FEB., 1915. NEW SOUTH AMERICAN BIRDS CORY. 299 



are whiter than in specimens from Georgetown, Guiana, and western 

 Venezuela. I have not seen specimens of 0. roraimce Salvin, which 

 from the description would seem to be nearest this form, but on account 

 of the widely separated habitat of the two forms it would be surprising 

 if they should prove to be the same. 



Speotyto cunicularia arubensis subsp. nov. 



Type from Aruba Island, Windward Islands. Adult female, No. 

 38126, Field Museum of Natural History. Collected by J. F. Ferry, 

 May 5, 1908. 



Nearest to 5. c. brachyptera Richmond, but differs in being larger and 

 in having the brown markings darker (more umber brown). Outer 

 tail feather dull white, washed slightly with pale buff on the inner web 

 and having two or three very pale brown irregular spots confined to the 

 middle of the feather; entire outer portion of the outer web white for at 

 least half of its width as well as the greater portion of the inner web; 

 buffy white markings on the middle rectrices form incomplete bars or 

 rather lateral oblong spots on each side of the shaft and do not reach 

 the edge of the webs ; the buffy whitish blotches on the basal half of the 

 outer web of the outer primary not connected as in 5. c. brachyptera; 

 front of tarsus very scantily feathered, the lower portion being almost 

 bare. Differs from 5. c. tolima in being larger, less whitish on the 

 throat, differently marked tail feathers and other characters. 



Wing, 164; tail, 75; tarsus, 45 mm. 



Average measurements of five specimens from Aruba Island: Males 

 Wing, 159; tail, 73; tarsus, 43 mm. Females Wing, 163; tail, 75; 

 tarsus, 44 mm. 



Speotyto cunicularia beckeri subsp. nov. 



Type from Sao Marcello, Rio Preto, Bahia, Brazil. Adult female, 

 No. 47130, Field Museum of Natural History. Collected by R. H. 

 Becker, March 27, 1914. 



Differs from 5. c. cunicularia from Chile in being somewhat smaller, 

 the general coloration darker and more rufous brown and the pale spots 

 on the upper parts tinged with rufous, the pale spots on the crown much 

 smaller; the bars on the under parts regular as in 5. c. cunicularia, but 

 much more rufous brown, and the white bars more or less tinged with 

 rufous; whitish spots and bars on outer primaries smaller; pale bars on 

 tail feathers decidedly rufescent; under wing coverts more tawny, and 

 front of tarsus less feathered.
