Remarks— In my paper on Underwood’s collection from the 
Boruca region of southwestern Costa Rica’ I referred the long- 
tailed finches he took to the recently described Emberizoides 
sphenura hypochondriacus (Hellmayr) of Chiriqui. Afterward, not 
being able to reconcile my specimens with Hellmayr’s description, 
I sent them to him and he most kindly compared them with the 
original seven skins at the Tring Museum. He subsequently 
wrote me that the two lots of skins represented quite distinct forms, 
carefully pointing out the differences. 
The Costa Rican form of E. sphenwra is the darkest of all the 
races, on fore neck and chest, the intensity of the color of these 
parts being unequalled among the other subspecies.
