Characters. In general coloi'atiou not unlike C. t. venezuelensis, of Colombia, 

 etc., but easily recognizable by the buff shaft-streaks of the crown, mantle, foreneck, 

 and breast being laterally very distinctly edged with blackish.

Characters. Nearest to C. t. trochilirostris, but easily recognizable by its larger 

 size, much longer bill, and different coloration. The back is rich ferraginous, of 

 nearly the same colour as the rump and tail, and the under parts are bright tawny 

 ochraceons. The light markings above and .below are arranged in a similar way 

 to those of C. t. trochilirostris. Bill of the same clear red. 



Three adult males from Cnyaba . 

 Three adult females from Cuyaba, 

 One adult (the type) from Chiqnitos 

 Two yonng males from East Bolivia 

 Three males from Ocam230, Argentine . 

 Two females from Ocampo . 



Obs. Mr. Chapman separated a single unsexed specimen from Corumba 

 (Mattogrosso), on account of its larger size and fulvous coloar of the longitudinal 

 markings, from the Bolivian lafresnayamis. With six skins from Mattogrosso 

 (rufodorsalis) and three of the latter before me, I fail to see the slightest difference 

 between the two series. The former are certainly not larger, as is evident from the 

 table of measurements given above, and the cohjur of the pale markings on the 

 head and under parts is subject to seasonal variation. This is well illustrated by 

 the Cuyaba series : in a freshly moulted adult female (June 13) they are bright buff, 

 while two specimens in worn plumage have them nearly whitish. On the other 

 hand, the examples from Ocampo have decidedly longer bills, though in coloration 

 they are not different.]
