A NEW ORTALIS FROM THE ARCHIPELAGO DE LAS 
PERLAS, BAY OF PANAMA. 
BY OUTRAM BANGS. 
WHEN I published a list of the birds collected by Mr. W. W. 
Brown, Jr., in San Miguel Island (the largest of the islands that 
form the Archipelago de las Perlas) in the Bay of Panama,’ I 
referred the two skins of Ortadis obtained by him, one in San 
Miguel, the other in Pedro Gonsales Island, to Ortadlis cinereiceps 
(Gray), which they greatly resemble in color and general appear- 
ance. Since then I have had occasion to compare these speci- 
mens more carefully with better material from the mainland than 
I then had, and am astonished to find marked structural differ- 
ences, as well as slight differences in color, that I had previously 
overlooked; the principal one is the exceedingly small foot and 
tarsus of the island bird. 
The Ortalis of the Archipelago de las Perlas may, therefore, be 
known as 
Ortalis struthopus’ sp. nov. 
Type, from San Miguel Island, Bay of Panama, ¢ adult, no. 4883, coll. of 
E. A. and O. Bangs, collected April 29, 1900, by W. W. Brown, Jr. 
Characters.— Similar to Ortalis cinereiceps, of Panama, in color pattern and 
color, but paler below, the olivaceous drab-gray of belly extending farther for-
