Perhaps rare, but a single specimen having been secured at Iron Springs, 

 Utah, October 4. Not recorded before from so far west. It is by no means 

 certain that the occurrence of this snowbird here is merely accidental. The 

 specimen obtained was shot from among a flock of the Junco oregowus, 

 which was exceedingly numerous ; and, its true identity not being known 

 at the time, I took no pains to ascertain its relative numbers as compared 

 with orcgonus. It may occur during the migrations regularly.

Tins race of the common snowbird (hyemalis) is found late in the fall 

 and winter, distributed over quite a, large area in the middle Rocky Mount-
