Platyrhynchus mystaceus, YieiW. N. Diet, d'Hist. N. xxvii. 

 p. 14; Scl. Cat. Am. B. p. 207. 



Roraima (3500-6000 ft.). 



These birds agree with Brazilian examples which I believe 

 to be P. tnystaceus, Vieill. A male specimen has the man- 

 dible dark-coloured and thus differs from females, which have 

 a pale yellow mandible. The difference is probably due to 

 the immatiirity of the former. 



153. Platyrhynchus saturatus. 



Platyrhynchus saturatus, Salv. & Godm. Ibis, 1882, p. 78. 

 Camacusa, Merumd Mountains. 



154. Platyrhynchus superciliaris. 

 Platyrhynchus superciliaris, Lawr. Ibis, 1803, p. 184. 

 Bartica Grove. 



Besides Mr. Whitely^s examples we have two others from 

 Albina in Surinam, obtained in 1866 by Mr. Clarence 

 Bartlett. These are, in my opinion, undistinguishable from 

 Panama specimens of P. s?iperciliaris, Lawr. The most 

 nearly allied species is P. coronatus, Scl., of Eastern Ecuador, 

 a somewhat larger darker bird with less clearly defined yellow 

 colour beneath. 



155. TODIROSTRUM CINEREUM. 



Todus cinereus, Linn. Syst. Nat. i. p. 178.

Todus muculatus, Desmarest, Tod. pi. 70. 



Todirostrum maculatum, Scl. & Salv. Ibis, 1881, p. 267. 



Bartica (xrove. 



This is the true T. maculatum, as distinguished from the bird 

 of the Amazons valley, the T. signatum of Sclater and Salvin 

 Ibis, 1881, p. 267. 



157. Euscarthjmus russatus. 



Euscarthmus russatus, Salv. & Godm. Ibis, 1881, p. 445.
