parts are not blacker than they are represented in Cassin's 

 figure. I may also remark that in this figure there are 

 shown some black spots on the throat. The black throat- 

 band found in the type of G. iheringi might therefore be 

 regarded as an individual character. 



" I have another specimen of Gisella (marked ? ), collected 

 by M. O. Garlepp near Cuzco (C. Peru). This differs from 

 my Santa Catharina specimen in being rather larger, in 

 having the pileum, the ear-spot, and the lores of a pure black 

 (instead of chocolate-brown), in having the back of a much 

 darker brown (nearly blackish brown in lieu of bistre-brown), 

 in presenting a blackish spot in the middle of the chin, and 

 in having much larger blackish spots at the end of the 

 plumes which form part of the lower part of the veil, also in 

 having four white bands on the tail-feathers, instead of 

 three consisting of a pair of rounded spots, as shown in the 

 Santa Catharina bird. 



" The difference in size of the two birds might be ac- 

 counted for, they being of different sexes. Unfortunately I 

 have not got specimens of true G. karrisi, Cass., which, 

 described with no certain locality, has been stated by 

 Hartlaub to have been received from Bogota (Colombia) ; but 

 I have little doubt that an actual comparison with specimens 

 from Colombia will show that G. iheringi is the same as 

 G. harrisi and that this species has a range of larger extension 

 than has been anticipated.
