NOTES ON THE GEOGRAPHICAL RACES OF 
TANGARA GYROLOIDES. 
BY OUTRAM BANGS. 
Tue blue-rumped green tanager has had, in nomenclature, a 
rather checkered career. In the present notes, I discuss Lafres- 
naye’s substitute types; describe one more subspecies; discuss 
the relationships of the form from the line of the Panama Rail- 
road; and express my opinion of Hellmayr’s treatment of the 
various geographical races. To make myself clear I must repeat 
a little of what has already been published. 
The species was originally named by Swainson (Anim. in 
Menag., 1838, 356) Aglaia peruviana, on the strength of a speci- 
men from Peru in the collection of W. Hooker. This name was 
preoccupied, and for a long time the bird has been known by the 
next name in order, not preoccupied,— Aglaia gyroloides La- 
fresnaye (Rev. Zool. 1847, 277). Before the species was divided 
by any one into subspecies, I noticed that all Colombian skins 
had green lesser wing coverts, and all from Central America, as 
well as the one or two poor specimens from Ecuador and Peru 
then available to me, had bright yellow lesser wing coverts. I 
therefore named the Colombian bird, Calospiza gyroloides 
deleticia (Proc. Biol. Soc. Washington, 1908, 160). Hellmayr
