Carriker remarks (1. c page 858) about the Costa Rica 

 specimens of this bird, examined by him: »Costa Rican 

 skins of Tangara larvata may be separated at a glance into 

 two series, all from the Caribbean slope falling into one, and 

 those from the Pacific into the other. When compared with 

 skins from British Honduras, the Caribbean birds are found 

 to be identical with them, agreeing also with Mexican spe- 

 cimens, and must therefore be true larvata and not larvata 

 fanny, as called b}^ Mr. Ridgway. I should not say that they 

 are typical larvata, because they are not, but they are so 

 much nearer that race that they may be distinguished frotn 

 fanny at a glance. The birds doubtless intergrade in Costa 

 Rica, several skins showing a tendency in that direction.»
