 5.50, average 5.00, always longer than wing; bill about 1.00. Florida (and Gulf States?), 

 abundant. Very local, and not authentic as occurring outside of Florida. Usual habits of 

 jays. Nest a flat structure, in bushes, of twigs lined with fibres. Eggs 4-5, bluish-green,

355. A. f . wooahou'sU, (To S. W. Woodhouse.) Woodhouse's Jay. The dorsal patch dark, 

 glossed with blue, shading into the blue of .surrounding parts ; under parts rather darker than 

 in C. floridana, somewhat bluish-gray ; the under tail-coverts bluish but not contrasted ; on 

 the breast the blue and gray shading into each other, the gular and pectoral streaks whitish

 nearly white). Chin, throat, and breast with a series of whitish blue-edged streaks, enclosed 

 in surrounding blue. Lores, orbits, and auriculars dusky. A series of sharp white streaks 

 over and behind eye. Wings and tail blue ; the inner webs of most of the quills, and the tail 

 viewed from below, dusky. The inner secondaries and tail-feathers, closely examined, show 

 obsolete barring, like that which becomes pronounced in Cyanocitta, but the traces are faint, 

 and the feathers may be properly called plain. Iris brown ; bill and feet black. Length of <? , 

 about 12.00: extent 16.50; vring5.00; tail 6.00; bill 1.12 ; tarsus 1.50; middle toe and claw

 pectoral streaks undefined, as are those over the eye. Eocky Mt. region, from Wyoming and
