Ecuador Pileum bister brown; rest of upper parts mummy brown; 

 tail plain fuscous, edged externally with the color of the back; wings 

 fa-cous the lesser and median coverts mummy brown, the latter 

 broadly tipped with dull rufous; the greater series bister, tipped as 

 the median series; outer webs of the secondaries with narrow dul 

 rufous margins, those of the innermost more extensive and somewhat 

 paler- superciliarv stripe brownish white; lores and auriculars like the 

 pileum- cheeks brownish white; chin and upper throat dull white; 

 sides of breast mummy brown, the breast pale brownish; remainder 

 of lower surface pale dusky brownish yellow, the sides rather duller; 

 lining of wing light yellowish. Length of wing, Oi mm.; tail, m 

 mm - exposed culmen, 10 mm. ; tarsus, 20.5 mm. ; middle toe, 10.5 mm. 

 The differences characterizing this new form are not such as may 

 be o-ravjhicallv described, but they are nevertheless quite apparent on 

 coinparison of specimens. The rufescent hue pervading the upper 

 parts is prevalent also on the sides of the breast and adjacent portion 

 of the neck, invading as well to an appreciable extent the brownish suf- 

 fusion of the breast. The two races appear to be alike in size. 



The type of (h-hthnrra riiliunirqinata, which has been examined in 

 the American Museum of Natural History, came from Quito Valley, 

 and represents apparently the Inrd found on the central and western 

 Andes, while this new form, evidently but a subspecies, is its reprc; 

 sentative on the eastern slope of these mountains.

D<'scrlpthn.—Txv^, No. 42422, American Museum of Natural His- 

 tory, collection of Cxeorge N. Lawrence; Ecuador. Pileum dull 

 brownish gray; remaining upper parts a medium shade of olive 

 brown, the upper tail-coverts noticeably paler and more brownish; 

 wings and tail fuscous, margined with the color of the back the 

 greater and median wing-coverts l)roadly tipped with yellowish white 

 producing two wing-bars; a broad superciliary stripe white; lores and 

 a small postocular streak dark brown; cheeks and sides of neck dull 

 brownish white; under surface white, anteriody washed with brownish, 

 the sides, flanks, and crissum tinged with yellowish: lining of wing- 

 yellowish white. Length of wing, 59 mm.; tail, 52 .nm.; exposed 

 culmen, 7 mm.; tarsus, 17.5 mm.; middle toe, 9 mm. 



The single specimen of this bird differs so greatly from examples 

 of Mecocerciilus stlctopteni. that its distinctness seems to be certain 

 It may, however, ultimately prove to be but a subspecies, although 

 evidently a very well-marked one. 



The type is^he only specimen examined, and for permission to 

 describe it the writer is i.idebted to the authorities of the American 

 :SIusenm of Natural History, through Hr. J. A. Allen.
