LETTER OF TRANSMITTAL 



Department of the Interior, 

 United States Geological Survey, 



Washington, D. C, May 26, 1899. 

 Sir: I have the honor to transmit herewith a manuscript entitled The 

 Eocene and Lower Oligocene Coral Famias of the United States, with 

 Descriptions of a Few Doubtfully Cretaceous Species, and to request that 

 it be published as a monograph of the Survey. My study of these faunas 

 was begun before my association with the Survey, but has been completed 

 since my assignment as assistant to Dr. Wm. H. Dall, in the Division of 

 Cenozoic Invertebrate Paleontology. My special thanks are due to Dr. Dall 

 for his encouragement of this work. 



Very respectfully, T. Wayland Vaughan, 



Assistant Geologist. 

 Hon. Charles D. Walcott, 



Director United States Geological Survey.
