 fusco-undulatus, uropyyio rufescente; subtus aVoidus post ice rufes-

$ 9> adult: Upper parts pale brownish-gray, minutely* dotted everywhere 

 with blackish and whitish points together, and usually showing obsolete 

 wavy bars of dusky. Rump cinnamon-brown ; a whitish superciliary line ; 

 beneath, soiled white, shading behind into pale cinnamon, the throat and 

 breast obsoletely streaked, and the under tail-coverts barred, with dusky. 

 Quills of the wings rather darker than the back, with similar markings on 

 the outer webs. Middle tail-feathers like the back, with many dark bars of 

 equal width with the lighter ones; lateral tail-feathers similarly marked on 

 the outer webs, plain on the inner webs, with a broad subterminal black 

 baron both webs and cinnamon-brown tips, the latter usually marbled with 

 dusky ; outer feather with several blackish and cinnamon bars on both 

 webs. Bill and feet dark horn color, the former paler at base below. 

 Length, 5J-6 : wing, 2|-2f ; tail, 2J-2f; bill, -f ; tarsus, f-*. 



Most of the markings of this species are blended and diffuse. The shade 

 of the upper parts is quite variable, from dull grayish to a more plumbeous 

 shade, often with a faint pinkish tinge. Specimens in worn and faded plum- 

 age may altogether fail to show the peculiar dotting with black and whitish 

 usually seen ; but, in these, the crosswise dusky undulation, as well as the 

 streaks on the breast, are commonly more distinct than in fresher- feathered 

 examples. The rufous tinge of the under parts is very variable in shade ; 

 that of the rump, however, is always well marked. 



STATEMENTS to the effect that the Rock Wren does not 

 occur on the Pacific side have no foundation in fact. In
