Fossil Birds in the Marsh Collection oj Yale University 77 



20. Aletornis pernix = Indeterminable from the type material. 



21. Telmatornis prisons = A Rail? 



22. Telmatornis affi.nis = A Rail? 



23. Telmatornis rex = A Rail? 



24. Pala^oiringa littoralis = A Gull? 



25. Paloeotringa vagans = Type material too fragmentary for a cor- 

 rect reference. 



26. Grns haydeni = A good species. 



27. Grus proavus = Not seen (lost?). 



28. Uintornis lucaris = Awaiting additional material. 



29. Aquila dananus = Good species (?) (provisional). 



30. Bubo leptosieus = Not a Bubo. Awaiting additional material. 

 All of these birds are extinct. 



Through the study of much additional material, the following 

 change becomes necessary and is proposed: 



I. Aquila antiqua Shuf. = Minerva antiqua Shuf. 



I find the material in this Yale University Collection to estabhsh 

 the following new genera and species, each and all of which are now 

 extinct : 



1. Colymbus oligoceanus. 



2. Gavia pusilla. 



3. Larus pristinus. 



4. Stda atlantica. 



5. Phalacrocorax mediterraneus. 



6. Phalacrocorax marinavis. 



7. Eoceornis ar delta. 



8. Botauroides parvus. 



9. Grus marshi. 



10. Limicolavis pluvianella. 



II. Colinus eatoni. 



12. Tympanuchus hdli. 



13. Phasianus mioceanus. 



14. Phasianus alfhUdce. 



15. Phasianus americanus. 



16. Meleagris richmondi. 



17. Falco Jalconella. 



From the list, and from what has been set forth on previous pages of 

 the present article, it will be observed that, in so far as the new genera 

 and species here described supplement those of previous works in the 

 same field, and covering geologic ages between the middle Eocene 

 (Bridger Beds) to include Post Pliocene time, the greatest number of
