DESCRIPTION OF A NEW GENUS AND SPECIES OF 

 HUMMINGBIRD FROM PANAMA 



By E. W. nelson 



Since January, 191 1, Mr. E. A. Goldman, of the Biological Survey, 

 U. S. Department of Agriculture, has been detailed to the Smith- 

 sonian Biological Survey of the Panama Canal Zone to collect 

 mammals and birds in the Canal Zone and adjacent parts of Panama. 

 The most interesting discovery in his work to date has been a hum- 

 mingbird representing a beautiful new genus and species. The type 

 came from the higher slopes of the Cerro Azul, which rises to an 

 altitude of 3200 feet about 15 miles northwest of Chepo, Panama. 

 This high mountain lies at the extreme headwaters of the Chagres 

 River, and Mr. Goldman writes that it is covered with forest which 

 becomes smaller on the upper parts where these hummingbirds live. 



I am indebted to Mr. Robert Ridgway, Curator of Birds, in the 

 U. S. National Museum, for directing my attention to the marked 

 characters of this interesting hummingbird.
