This series, which is to be considered topot_vi)ital, does not differ iu any way 

 from C'aura e.\ample<. In the malos, the slate-grey of the flanks is separated by a 

 distinct white strijie fmm the rosy red colour of tlie belly, forehead and crown are 

 glossy black, and behind the eye there is a broad, lengthened stripe of white. The 

 distinctness of G. p. paraensis Rothsch.* is thus fully confirmed. The range of the 

 two forms is as follows : — 



(a) G. p. pelzelni Sol. 



North Bolivia : Falls of the Madeira (Rusby).t North Brazil : Destacameuto 

 do Ribeirao, Salto do Girao (Natterer), Borba, Calama (Hoffmanns), on the Rio 

 Madeira; Jamarysinho, Rio Machados (Hoffmanns); Itaitiiba (Hoffmanns, J 

 Snethlage§), Villa Braga (Snethlage §), Hio Tapajoz ; Arnraathena, left bank 

 of Tocantins (Snethlage li). British Gniana : Camacnsa (H. Whitely, jun. 1). 

 Venezuela**: Mnuduapo, Orinoco (Cherrie) ; Suapure (Klages), La Priciou. 

 La Union, Nicare (.\ndre), Canra River.

The differences noticed between topotypical Para specimens and those from 

 more westerly localities (/ r.) do not prove to be constant. The adult cf is practically 

 identical with several skius from Pani. 



The young bird, whose back is still partly covered with the flufl'y, brownish 

 feathers of the nestling plnmage, has the bill mnch shorter, narrower, and entirely 

 black (instead of pale brown). The rectrices, too, are longer, distinctly pointed, and 

 interiorily edged with pale yellowish.
