Coloration. Resembles M. olscura, but differs in the following respects : the breast and sides of the body in both sexes are slaty grey, not chestnut-brown ; the upper plumage in both sexes is russet-brown, not olive-brown ; the crown in the adult male is never darker than the other upper parts ; the sides of the head and the
sides of the chin and throat are russet-brown, not slaty brown ; and in the adult male the throat itself is slaty grey, not slaty brown.
Iris deep chocolate ; bill black ; legs pale cloudy brown ( Wardlaw Ramsay) ; legs and feet brownish yellow ; bill blackish brown, yellow at gape and on base of lower mandible ; iris brown (Hume).
Of the same dimensions as M. obscura.
This Ouzel resembles M. pallida, Ginelin, but may be instantly distinguished from that species by the presence of a supercilium, which is altogether absent in M. pallida. The latter inhabits Eastern Asia and may occasionally visit Burma.
Distribution. Shillong and Cherra Poonjee ; Japvo peak in the Naga hills at 10,000 feet; Manipur; Karennee at 5000 feet; Muleyit mountain in Tenasserim.
All the specimens of this species that I have examined from the above localities were procured in the winter months, but this Ouzel is not unlikely to prove a resident species in those parts.
G-enus CKEOCICHLA, Kuhl (teste Gould), 1836.
In the Thrushes of this genus the sexes are different and the under wing-coverts and axillaries are each of two colours, the position of the two colours on the under wing-coverts being transposed on the axillaries.
From Merula this genus differs in having a somewhat blunter wing and shorter tail. The underside of the wing presents a pattern formed by the white bases of many of the quills.
