Museum) are slightly intermediate between tombacea and cyanescens, the smoky 
brown feathers of the forehead being narrowly edged with green or bluish green. 
As pointed out by me (/.c. p. 402), the Humaytha birds have a larger, more 
whitish chin-spot than the Peruvian ones. However, it is well to remark that 
this character is subject to much individual variation in the northern G. ¢. 
tombacea. |

These specimens agree perfectly with several from Pari, while those préviously 
obtained by Mr. Hoffmanns near Humaytha (left bank) had the cheeks and malar 
region golden green (instead of blue). Cf., however, the remarks by Miss Snethlage 
in Journ. f. Ornith. 1908. p. 20. 
G. cyanicollis ranges from Pard westwards to the Jurud and Puris Rivers.

The two skins from this locality in the Vienna Museum agree perfectly with 
others from Guiana. G. ¢. leucogastra ranges from French Guiana westwards to 
the upper Rio Negro (Guia, Marabitanas), and southwards to Borba, on the Lower 
Madeira. An adult male from Marabitanas, belonging to the Vienna Museum, 
has a larger bill and slightly more coppery suffusion both on back and breast, 
pointing towards G. /. chalcothorax Scl.* Typical specimens of the latter, however, 
may be recognized by their longer wings and nearly uniform copper-red back and 
breast. There are several examples from the Rio Napo in the Manich Museum. }
