WILSONIA PUSILLA PILEOLATA (Pallas): Northern Pileolated Warbler 
Motacilla pileolata Pauuas, Zoographia Rosso-Asiatica, vol. 1, 1811, p. 497 
(Kodiak Island, Alaska). 
On November 9 I shot a male of this race in the coffee plantation 
near the house at the Hacienda Santa Maria. Other warblers of this 
eroup were seen at Puerto Limén on October 12 and at San José on 
October 15. Subspecific identity for these sight records is uncertain.

Remarks.—When Outram Bangs described acceptus* as the race 
of Myioborus from western Panamé he compared it with what he 
supposed were specimens of Baird’s aurantiacus from Costa Rica, 
noting that his birds from Chiriqui were yellower, less orange below. 
In studying the skins that I secured in the mountains of Guanacaste 
it was at once evident that there are two races of this species in Costa
