Genus HYLORCHILUS Nelson. 



HylorchilusC' Nelson, Auk, xiv, no. 1, Jan., 1897, 71. (Type, Catherpes sumi- 

 chrasti Lawrence. ) 



Large TroglodytidEe (exposed culmen more that 25 mm., tarsus more 

 than 30 mm.) with the inner toe (without claw) reaching to but not 

 l)e3'ond penultimate joint of middle toe, tail less than twice as long as 

 tarsus (the latter nearl}- half as long as wing), ninth primar}" much 

 shorter than secondaries, and the tail uniform blackish brown. 



Bill very long, straight; exposed culmen more than two-fifths as long 

 as wing, nearly or quite as long as tarsus, straight to near tip where 

 gently decurved; gonys decidedly shorter than distance from nostril 

 to tip of maxilla, straight, its base very slightly prominent; depth of 

 hill at frontal antia? equal to its width at same point; maxillary tomium 

 without subterminal notch. Nostril obliquelj^ longitudinal (its pos- 

 terior end higher than anterior), narrowly guttate or fusiform, over- 

 hung by a distinct, corneous, excurrent opercidum. Rictal bristles 

 obsolete; feathers of latero-frontal antise advancing nearl}^ to posterior 

 end of nostril. Wing short, excessively rounded, extremely concave 

 beneath; fifth, fourth, third, and second primaries longest, the sixth 

 scarcely longer than first, seventh about equal to first, eighth not longer 

 than secondaries, ninth very much shorter than secondaries, and tenth 

 two-thirds as long as ninth. Tail less than twice as long as tarsus, the 

 rectrices rather loose-webbed, apparently acuminate at tip with the 

 stiffened though slender shaft somewhat projecting.'^ Tarsus very 

 long (nearly half as long as wing, equal to or longer than exposed cul- 

 men), the acrotarsium distinctly scutellate, but planta tarsi on ))oth 

 sides booted; middle toe, with claw, decidedly shorter than tarsus; 

 lateral toes very unequal in length, the inner (without claw) reaching 

 onh' to middle (subterminal) joint of middle toe, the outer reaching to 

 middle of subterminal phalanx of middle toe, its claw reaching to base 

 of middle claw; hallux (without claw) shorter than outer, l)ut some- 

 what longer than inner toe (without claw), its claw mucli shorter than 



oFrom"r/l77, forest- dpjfi/lo?, wren. 



^Of the two specimens examined (the only ones known) only one has any of the 

 rectrices remaining, and this has only five, most of these with the ends l)roken off; 

 consequently I am unable to properly describe this portion of the bird's anatomy.
