I 2 Chapman on Geothlypis trichas ignota. [January 



the coast of middle Georgia, is without date of capture, but is 

 evidently a spring bird. It differs from the type in the greater 

 extent of the ashy border which, mixed with yellowish, reaches 

 to the nape. 



Adult female in breeding plumage. — Type No. 3462. Coll. W. E. D. 

 Scott. Tarpon Springs, Florida. May 27 . 1887. Similar in color to the 

 male, but without the black mask and ash y border, the crown being rust v 

 brownish, paler on the forehead. The under surface is very similar to that 

 of the average spring male specimen of Geothlypis trichas, but the yellow- 

 is of a deeper shade. Measurements: Wing. 2.14; tail. 2.15 ; tarsus. .S^ ; 

 exposed culmen. .4$ inch. 



First plumage. — No. 3S44. Coll. W. E. D. Scott, Tarpon Springs, Florida. 

 July 16, 1SS6. Similar to young of Geotkfypis trichas in same stage of 

 plumage, but throat, breast, and upper parts of a darker color. 



Adult male in winter. Similar to adult male in the spring but darker 

 above, the ashy band bordering the black mask restricted to a narrow 

 line; crown rich rusty brown, brighter anteriorly, where also the feathers 

 have more or less ashy and yellowish bases. — and fading gradually into the 

 color of the back; abdomen somewhat paler. Measurements, — average 

 of fourteen specimens : wing. 2.20; tail, 2. 23: tarsus, .82; exposed cul- 

 men, .47 inch. 



Rc/uarks. — An examination of the types Geothlypis trichas 

 roscoe Hasbrouck, kindly loaned me for examination by Mr. 

 Hasbrouck, -hows that it is based on a bird in winter plumage. 

 That this is not the northern bird in winter plumage is apparent- 

 ly evident on comparing it with adult fall specimens of trichas 

 from the northern States, from which it may be distinguished 

 (1) by its size and much browner color above, particularly on the 

 crown; (2) by the somewhat greater width of the black mask, 

 and restriction and slightly deeper shade of its bordering ashy 

 band ; (3) by the extent and greater intensity of the colors of the 

 underparts; and by the wing formula, the first primary equalling 

 the eighth, and not the sixth as in trichas. 



A specimen from Liberty County, Georgia (U. S. Natl. Mus., 

 No. ^j.j^j, Leconte) resembles the Florida birds in coloration 

 but has the first primary somewhat longer than the average. A 

 specimen from New Orleans. Louisiana, (U. S. Natl. Mus. No. 

 90,66s, Nov. 26, Shufeldt) is fully as dark above as the Florida 

 bird, but differs in having the ashy border to the black mask wider, 

 with the yellow of the underparts somewhat lighter in color and 

 of less extent, there being consequently more white on the abdo- 

 men, and the wing formula does not agree with that of Florida
