Genus LIOTHRIX Swains., 1831. 
The genus Ziothria 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, tigured 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 8. Burma and Siam. It is divisible into 
several geographical races.
