 were collected by Mr. R. C. McGregor (from the Pan- 

 ama birds), by Mr. J. F. Abbott (from tlic Baja Cali- 

 fornian birds) and by Messrs. Cloudsley Rutter and

 specimens or newly made skins. The determinations 

 of the Panama birds were made by Mr. Robert Ridgway, 

 curator of birds, U. S. National Museum; the determina-
