found principally between 3,000 and 5,000 feet, and ascending up to 6,000 feet in summer and descending to about 2,000 in winter.
