Chapman — New Birds Peru, Bolivia, Brazil, Colombia. 259 



Hylocryptus erythrocephalus, new species. 



Specific characters. — In general coloration somewhat suggesting the 

 Automolus rubiginosus- A. nigricauda group, but whole head and neck 

 sharply defined in color from rest of the body; under parts grayish olive, 

 etc. 



Type.— No. 163,086, Am. Mus. Nat. Hist., 9 ad., Alamor, 4300 ft., 

 Peruvian-Ecuador boundary, July 14, 1919; H. Watkins. 



Description of type.— -Head all around, including nape, cheeks, auriculars, 

 and throat between Sanford's brown and orange-rufous (throat more 

 ochraceous-orange) clearly defined, especially on the nape and sides of the 

 neck, from the Dresden-brown back and pale grayish olive under parts; 

 rump tinged with orange-rufous passing into pure orange-rufous on the 

 upper tail-coverts; rectrices slightly deeper in tone than head; wing-quills 

 externally somewhat duller with a faint olivaceous tinge; inner webs and 

 tips of primaries (all but base of outer ones) blackish; inner quills and 

 wing-coverts wholly orange-rufous; bend of the wing and under wing- 

 coverts ochraceous-orange; flanks and ventral region washed with the 

 color of the back; lower tail-coverts ochraceous-orange; feet brownish 

 black; maxilla dark brown, lighter terminally; mandible horn color. Wing 

 92; tail 83; tarsus 28; hind toe 21; outer toe 19.50; middle toe 26.5; inner 

 toe, 17 (all with nail); culmen from base, 30; bill from nostril, 22; depth 

 at gonydeal angle 6.5 mm. 



Description of immature female. — A not fully adult female from Paletilla 

 agrees in size with the type and differs in color only in the presence of nar- 

 row blackish terminal margins on the feathers of the occiput and under 

 parts. 



Specimens examined. — Hylocryptus erythrocephalus. Alamor, 1 $ ad., 

 Paletilla, 1 9 ad., 1 9 im. 



Automolus rubiginosus, A. rufipectus, A. cinnamomeigula, A. nigricauda, 

 and other less nearly related species of the genus. 



Remarks. — The type of coloration shown by this species is unlike that 

 of any furnariine or dendrocolaptine bird known to me. It is conceivable, 

 however, that an intensification of color which would obscure the contrast 

 between the colors of the head and body, might produce some such result 

 as appears in Automolus nigricauda nigricauda of western Ecuador. The 

 latter, however, is a true Automolus of the A. rubiginosus- A. rufipectus 

 group, with the bill no longer than the tarsus and with an ascending in- 

 stead of decurved gonys; the tail-feathers, furthermore, are slightly stiff er. 



Xenops rutilus connectens, new subspecies. 



Subspecific characters. — Intermediate between Xenops rutilus rutilus 

 Licht., and Xenops rutilus helerurus Cab. & Hein., with the tail-pattern 

 of the former and the general coloration of the latter.

 ft., Prov. Cochabamba, Bolivia, July 27, 1915; Miller & Boyle.
