Subfamily IV. SCLERURIN^. 



Structure of Sclerurus umhretta. 



This subfamily contains only the single curious genus Sclerurus. 

 which, although it has the spiny tail of the Dendrocolaptiiui', com- 

 bines with that organ the longer tarsi and habits of a terrestrial 

 bird, and is said to keep entirely to the ground. Several authors 

 have reft^rrcd this form to the Formicariidce ; but its proper place 

 seems to be here.
