Genus LIOTHEIX Swains., 1831. 



The genus Liotlirix contains one remarkable species of hill-bird, 

 which is characterized by a slightly forked tail, the feathers of 

 which are gently curved outwards ; the bill is about half the 

 length of the head, stout and with the culmen curved. It resembles 

 very closely the bill of Mesia, figured below (p. 354). The tail is 

 quite square at the tip and the upper tail-coverts are long. The 

 species extends from Simla in the Western Himalayas, East into 

 China and South into S. Burma and Siam. It is divisible into 

 several geographical races.
