Range. — Mountains of southeastern Mexico. (Monotypic.) 

 In structural characters tliis genus comes ver}' close to Yireo., the 

 bill being almost exactly as in T^ huffoni, while V. liypochryseim has 

 the wing almost equally rounded. The tail, however, is considerabh' 

 more rounded than in any species of T7/vyv, and this character, together 

 with the remarkable coloration (entirely different from that of anj^ 

 other member of the family and strongly suggesting that of PfiJogrmys)., 

 may suffice to separate the single known species generically.
