1. Hesperornis regalis Marsh. 



Of species and genera pre\dously described by me elsewhere, I iind 

 represented 



1. Palceophasianus meleagr aides Shuf. (extinct). 



Of Marsh's t^qaes belonging to the collection of the Academy of 

 Natural Sciences of Philadelphia, it may be said that: 



1. Uria affinus = a good species. 



2. Uria antiqua = a good species. 



3. Puffinus conradi = a good species. 



4. Grus haydeni = a good species. 



5. Palceotringa vetus = a limicoline bird, but not a Tringa as now 

 defined. 



All five (5) of these species are extinct, and we only know them 

 through their fossil remains, which, although sufficient, is in each case 

 very meagre. 



My study of Marsh's types in the Collection of the Peabody 

 Museum of Yale University, convinces me, in the light of additional 

 material, that they stand in need of the following revision and other 

 changes: 



1. Apatornis celer = Ichthyornis celer. 



2. Baptornis advenus = A good genus and species. 



3. Coniornis alius = Hesperornis alius. 



4. Barornis regens — Diatryma regens. 



5. Phalacrocorax idahensis = A good species. 



6. Phalacrocorax vagans = Type material too fragmentary for 

 reference. 



7. Gracidavus velox = Limosavis velox. 



8. Gracidavus pumilis = Some scolopacine species. 



9. Gracidavus anceps = Not determined from the type material. 



10. Graculavus agilis = Not determined from the type material. 



11. Graculavus lentus = Some tetraonine species. 



12. Graculavus (sp.?) 



13. Cimolopteryx rara = Some toothed species? 



14. Cimolopteryx retusus — Not determined from the type material. 



15. Laornis cdvardsianus = A good genus and species. 



16. Aletornis bellus = Tringa hellus. 



17. Aletornis gracilis = PhUohela gracilis. 



18. Aletornis nobilis = Grus nobilis. 



19. Aletornis venustus = Fulica venustus .
