NORTH AMKRICAN BIRDS. 



A s])ccimen frnin Santa Clara, California (4,47"), Dr. J. (1. Cooper), like 

 most of tlioso from the Pacific coast, has tlic cinereous very dark aliove, wliile 

 boneatli tlie ochraceoiis is cverywliere prevalent ; tlie flanks are stvonyly 

 tiii;4cd with blue; the black bars of the tail arc nmch broken anil irreyular. 

 A si)ecinieii from Jamaica {24,'M)\), Spanish Town ; W. T. Alarch), however, 

 is even darker than this one, the stripes beneath lieinj,' almost jiure liku'k ; 

 on the tail l)lack jirevails, although the bands are very regulnr. Nos. 1I7,<>01, 

 Fort Good Hope, British America, 4;>,1;^>G, Fort Yukon, Alaska, and al.MOu, 

 Mazatlan, ^le.xico, have the streaks lieneath narrow and linear ; the ochra- 

 ceous coufiued to the tibia?, which are of a deejj shade of this color. 



Falrn ciilumharius. 



A specimen from Xicaragua (No. 40,957, Chiiiandega) is like North 

 American examples, but the reddish tinge beneath is scarcely discernible, 

 and confined to the tibia', which are but faintly ochraceous ; the markings 

 beneath arc broad and deep umber, the black shaft-streak distinct. 



In the adult female there is as little variation as in the male in plumage, 

 the shade of brown above varying slightly, also the yellowish tinge beneath ; 

 the bai's on the tail ditt'er in continuity and tint in various specimens, 

 although they are always five in num.ber, — the fir.st concealed by the coverts, 

 the last terminal. In 19,.382, Fort Simpson, British America, and 2,7U0, 

 Yukon, If. Am. ([)roiiably very old bird.s), the light bars are contimious and 

 pale dull ashy. 



The young vary about the same as adults. Nos. 19,381, 15ig Island, (5reat 

 Slave Lake ; 5,483, Petaluma, California ; and 3,700, Kacine, Wisconsin, —
