408 Chapman, The Genus Scytalopus Gould. ■ [oct. 



of S. niger, sent by the same collector, permits me satisfactorily to 

 determine our large series of the last-named species. 



An examination of Lafresnaye's "Bogota" types was of course 

 indispensable in this connection. These Mr. Bangs has kindly 

 loaned me as well as the twenty-one other specimens of the genus 

 contained in the Museum of Comparative Zoology. 



The results of my studies of all this material, in so far as they 

 affect the status of the species found north of the equator, may be 

 summarized as follows. 



Scytalopus senilis (Lafr.) = Myornis (gen. nov.) senilis (Lafr.). 



Scytalopus magellanicus Auct. nee Gmel. = Scytalopus niger 

 Swains. 



Scytalopus analis Auct. nee Lafr. = Scytalopus micropterus mi- 

 cropterus Scl. 



Scytalopus analis (Lafr.) = Triptorhinus paradoxus Kittl. 



Scytalopus latebricola Allen nee Bangs = Scytalopus sanctoe- 

 martce Chapm. 



Scytalopus sylvestris Bangs nee Tacz. = Scytalopus sanctce-martos 

 Chapm. 



The following four species are described as new : 



Scytalopus panamensis (Subtropical Zone, Tacarcuna, E. Pan- 

 ama). 



Scytalopus canus (Temperate Zone, Paramillo, West Andes, Col.). 



Scytalopus sanctce-martoe (Subtropical Zone, Santa Marta Mts., 

 Col.). 



Scytalopus infasciatus (Temperate Zone, Eastern Andes, near 

 Bogota). ' 



Since the status of all but two 1 of the species known from north 

 of the equator is affected by this revision I have for the sake of com- 

 pleteness added notes on them. 



In addition to the species herein treated the following species 

 from south of the equator are currently recognized; but in view of 

 our discoveries in Colombia, it seems probable that our knowledge 

 of the forms of Scytalopus from south of that country is far from 

 complete: 



Scytalopus magellanicus (Gmel.). Falkland Islands, Cape Horn 

 region and northward into Chile. 



1 S. griseicollis (Lafr.); S. argenlifrons Ridgw.
