Apart from the five type specimens of extinct birds described by 

 Professor Marsh, and which I borrowed from the Academy of Natural 

 Sciences of Philadelphia for examination and comparison with new 

 material, all the figures herein described and referred were, for the 

 most part, collected either by Professor Marsh himself in the field or 

 by some of his collectors. In a few instances, they were presented to 

 him or to the collections of Yale University. At his death, the entire 

 collection became the property of the Peabody Museum of Yale, 

 where it is deposited at the present time. 



Many of these specimens have remained in the Museum for years 

 unworked and undescribed; some are still in their original receptacles, 

 w^hile several of them were collected as early as the 70's, and many of 

 them only a few years thereafter. 



When submitted to me for revision and description, as pointed out 

 in the first part of this paper, there were 136 lots of these fossils, num- 

 bering, all told, some 400 specimens or more. Of these about 83 

 came from Wyoming, and are found to be principally Ft. Bridger 

 Eocene forms; 16 from New Jersey; 2 from New Mexico; 7 from Kan- 

 sas; 4 from Nebraska; 8 from Oregon; 2 from Texas; 3 from Colorado; 

 California 2; Idaho 1; Virginia 1 and Montana 1, thus leaving six not 

 definitely fixed. 



As I have just stated, most of these fossils came from the Ft. 

 Bridger Eocene formation, while some 24 are from the Cretaceous; 11 

 from the Oligocene formation; 6 from the Miocene; 9 from the Post 

 Pliocene, and one from the "Post Tertiarv."
