100 TUBDIDJE. 



It is seldom that the male is in the full plumage described above. 

 The amount of blue and chestnut on the throat varies much ; and 

 sometimes only the presence of a few blue feathers serves to indicate 

 that the bird is a male. 



The nestling is blackish above streaked with fulvous, and fulvous 

 below, each feather edged with black. 



Bill black, the base flesh-colour ; iris brown ; eyelids plumbeous ; 

 inside of mouth yellowish ; legs dusky fleshy ; claws brown. 



Length 5-9 ; tail 2'3 ; wing 2-9 ; tarsus Ivl ; bill from gape '75. 



Distribution. A winter visitor to almost every portion of the 

 Empire and Ceylon. The only parts from which this species has 

 not yet been recorded are the Nicobar Islands and the portion of 

 Tenasserim south of Tavoy, but even in these it probably occurs. 



In summer this species is found immediately north of the 

 Himalayas and thence through Asia to the Arctic Circle, extending 

 west throughout Europe and east to the Pacific. In winter it is 

 found not only in India but in North Africa on the one hand and 

 in Southern China on the other.

Coloration, liesembles C. suecica, the male differing from the 

 male of that species in having the patch on the throat white instead 

 of chestnut, or in wanting a spot altogether. The females and 

 young of the two species appear to be inseparable. 



Distribution. A rare visitor to the extreme north of Kashmir, 

 occasionally straggling even to the plains. Biddulph secured a 

 specimen in Grilgit in April, and he records this species as very 

 common on both sides of the Digar pass, between the Nubra and 

 Indus valleys. In the Hume Collection there is a specimen which 

 was obtained in Tirhoot in April, and Hume states that he has seen 

 some half-dozen specimens from various parts of India. 



The headquarters of this Blue-throat are Europe in the summer, 

 and North Africa and Palestine in the winter. 



Genus DAULIAS, Boie, 1831. 



The genus Daulias contains the Nightingales, birds of plain 

 plumage but of great powers of song. The one species that has 

 been known to occur in India is of extreme rarity in that country, 

 only two instances of its occurrence being known. 



In Daulias the whole plumage is brown, somewhat ruddy on the
