The Status of Aphelocoma cyanotis and its Allies. By Harry C. Ober- 
holser.— After studying a large series of these Jays Dr. Oberholser finds 
that A. cyanotis does not occur within the boundaries of Texas, specimens 
so identified proving to be texana, and it must therefore be eliminated from 
the A. O. U. Check-List. Furthermore he finds that with the exception 
of the Florida Jay (A. cyanea), and A. insularis from Santa Cruz Island, 
all the forms intergrade and must therefore be rated as subspecies of A. 
californica. A. c. immanis Grinnell he regards as a recognizable race.
