 Pima Villages, Southern Arizona, Heermann. Probably not to be found as 

 high up as Fort Whipple, being restricted to the Gila and Lower Colorado 

 Valleys. 



MOTACILLIDM. 



6. Anthcs ludovicianus Licht. 



Abundant. Winter resident. Arrives late in the autumn, according to 

 weather, and remains until May. None breed in the vicinity of Fort Whipple. 



DACNID^E. 



(87.) Certhiola flaveola (L.) Sund. 



This species, first introduced into the United States Fauna by specimens 

 from Indian Key, Florida, has since been found abundantly at Matamoras and 

 Brownsville, Texas, and also at Cape St. Lucas. It ranges over the interme- 

 diate ground along the Southern border of the Territory.

Description. (Orig. No. 1293, rj\ Apr. 26, 1865, Fort Whipple.) Bill shorter 

 than head or tarsus, about equal to the middle toe without its claw ; the cul- 

 men convex, the gonys very slightly so, the commissure a little curved. 

 Wings of ordinary length for this genus ; second and third primaries about 

 equal and longest ; first and fourth about equal to each other, and but little 

 less than the second or third. Sometimes the first four hardly differ appreci- 

 ably in length. Fifth -20 of an inch shorter than fourth. Tail of ordinary 

 length ; a little rounded, the outer lateral rectrices being a tenth of an inch 

 less than the median pair. Tarsus a little longer than the middle toe and claw. 

 Lateral toes short, equalling each other in length : the tips of their claws fall- 

 ing short of the base of the middle claw. Hind claw much longer and mor 

 curved than the others ; about as long as its digit. 



Adult spring plumage. Entire upper parts ashy gray, with a tinge of blui-h 

 slate; the interscapular feathers conspicuously, and the upper tail coverts oh- 

 soletely streaked with black. A broad stripe of bright yellow passes from the 

 nostril over the eye, changing abruptly into pure white as it passes over the 

 posterior eanthus. Edges of upper and lower eyelids yellow ; that of 

 the latter more or less confluent with a small 'semilunar patch of yel- 

 low just below the eye. Chin, throat and upper part of the breast broadly 

 and uninterruptedly bright yellow, bordered on each side by streaks of black, 

 which separate it from the slaty gray of the sides of the neck ; more anteriorly 

 a black line cutting off the infra-ocular yellow crescent from the yellow of the 

 throat. Lores between eye and bill black, and the feathers of the crown 

 centrally black, most so on the forehead, less so on the occiput, producing an 

 appearence much like that of Afyiodioctes canadensis. Lesser and median 

 wing coverts colored like the back, greater coverts like the primaries ; both 

 median and greater conspicuously tipped with white, the former much the 

 most broadly. Primaries dusky ; the first three or four with an exceedingly 

 narrow margin of white ; the rest and the secondaries with somewhat pale 

 edges. Tail like the wings ; the outermost lateral rectrices white, except 

 their shafts, and a very small area at the base of the inner web, and the outer 

 web for half its length from the base ; next feather similar, but the dusky 

 area twice as large ; the third has only a small, somewhat triangular spot of 

 white near the end of the inner web. The under parts, from the termination 

 of the trenchantly defined yellow of the breast, are white ; immaculate on the 

 centre of the abdomen ; thickly streaked along the sides with large, partially
