deep gorges, such as that of the Rio Sucio, where all of the highland 

 fauna tends to inhabit lower levels. Its habits are those of Auto- 

 molus, frequenting low tangled jungle, especially masses of vines, where 

 it hops about from limb to limb, but does not do much climbing. It 

 is not an abundant bird in any locality, and must always be sought for 

 in the cool, wet undergrowth along the side of some ravine or beside 

 a little mountain brook. It is much more noisy than Automolus y 

 in that respect resembling Pseudocolaptes.

Mr. Ridgway has characterized a new genus of which this species is 

 the type, giving it as related to Philydor Spix but with a relatively 

 much longer bill (exposed culmen much longer than tarsus), and 

 differing from Automolus in more extensive cohesion of the anterior toes, 

 the basal phalanx of the middle toe being entirely united to both 

 lateral toes. 



The species is confined to the lowlands of the Caribbean and the 

 southwestern Pacific, probably from the Rio Grande de Tarcoles south- 

 ward, although there are no records for the species north of the upper 

 Terraba Valley. It is found from near sea-level up to about 1,500 

 feet, and inhabits the dense undergrowth of the opener parts of the 

 forest. Its habits are the same as those of Automolus. If it has any 

 call I have never heard it, while the bird is inclined to be more sluggish 

 than most of the Dendrocolaptine forms.
