NOTES ON BIRDS FROM WESTERN COLOMBIA. 

 BY OUTRAM BANGS. 



A short time ago I received from Mr. W. F. H. Rosenberg intact, 

 a small collection of birds made in northwestern Colombia just 

 south of Darien by one of his field collectors, Mervyn G. Palmer. 

 Although it contained but 110 species and subspecies, it is rich 

 in rare and new forms, and should future installments from Mr. 

 Palmer prove equally interesting a list of the birds of the region 

 will be published. 



While the birds of Panama and of northwestern Ecuador are 

 now fairly well known, and the ornis of the two regions presents 

 many points of affinity, strangely enough but little bird collect- 

 ing has been done in western Colombia, the link connecting the 

 two . 



Mr. Rosenberg himself did some work here thirteen years ago; 

 his bird collections, however, were small; still a few forms have 

 been named that are apparently peculiar to this general region. 



Among the better things in the present collection not specially 

 commented upon below are examples of: 



Nothocercus intercedes Salvador!. Planesticus obsoletus colombianus 



Chloronerpes gularis Har^. (Hart. & Hellmayr). 



Veniliornis dignus (Scl. & Salv.). Planesticus ignobilis goodjdluvi 



Phaethornis symatophorus syma- (Hart. A Hellmayr). 



tophorus Gould. Leucolepis dichrous (Scl. & Salv.). 



Adelomyia melanogrnyx cervina Thryophilus nigricapillus schottii 



Gould. (Baird). 



Formicarius rufipectus Salv. Chlorochrym nitidissima Scl. 



Pachyrhamphus dorsalis Scl. 1 ridornis porphyrocephala Scl. 



Following are short descriptions of a few forms that appear to 

 be new, and notes upon one or two other species:
