JAN. 1917. NOTES ON SOUTH AMERICAN BIRDS CORY. 7 



Similar to S. s. squammata from Bahia, with bases of outer webs of 

 outer primaries without rufous, but breast and throat paler and shading 

 to white on upper throat; chin pure white. 



Wing, 95; tail, 103; bill, 12 mm. 



Scardafella r. brasiliensis Beebe (Zoologica, I, No. i, 1907, p. 21) 

 comes very close to being a nomen midum, although he had but one 

 Brazilian specimen (from Bahia) and scattered throughout the paper 

 are various references to it, including measurements (in the table of 

 measurements) and a plate, but luckily the question of nomenclature 

 is not important, as the supposed type being from Bahia the name is 

 antedated by 5. squammata squammata (Lesson). 



Leptoptila ochroptera approximans subsp. nov. 



Type from Serra Baturite, Ceara, Brazil. Female, No. 46922, 

 Field Museum of Natural History. Collected by R. H. Becker, 

 July 19, 1913. 



Similar to L. o. ochroptera of southern and eastern Brazil, but 

 differs chiefly in its much more pale brown (almost vinaceous brown 

 and not at all olive) back, rump, and upper tail coverts. Size about 

 that of females of L. o. ochroptera. 



Piaya cayana venczuelensis Cory* 



This form is apparently restricted to the low heavily forested 

 region south of Lake Maracaibo in western Venezuela, and is readily 

 distinguished from P. c. columbiana by its chestnut bay upper parts 

 and generally darker coloration and from P. C. cayana by the conspicu- 

 ous rusty brown coloration on the under surface of the rectrices and 

 other differences. 



|-'$ Reference to the difference in coloration of the under surface of 

 the rectrices was inadvertently omitted in my original description of 

 the subspecies when comparing it with P. c. cayana. 



* Described in Field Mus. Pub., No. 167, Orn. Ser. I, 1913, p. 284 (Orope, 

 Venezuela).
