neck, wings, and tail bright olive-green, edge of wing yellow, chin 

 and abdomen white. 

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

 In structural characters this genus comes very close to Yireo, the 

 bill being almost exactly as in V. huttoni, while V. hypochryseus has 

 the wing almost equally rounded. The tail, however, is considerably 

 more rounded than in any species of Yireo., and this character, together 

 with the remarkable coloration (entirely different from that of any 

 other member of the family and strongly suggesting that of Ptilogonys), 

 may suffice to separate the single known species generically. ,
