THE GENUS CHOEDEILES SWAINSON — OBERHOLSER. 



Ill 



The difference between the gray and ochraceous phases of this 

 subspecies are not nearly so great as in Chordeiles actdipennis acuti- 

 pennis and Chordeiles acutipennis micromeris ; that is, while the gray 

 phase is practically identical in color with the corresponding phase 

 of Chordeiles acutipennis micromeris^ the ochraceous phase is not 

 nearly so deeply ochraceous nor so different from the gray phase. 

 The dark and light extremes in Chordeiles acutij^ennis inferior are, 

 however, just as strongly marked as in the other races above men- 

 tioned.
