Coloration. The whole upper plumage olive-brown tinged with 

 rufous, especially on the outer webs of the quills, ail the feathers 

 margined darker, causing a scaly appearance ; tips of the median 

 and greater coverts ochraceous ; tail brown, indistinctly cross-rayed, 

 and the outer feathers paler ; sides of the head mixed fulvous and 

 dark brown; chin, throat, middle of breast, and abdomen white, 

 with brown tips and margins ; sides of the throat, breast, and 

 body dark olive-brown, the feathers of the sides of the throat and 

 upper breast with darker centres ; under tail-coverts pale buff, the 

 feathers broadly margined with olivaceous at the sides; axillaries 

 basally white, then black ; uuder wing-coverts basally black, and

 {Hume Coll.). 



Length about 10 ; tail 3 ; wing 4*9 ; tarsus 1-1 ; bill from 

 gape 1*5. 



Distribution. Sikhim ; Bhutan ; the whole of the Eastern portion 

 of the Empire from the Brahmaputra river to the extreme south 

 of Tenasserim. This species is probably a permanent resident 

 throughout its range. 



Habits, Sfc. Mr. Grammie found the nest of this Thrush in Sikhim 

 at the end of May — a cup composed of moss and fibres and placed 

 on a low branch of a tree. The eggs were three'in number, and 

 one of these is described by Hume as being very pale greenish 

 white much marked with ferruginous-brown and pinky purple. It 

 measured 1*05 by -79. 



Genus C0CH0A, Hodgson, 1836. 



The genus Cochoa contains two species, the position of which 

 remained doubtful for many years. An examination of the young 

 of these birds, however, clearly proves, as shown by Hume, that 

 they belong to the Turdince. 



In Cochoa the sexes differ and the plumage of both sexes is very 

 brilliant. The bill is short and very broad at the base ; the nostrils 

 are large exposed ovals ; the rictal bristles are obsolete; the wing is 

 long and pointed, and the first primary minute ; the tail of moderate 

 length, aud the tarsus short. 



The Thrushes of this genus inhabit forests, go in pairs or small 

 Hocks, feed both on the ground and on trees, and have a harsh 

 note. They make cup-shaped nests in trees, and lay spotted eggs. 

 They are non-migratory.
