Voniii/ malt' (•"i,581, Medicine How ("reek, Xeliraska, Anjrnst 7, 1850; \V. S. Wood). 

 J'ixaelly like the adiilt male, lull with the rnlbns darker, api)roachinf; to eheslmit; spots 

 beneath inclining; to a tear-shaped Ibrm, and, thony'li more immeions. are not so well 

 dclined as in the adnlt ; also riilesceiit tiiiire beneath more jreneral ; bhie of the wind's with 

 scai-ecly any spots; white lermimil band of tail t:ii<red with rnlons. Sometimes the two 

 or threi' outer leathers are elouded with .ish, and possess inilieation of bais, formed of

YniiDf) Jhiinh (HV'2t1, Fort Rice, Uacota ; 8. M. Rothhannner). Generally like the 

 adult, but with rnlbiih ■''"■-.e darker, ai)pioaehiiip; ferruginous; the bars everywhere 

 broader, and purer black; rufous vertical patch .streaked centrally with black ; spots 

 beneath larger, darker, approaching reddish umber. 



II.M!. Continental North America (only), across to both coasts, and from Arctic 

 regions to Isthmus of ranama; not in West Indies. 



This form ranges over tlio M'liolo of continental Xorth America, from 

 Paniima nortliwiird into tlio llritish "mvinccs, iiml from the Athmtic to tlie 

 rticific. Tlirongliont tlie Avhttlt; of this extensive area tlie binl exliibits 

 very little variation, in fact, none not of an almost individual cliaractcr, 

 consisting mainly in tlio varying amount of ashy-wliito and hhick on the 

 lateral tail-feat he, and also, to a less extent, in the depth of tlie ochraceous 

 tint on the lireast, and tlie ahmiilance and .size of the black spots on tlic 

 sides or lltinks. In the (Utlf region of tlie Unit(>d States it ]iasses gradually 

 into var. isKhtl/iui'S through intermediate specimens. We liave setni Fhnida 

 .skins (kindly lent to us by ^Fr. -I. A. Allen) from Mitimi ((? , danuary L".», 

 1872), Cedar Keys («?, Februtiry 2.S, 1S71), and Florida Keys (c?, February 

 14, 1871). Of these, only the lirst (No. U,4',ir) deviates noticealdy from tlie 

 tyjiiciil style; it inclines toward var. Uilirlliait^ in sjiarsity of black spots on 

 flanks and restricted riii'oiis on the down, but in tht! pure light ash of the 

 crown iiiid wings, and flint ochraceous of the breast, it resembles more the 

 \i\r. spiinrriHs. 'Wing, (l..">() ; tail, 4.7IK The two other sju'cimens nK'asure 

 its folh.v.-s: Xo. 14,487, Florida Keys, wing, (i.'.IO ; tail, r..!M). No. 14,4'J2, 

 Cedar Keys, M-ing, (i.iiO; tail, .-i.OO. The former is peculiar in having some 

 of the up])er tail-coverts either ])artly or entirely ashy. 



]\Fexican .s]iecimens represent the race in the greatest imrity or exaggera- 

 tion of its characteristic features, in jmre and light bluish-ash of wings uid 

 crown, greatest extent of rufous on crown, etc. ('alifornia specimens often 

 cxhiliit what I havtf not noticed in eastern examples, though possibly 

 ncciirring in them; that is, in adtdt males the cere and feet are of a deep 

 orange-red — almost vermilion color.
