AUGUST, 1916. NEW SOUTH AMERICAN BIRDS CORY. 339 



Although the coloration of the throat would indicate immaturity, 

 I can not refer this bird to any described form. The general coloration 

 is much more slate color than any of the allied species. The longer 

 wing and grayer coloration will distinguish it at once from approximans, 

 tyrannina, sclateri, etc. 



The female has the throat whitish mottled with dusky, in this 

 approaching carbonaria, but the belly is buffy ochraceous and much 

 paler than in tyrannina. 



Female: Wing, 71; tail, 53 mm. 



Myrmeci/a berlepschi peruviana subsp. nov. 



Type from Yane Yacu, near Yurimaguas, Peru. Adult male, No. 

 49121, Field Museum of Natural History. Collected by M. P. Ander- 

 son, September 9, 1912. 



Similar to M. b. berlepschi Ridgway from Chimbo, N. W. Ecuador, 

 but larger; wing longer, and bill heavier. It also differs in having much 

 less white on the bend of the wing. 



Wing, 92; tail, 67; bill, 22; tarsus, 30 mm. 



Compared with the type of M. b. berlepschi preserved in the U. S. 

 National Museum. 



Furnarius leucopus cearae subsp. nov. 



Type from Quixada, Ceara, Brazil. Adult male, No. 49120, Field 

 Museum of Natural History. Collected by R. H. Becker, June 27, 1913. 



General coloration approaching F. I. assimilis and the rufous 

 markings on the primaries about the same; but differs in having the 

 entire upper mandible dark brown; the crown of the head sepia brown 

 (approaching that of F. I. leucopus), with the forehead showing a tinge 

 of rufous. Back, rump, and tail approaching assimilis in coloration, 

 but slightly more orange brown; middle of abdomen and exposed under 

 tail coverts purer white; the basal portion of the larger under tail 

 coverts brownish black, not distinctly brown as in assimilis; legs and 

 feet pale. 



Wing, 93; tail, 65; oilmen, 19; tarsus, 23 mm. 



Two specimens of this subspecies were also taken at Serra Baturite', 

 Ceara, Brazil, by Mr. Becker. 



Schizoeaca fuliginosa peruviana subsp. nov. 



Type from mountains east of Balsas, Peru (alt. 10,000 feet). Adult 

 male, No. 47677, Field Museum of Natural History. Collected by
