Margarornis perlata peruviana subsp. nov. 



Type from Tambo Ventija ten miles east of Molinopampa, Peru 

 (in mountains about 30 miles northeast of Chachapoyas) . Adult male, 

 No. 44587, Field Museum of Natural History. Collected by W. H. 

 Osgood and M. P. Anderson, June 12, 1912. 



Similar to Margarornis perlata perlata but olive of crown, slightly 

 more rufous and the white markings on feathers of the under parts 

 replaced by pale yellow. White patch on throat and superciliaries 

 faintly washed with yellow. 



. Total length (skin), 150 mm.; wing, 82; tail, 81; bill, 12; tarsus, 18. 



This well marked subspecies seems to be intermediate between M . 

 perlata perlata and M. squamigera but approaches much nearer the 

 former in having the olivaceous crown very different from the rufous 

 chestnut back and the feathers of the under parts heavily bordered with 

 black. Female similar but slightly smaller. Seven specimens taken, 

 four males and three females.

Similar to M. grisea intermedia but darker; crown and back fuscous 

 brown, and black on under parts more extended; crown slightly darker 

 than the back but shading into black on the forehead; superciliary stripe 

 not extending in front of the eye. 



Apparently the darkest form of any of the races of this species.
