Nos. 3740, — . c? d ad. Pueblo Rico (5200 ft.), 7.ix. ; Siato

" Iris brown, feet greyish green, maxilla black, mandible light 

 brown." 



The adult birds fully bear out the characters given by Mr. 

 Ridgway for his subspecies which, moreover, was based upon 

 one of Palmer's skins. S. e. griseigidaris may easily be recog- 

 nized from its allies : iS. e. erythrops ScL, of Western Ecuador, 

 and S. e. rufigenis Lawr.*, of Chiriqui and Costa Rica, by its 

 mouse-grey (instead of biiffy brown) foreneck and breast, and 

 brighter cinnamon-rufous median rectrices. 



S. e. gj'iseigidaris is peculiar to the elevated districts of the 

 Western Cordillera of Colombia. 



[105. Thripadectes solateri Berl. 



Thripadectes sc?rt^eri Berlepsch, Ornis, xiv. p. 365 (Feb. 1907. — 

 S. Pablo, W. Colombia, 4500 ft. ; G. Hopke coll.).

 (1910.— Pavas, W. Colombia, 4400 ft. ; M. G. Palmer coll.). 



Count Berlepsch having kindly submitted to my inspection the 

 type specimen, I can positively state that 7^. alogus is merely a 

 sj'nonym of T. sclateri, the description of which appears to haA^e 

 been oveilooked bj^ Mr. Bangs. The two tA'pes wei'e obtained in 

 the same disti^ict, viz., in the Western Cordillera above Buena- 

 ventura, Choco Bay. Although someivhat resembling Automolus 

 [Rhopoctites) rvfohrunneus in general coloration, T. sclateri is a very 

 distinct species, and I agree with its describer that it finds its 

 natural place in the genus Thripadectes. The structural characters, 

 especially the shape and size of the bill, are exactly the same as 

 in T. flamm.idatv.s, while A. rufobntnneus has a much shoi"ter, 

 slenderer, more depressed bill, and much shorter, weaker tarsi. 

 The pileum has distinct, though narrow, pale shaft-lines, whereas 

 it is uniform dusky olive in A. riifobrunneus; the back is darker, 

 less reddish ; the throat much paler, light ochraceons instead of 

 deep orange ; the sides of the neck are olive-brown instead of 

 orange-ochraceous ; the breast and abdomen aie darker ochreous
