Euphonia crassirostris is smaller than E. laniirostris, to which 

 it has often been referred, and the adult males are much less 

 deeply colored throughout, especially below, where the yellow is 

 a light clear yellow and not the deep, almost gamboge yellow of 

 E. laniirostris. There is a corresponding difference in the olive 

 green of the young males and females. (See further on this 

 point, this ' Bulletin,' Vol. Ill, 1891, p. 351.)
