C'eutnil Aciericii (Cniateiuala, Honduras, Nicaragua, and Costa Rica). 



Althoug'h the name cyanoge7iyi< was based h\ Dr. Sharpe on what 

 was clearly an unusual development of the lighter colored triangular 

 malar patch, and is therefore misleading, it is nevertheless necessary 

 to retain it for the southern form, since it is the only one based on 

 the Central American bird. In most specimens this malar patch is 

 obsolete, sometimes quite obliterated, and in no specimen is it blue in 

 color, but dull gra3^ In none of the Central American birds is it nearly 

 so distinct as in an example of true P. mexicamis from Mirador/' State 

 of Vera Cruz, Mexico, in which it is ver}^ conspicuous, its color being- 

 clear ash grsij.
