nppor wing-rovevts, ai)fl in having tlie forpnerk anil breast marked witli broad, 

 ol)lor)g spots of buff. Moreover, there is hardly any nifeseent tinge on the bend 

 of the wing. The shape of the bill is exactly alike in the two species. D. spixii 

 ranges from ParA westwards to Santarem, right bank of the Rio Tapajoz. Thanks 

 to the kindness of Dr. Charles W. Richmond, I have been enabled to examine the 

 type of D. /raterc'/liis Riigw.* and found it identical with Pani examples. On 

 the left bank of the Rio Tapajoz, however, f>. elei/a/is is met with, for Miss 

 Snethlage has lately obtained a specimen at Villa Braga (Journ. /. Oni. 19U8. 

 p. 508). 



The range of D. elegans is thus as follows : 



Right bank of the Rio Madeira: Calama, Allianca; Marnins, Rio Machados 

 (Hoffmanns); Engenho do Gama, Rio Gnapore (Natterer). Left bank of the 

 Rio Tapajoz : Villa Braga (Snethlage). 



Although I expect that D. elegatis, I), juniana, D. spi.vii, and D. insignis 

 will prove to be geographical modifications of a single species, it would be unwise 

 to use trinomials until their relations are better understood. L>. pardalotiis 

 (Vieill.), from the Guianas, Orinoco region, and Rio Negro, appears also to belong 

 to this group.

Natterer obtained a good series near Borba, lower Rio Madeira. The 

 specimens are practically identical with Spix's type in the Munich Mnsenm. 

 Though agreeing in shape and colour of bill, I), ocellata undoubtedly is specifically 

 distinct from D. elegans and its allies. The uniform brown back, with hardly a 

 few, hair-like buff shaft-lines on the nape and adjoining portion of the upper mantle, 

 serves, together with other characters, to distinguish it at first sight.]

vSpecimens from the Rio Madeira (Calama, Borba) agree perfectly with the types 

 from Fonteboa. The original example of D. obsoletus said to be from " Para " 

 differs by the pale stripes on the mantle being not or very indistinctly bordered 

 with dusky. Until more specimens with definite localities come to hand it 

 cannot be said with certainty whether this character is of any value. Miss Snethlage t 

 has lately recorded D. obsoleta, from the Tapajoz and Tocantins Rivers, unfortunately 

 without any further comment.
