Characters. In general coloration not unlike C. ¢. venezuelensis, of Colombia,

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 ferraginons, of 
nearly the same colour as the rump and tail, and the under parts are bright tawny 
ochraceous. The light markings above and below are arranged in a similar way 
to those of C. ¢. trochilirostris. Bill of the same clear red.

Obs. Mr. Chapman separated a single unsexed specimen from Coramba 
(Mattogrosso), on account of its larger size and fulvous colonr of the longitudinal 
markings, from the Bolivian lafresnayanus. 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 measnrements given above, and the colour 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. |

The type of this very distinct species still remains unique in the Vienna 
Museum. About its affinities see my remarks /.c.]
