A great diversity exists in the extent of the blue on the back in 
a series of specimens of this bird, those possessing the greater amount 
being, as is usual, the oldest individuals. In addition to a consider- 
able number of specimens from Panama, we have examined several 
from Costa Rica, the locality whence 7. venusta was originally 
obtained. All agree in every respect; hence, if 7’. venusta be of 
specific value as distinct from 7’. columbica, the Panama bird must 
be united to the Costa-Rican form.
