Chamaeza turdina chionogastbe, subsp, nov. 



c? Nearest to G. t. turdina (Cab. & Heine) from Bogota, 

 but easily recognisable by its stronger and longer bill, by 

 the pure white ground-colour of the under-parts without 

 any fulvous tinge on the f oreneck and sides, and by having 

 the three outer pairs of tail-feathers narrowly fringed with 

 white at the tip. The upper-parts, too, are rather lighter 

 rufescent-brown, and the tail is much paler, dark-brown 

 with the outer webs but slightly washed with ruf escent, 

 instead of being uniformly dark russet-brown. In the 

 white ground-colour of the under-parts the new form agrees 

 with G. nohilis, Grould, of Eastern Ecuador and N.E. Peru, 

 but this bird has a distinct ferruginous supra-loral streak, 

 and all the rectrices, except the middle pair, have a broad 

 black subterminal band, followed by a narrow whitish 

 apical margin. Wing 91-5, tail 70, bill 19-3 mm.

(^ Differs from all the other Giant Ouzels of the Andes 

 in its much darker, uniformly blackish coloration, only a 

 few feathers on the upper back and breast showing very 

 slight brownish edges. The axillaries and under-wing 

 coverts are blackish like the rest of the plumage, and there 

 is no trace of the whitish chin-spot, always to be seen in 

 T.f.fuscater and T.f.gigas. Wing 150, tail 139, bill 

 29 mm.
