species, is immature, the remiges and rectrices being prominently 

 edged with cinnamon. 



Simons secured a specimen of this species (erroneously referred at 

 the time to M. tyrannidus) in the immediate vicinity of Santa Marta. 

 It occurs throughout the lowlands around this locality, and perhaps 

 even more commonly on the west side of the Sierra Nevada, but not 

 going above 1,000 feet. We have seen it at Valencia, in the Rio Cesar 

 Valley. Like many others of the genus, it prefers open country, scat- 

 tered trees and shrubbery.

Twenty-three specimens : Bonda, Cautilito, Mamatoco, Rio Hacha, 

 Fundacion, and La Tigrera. 



A single topotypical Cayenne specimen is matched very closely by 

 certain of the above series, but most of the specimens are a little 

 grayer above. From the material studied in this connection it appears 

 very doubtful if this species can be divided into recognizable geo- 

 graphic races, aside, of course, from the Brazilian form (bahice). 

 At any rate the forms described from Curasao and Matto Grosso are 

 certainly not separable. 



Two specimens from Mamatoco, September 1 and 2, are in postnup- 

 tial moult, renewing the remiges and rectrices. In another specimen 

 from the same locality, dated April 26, the cinnamon area on the outer 

 rectrix is much reduced in width, and not sharply defined from the 

 dusky part. 



This species occurs only in the lowlands and lower foothills, scarcely 

 passing the 1,000-foot limit. It is less abundant than M. ferox pana- 

 mensis, although found under about the same conditions. 



The nest is built in hollow trees, just as in the case of M. crinitus. 

 Of two nests sent in by Mr. Smith, one was "in situ in the hollow 

 hollow stump of a dead stub, about one foot below the top of the
