but tbc bill of the tvpe specimen as received by me has the 

 portion remaining of the exposed culmen only .S3. The chestnut 

 color of the shafts of the rectrices does not appear to be a reliable 

 character, as these vary in a series from black to bright chestnut, 

 and some specimens have both hues, the shafts of the median 

 pair being black while those of the lateral feathers are chestnut. 

 The pale buff' of the throat is matched in the Tobago specimen 

 mentioned above, and is evidently the result of individual varia- 

 tion, the specimens being more richly colored than is seen in the 

 usual typical style. The rest of the plumage is, however, no 

 brighter in either example than can be seen in the ordinary run of 

 individual susurrans. 



JV. beauperthuysii Lafresnaye, is stated by its describer to be 

 the same as D. susurrans (vide Rev. Mag. Zool. 1S52, p. 469).

The general hue of this species beneath is rufous, occasioned by 

 the deep buff of its throat, and stripes and spots on head, back, 

 and lower parts. It is apparently confined to Guiana and is read- 

 ily distinguished from its allies, D. sus7irrans and D. nana.
