The Rusty-throated Blue Wood-Chat, Jerd. 



Coloration. Male. Forehead continued back as a supercilium, 

 the upper tail-coverts, and a patch on the lesser wing-coverts near 

 the edge of the wing bright ultramarine-blue; ear-coverts, lores, 

 and in front of the eye black ; upper plumage and the sides of the 

 head and neck deep purplish blue ; wing-coverts and quills black, 

 edged with purplish blue ; tail black, suffused with purplish blue 

 on the outer webs ; chin, throat, breast, and abdomen chestnut ; 

 vent and under tail-coverts white ; under wing-coverts and axil- 

 laries pale chestnut. 



Female. Upper plumage and the visible portion of the closed 

 wing olive-brown tinged with rufous ; rump slaty blue ; upper 

 tail-coverts deep blue ; tail black, the outer webs suffused with 

 deep blue ; sides of the head fulvous olive-brown ; lower plumage, 

 under wing-coverts, and axillaries rich ochraceous, becoming white 

 on the vent and under tail-coverts. 



I have not been able to examine a young bird, but it will prove, 

 without doubt, to be spotted. 



Bill black in the dry skin ; legs and feet brown. 



Length about 5-5 ; tail 2-3 ; wing 3'2 ; tarsus 1 ; bill from 

 gape -6. 



Distribution. Sikhim and the Khasi hills. In the former tract 

 this species is a resident, probably moving vertically according to 

 season. This bird is figured by Hodgson, and there are likewise 

 some specimens collected by him in the British Museum, probably 

 from Nepal, but there is no certainty on this point. 



Genus ADELURA, Bonap., 1854. 



The sole member of this genus is frequently associated with the 

 true Redstarts, but the total absence of the chestnut in the tail, 

 which forms so conspicuous a feature in all the Redstarts, induces 

 me to place the present type apart from them. In habits this 

 species appears to be a Redstart, and structurally it does not 

 differ from Ruticilla. From lanthia, which it somewhat resembles 

 in coloration, this genus differs in having the tips of the tail- 

 feathers rounded.
