on the head, clear buff on the mantle, exactly as in eijtoni from Borba ; nnderneath 

 some are like guttatoides, while others are not distinguishable from ei/toni. In 

 the shape and colour of the bill they nearly agree with guttatoides, the upper 

 mandible being greyish horn-colour, though somewhat darker than in specimens 

 from the left bank (Humaytha, Marmellos, etc.), but not black as in eytotii. Cf.

" Iris brown, feet plumbeous, bill grey, above darker." 



Some of these specimens I have compared with the types in the Vienna 

 Museum, and found them perfectly agreeing. IK elegans is a strongly marked 

 species, not in any way to be confounded with D. insi'jnis Hellm., which has a 

 more western range. It is well characterized by having the whole back, from the 

 nape down to the chestnut rump, covered with large, pearl-shaped spots of buff, 

 and by the distinct, though narrow, buff shaft-lines or subapical dots on the lesser 

 and median, sometimes also on the greater upper wing-coverts ; the bend of the 

 wing is largely cinnamon-rnfons ; the lateral interscapular feathers are spotted with 

 buff like the back, all these pale markings being conspicuously edged with blackish ; 

 the nearly straight bill is dnsky horn-colour, yellowish towards the base of the 

 lower mandible. 



D. insignia Hellm.f has the pale markings above deeper in colour, narrower 

 and longer, more tear-shaped, and confined to the upper back ; the upper wing- 

 coverts are uniform olive-brown ; the bill decidedly curved, with the greater part 

 of the upper mandible whitish. This species ranges from Northern Peru through 

 Ecuador to Eastern Colombia. 



/). Juruana Ihering, J from the Rio Jurua, agrees with D. insignia in the 

 uniform upper wing-coverts and in the coloration of the upper parts, but the 

 wedge-shaped buff' markings of the chest are very much smaller and not extended 

 over the lower breast, and the bill is shaped and coloared as in D. elegans. I 

 am greatly indebted to Prof von Ihering for the loan of two typical specimens, an 

 adult and an immature male.
