Patagona gigas peruviana BOUCARD: Peruvian specimens average decidedly 

 larger than those from Chile. Attention has been called to the deeper rufous colora- 

 tion of the under parts, but which does not seem to be constant, the chief difference 

 being one of size. 



b Prof. Ridgway considers that chionogaster (TSCHUDI), pallidus Taczanowski 

 and viridicauda SCLATER and SALVIN, should be excluded from this genus and 

 placed in the Genus Talaphorus MULSANT (cf. Bull. U. S. Nat. Mus. No. 50, 

 V, 1911, p. 305, footnote).
