Ch. sp. — (J 9 OUvaceofuscus, alis cauddque eoncoloribus ; infrd,

2 $ : Uniform dark olive-brown, the wings and tail similar, unmarked; 

 below very pale sulphury-yellow, everywhere, except perhaps on the middle 

 of the belly, thickly speckled or streaked with dark olive-brown, the mark- 

 ings smallest on the throat, largest on the eidep. A long dull whitish super- 

 ciliary line. Bill and feet dark. Length, 5^-6 ; extent, 8}-9i ; wing, 2J-3 ; 

 tail, 2J; bill not over J along the culmen. 



The sexes do not differ appreciably, and the youngest birds examined are 

 not notably different from the adult ; but I have not seen the newly-fledged 

 bird. The shade of the upper parts varies from a decidedly olivaceous-brown 

 to a purer, darker bistre-browu, and that of the under parts from sulphur- 

 yellow to nearly white; but it is never of the bufly-white of S. motamlla. 

 The streaking varies in amount and intensity, but always has the sharp dis- 

 tinct character of the species in comparison with S. motacilla, and is rarely 

 if ever absent from the throat. I have seen no bill over half an inob long, 

 and this member lacks the peculiar shape, as well as size, characteristic of 

 S. motacilla. 



The earliest feathering has only lately been described, and it proves to be 

 streaky, as might have been anticipated. Mr. Eidgway speaks of a very 

 young bird as being sooty-blackish, with each feather of the upper parts 

 with terminal bar of ochraceous ; the wing-coverts tipped with the same, 

 forming two bars; the streaks below as in the adult, but broader and not so 

 sharply defined. 



It should be noted that Motacilla novehoracensis of Gm., the name currently
