 from Caicara. Field work and a study of the larger series of specimens 

 in this museum, together with material from the American Museum of 

 Natural History and from the U. S. National Museum, has convinced

 Cathartes found along the shores of the Orinoco. I have not had access, 

 however, to sufficient authentic material, material with reliable data, 

 to work out the relationship to my own satisfaction. I brought back 

 with me eleven specimens, representing two quite distinct and well . 

 marked species, both of which are resident in the region under con- 

 sideration and are distinguished by the native Venezuelans who call 

 them respectively Zamuro Oripopo de Cabeza Colorado and Zamuro
