Top of head and nape blackish, each feather with a lengthened central 

 buffy white spot. Back bright olive, with a few narrow bufty white lines 

 on the upper part. Upper tail-coverts cinnamon. Throat yellowish white, 

 varying in depth of shade, each feather with an apical blackish brown 

 margin. Entire underparts dark olive thickly covered with yellowish 

 white triangular spots placed at the end of each feather. In some 

 specimens these spots are rounded at the end instead of being of a trian- 

 gular shape. Wings pale cinnamon, with the edges of the outer webs of 

 all the feathers bright olive. Tail dark cinnamon brown. Bill blackish 

 at the base, yellowish white for the remaining part. Feet, olive brown. 

 Total length, 8| inches. ; wing, \\ in. ; tail, 4^ in. ; bill, ij in. This 

 description is from the type specimen, No. 2276, Coll. Bost. Soc. Nat. Hist 

 Other specimens vary in their measurements as follows: Wing, 4^ to 

 4^ in. ; tail, 4§ to 4$ in. ; bill, i£ to i£ in. 



There are three types of this species from the Lafresnaye col- 

 lection before me, two of which are D. triangularis, and the 

 third is D. erythropygia Sclat. Whether this last came from 

 Colombia with the others, I have no means of ascertaining-, as no 

 locality was given upon any of Lafresnaye's types. That author 

 evidently did not perceive that he had two allied species in his 

 possession. There is no doubt, however, which of the three 

 specimens Lafresnaye considered as triangularis, as ids des- 

 cription and figure, poor as the latter is, point conclusively to the 

 bird without the cinnamon rump, and with the throat feathers 

 margined with a dark line and not spotted.
