STRIX VARIA ALLENI (Ridgway). 



FLORIDA BARRED OWL. 



Similar in coloration to S. v. varia but toes wholly naked, except 

 a narrow strip on outer side of middle toe.*^ 



Adult male.— Length (skins), 410-492 (460); wing, 315-340 (326.5); 

 tail, 205-231 (220.4); culmen, from cere, 23-28 (24.8).^ 



a After carefully comparing a large series of specimens I am unable to find any 

 average color difference between this form and S. v. varia, 

 & Twelve specimens.
