SALVHT'S BAB.BET.

» An adult female of E. glaucogularis (one of Tschudi's original specimens, received 

 in exchange from the Museum of Neuchatel) is so closely similar to an adult female 

 identified as E. versicolor from Idma, Peru (Kalinowski, collector), that the only 

 obvious difierence consists in the slightly more bluish green of the breast.
