Genus SUTHORA, Hodgs., 1838. 



The genus Suthora contains seven Indian birds which with one 

 exception are of very small size. Jerdon and others have assigned 

 these seven birds to three genera, Hcteromorpha, Chlsuasicus and 

 Suthora. I consider them absolutely congeneric and have failed 

 to tind a single structural character by which to separate them. 



This genus differs from the last in its relatively smaller bill 

 (which is also of less depth as compared with its length) and in 

 the commissure being much less curved. From the next genus it 

 may be separated by its much longer tail. 



Many of these birds are very prettily coloured, and they appear 

 to resemble the Tits in their habits, feeding on insects, for winch 

 they search the branches and leaves of trees. Nothing whatever is 

 known about their nidificatiou.
