The corneous covering of the nares and its sudden compression 

 and equal breadth beyond these form the distinguishing charac- 

 ter of this genus, in which it differs both from the two following 

 genera, and from that extensive group which comprises Certhia, 

 Nectarinia and Cinmjris. The prominent, rounded and very 

 gradually attenuated , back or culmen is also peculiar to this 

 genus.
