c I have not seen specimens from either Chiapas or Guatemala, which probably 

 represent a different form, separated geographically from G. g. gnoma by the inter- 

 vening lowlands of eastern Oaxaca (Isthmus of Tehuantepec). According to Salvin 

 fmd Godman (Biol. Centr.-Am., Aves, iii, p. 36) there are color diSereuces, the value 

 of which, however, is minimized by the authors cited.
