Twenty-six specimens : Tucurinca and Fundacion. 



Ccrcomacra nigricans was described by Sclater from a supposed 

 Santa Marta specimen received from Verreaux, but until the present 

 series was collected no one else had ever succeeded in finding it in this 

 region, although meanwhile it had been traced westward to Panama 

 and eastward to the Orinoco Valley. Sclater's type was an adult fe- 

 male, and two pages later he described the adult male as a member of 

 a different genus, calling it Pyriglcna macidicaudis. The present 

 series includes a goodly number of immature birds, readily distin- 

 guishable by their brown wings (with the middle and greater coverts 

 plain), paler color above, and gray and white squamations betow. 

 Several of these show moult of the remiges, rectrices, and body-plum- 

 age going on (September 20-October 19). 



This Tropical Zone' form is evidently confined in this region to the 

 Magdalena basin, extending eastward to the edge of the alluvial plain, 

 but scarcely entering the foothills. It is found in the more tangled 

 parts of the heavy forest, always in pairs, keeping near the ground.
