Hub. N.E. Brazil : Marco da Legoa near Pard (Princess Theresa of Bavaria). 



Characters. Differs from D. r. rujigula by its stronger, stouter bill, slightly 

 darker back, duller, more earthy brown under parts, and especially by having a row 

 of distinct, though narrow, white streaks, laterally bordered with black, running 

 along the upper margin of the ear-coverts, from the sides of the neck to above 

 the eye.

('.') D. rufigula subsp. 



Hab. North Brazil : ( 'alama, right bank of the Rio Madeira. 

 See above. More material is required to establish the status of this form ; 

 it would not be scieutitic to base a new name on a single Immature specimen. 



(f/) D. rufigula decillei (Lafr.). 



Hab. Eastern Peru : Saraya^u (Castelnau & Deville), Iquitos (Wliitely), 

 Samiria (Hauxwell). Western Brazil: Boai Lngir, Rio Purus (Snethlage) ; 

 Humaytha, Rio Madeira (Hoffmanns). 



Characters. Differs from (a) and (i6) by lacking the white longitudinal streaks 

 on the nape and sides of the neck. Moreover, the throat is uniform ochreous, 

 without any trace of white stripes ; the foreneck only shows a number of narrow buff 

 shaft-lines ; the ground-colour of breast and abdomen is much more tinged with 

 ochraceous. The bill, too, is paler, the upper mandible being light yellowish grey, 



like the lower one.
