 Rica, but paler and brighter green above and much paler and greener, 

 less brownish, below; upper parts between Parrot-green and Calliste- 

 green (of Ridgway); throat and chest light yellowish olive; middle

Remarks. — ^Vhile collecting for Dr. John C. Phillips in Tamaulipas, 

 F. B. Armstrong took ten specimens of this new paroquet at Altamira 

 in December, 1908. There is no variation in the series, and when laid 

 out beside a series of true E. asicc the Tamaulipas birds look almost 

 as if they represented a distinct species, so much paler and brighter 

 are they in color.
