secondaries broadly tipped with pure wUte. This remarkable feature, so 

 far as the specimens at hand go to show, is entirely characteristic of this 

 plumage. 



45. Fetrochelidon lunifrons. 



First plumage : male. Top of head, back, and scapulars dark brown ; 

 collar aroimd nape, dull ashy, tinged anteriorly with rusty. Rump as in 

 adult, but paler ; forehead sprinkled with white, and with a few chestnut 

 feathers. Secondaries [broadly tipped with ferruginous. Throat white, a 

 few feathers spotted centrally with dusky. Breast and sides ashy, with a 

 rusty suflFusion, most pronounced on the latter parts. A very small area 

 of pale chestnut on the cheeks. From a specimen in my collection taken 

 at Upton, Me., July 27, 1874. ' 



46. Cotyle liparia. 



First plumage: male. Upper parts brown, each feather edged with 

 ferruginous, this edging broadest on the rump and secondaries, narrowest 

 on the crown and nape. Beneath like the adult, but with the pectoral band 

 strongly washed with ferruginous, and the throat thickly spotted with the 

 same color. In my collection, from Eye Beach, N. H., August 24, 1872. 

 Autumnal specimens have the secondaries tipped with white, but not so 

 broadly as in Tachycineta Tricolor. 



47. Ampelis cedrorum. 



First plumage: female. Above generally duller cinnamon than in 

 adult, with obscure streakings of dusky-buff ; rump grayish-brown with a 

 tinge of olive. Tail narrowly tipped with gamboge-yellow. Two secon- 

 daries on each wing slightly tipped with the red waxen appendages. En- 

 tire under parts brownish-buff, palest about anal region, deepest on throat 

 and chin ; breast and sides streaked thickly with cinnamon-brown. A 

 dull black line, starting from the nostrU, passes through the lore to the 

 eye, where it terminates, embracing, however, the anterior half of both eye- 

 lids. From a specimen iu my collection, taken at Upton, Me., August 14, 

 1874. I have seen specimens of this species in the first plumage with 

 not only the secondaries wax-tipped, but several of the tail-feathers also. 

 Nor is this homy appendage peculiar to the male, as has been stated, for 

 several undoubted females before me have it fully developed. Much va- 

 riation likewise obtains among different individuals in respect to the num- 

 ber and position of these appendages. One specimen (a male, Cambrid"e 

 March 21, 1870) has every feather of the tail conspicuously wax-tipped, in 

 addition to nine of the secondaries on each wing, while another has the 

 primaries (excepting the first three) tipped broadly with white and in the 

 centre of each white spot a smaller one of yellow.
