Hypothetical List. 



Since there are a few records of birds in Wyoming that 

 have not been satisfactorily disposed of, it has been deemed 

 advisable to place them in a hypothetical list. These data were 

 prepared for the regular list and have been transferred as 

 written. 



204. Grus americanus (Linn.). 

 Whooping Crane. 

 Reported by C. E. Aiken, 1872: but lacks confirmation. 



212. Rallus virginianus Linn. 

 Virginia Rail. 

 Reported by C. E. Aiken, 1872 ; but lacks confirmation. 



465. Empidonax virescens (Vieill.). 

 Green-crested Flycatcher. 



Accidental, if it is entitled to a place in the Wyoming 

 fauna. The only record is that of Drexel who reported it 

 from Fort Bridger in 1858. 



474 a. Otocoris alpestris leucolaema (CouES.). 

 Pallid Horned Lark. 



There are numerous records referring to this variety as 

 occurring in Wyoming. I have endeavored to confirm the 

 evidence offered ; but have been wholly unable to locate a single 

 skin or specimen that has been taken. On this account it has 

 been placed in this list and further investigations as to its west- 

 ern range are very desirable. 



478. Cyanocitta stelleri (Gmel.). 

 Steller's Jay. 



Rare or accidental. The only possible record of this 

 bird being taken in Wyoming comes from the National Muse-
