 of the island.

Folylonis lutosus Ridgway, Bull. U. S. Geol. & Geog. Survey of the Territories (F. V. 

 Haydeu), No. 6, second series, p. 459. 



Sp. CH.— Wing, 15.00-16.40; tail, 10.50-ll.6o; culmen, 1.25-1.35; 

 tarsus, 3.50-3.75; middle toe, 1.80-2.10. Adult: — Pileum, lesser wing- 

 coverts, secondaries, primary-coverts, alula, terminal portion of pri- 

 maries, entire lining of the wing (including axillars), and terminal band 

 on the tail (1.00-1.60 wide) blacliish-brown, sometimes almost black; 

 auricnlars, cheeks, and throat dirty whitish, or light isabella-color. 

 Eest of tbe i^lumage marked with transverse bars of brownish-black, or 

 dark brown, and brownish white, or ligUt isabella-color, the bars most 

 regular on the lower surface (and often the upper tail-coverts), where 

 they extend uninterruptedly from the foreneck to the crissum, the bars 

 of the two colors being about equal in widtb, the dark ones fainter on 

 the crissum, narrower and more distant on the foreneck ; on the middle 

 and greater wing-coverts they are similar to those on the abdomen ; 

 on the interscapulars the dark ones are much wider than the light ones, 

 and nearly black ; on the scapulars dark brown prevails, the lighter 

 bars being almost obliterated. The basal half or more of the outer five 

 or six primaries are isabella-white, transversely mottled, or raggedly 

 barred, with grayish and dusky, the shafts clear yellowish- white. Tail, 

 except dusky terminal band, marked with ragged transverse bars of 

 brownish-gray and isabella-white, of equal widths, the bars of the two 

 colors separated by a narrower zigzag bar of dusky. Immature. — Ee- 

 miges and rectrices the same as in the adult, but the terminal band of 

 the tail narrower and less sharply defined ; pileum and lesser wing-coverts 

 dark brown, the feathers with lighter brown edges (these sometimes 

 worn off); back and scapulars didl grayish brown, the latter plain, the 

 former usually slightly variegated with lighter borders and tips to the 

 feathers. Lower parts light grayish-brown, with longitudinal dashes 

 of dirty whitish ; upper tail-coverts dull grayish brown, tipped with 

 dirty whitish, and sometimes barred with the same, the feathers with 

 darker shaft-streaks ; lower tail-coverts very indistinctly marked in 

 much the same manner. Auriculars, cheeks, and throat plain dirty 

 white, as in the adult. Pullus. — General color light isabella-color, or 

 brownish- white, with an umber-brown patch over the scapula, con- 

 nected with one over the radius and ulna; pileum uniform umber- 

 brown. 



Bemarlcs. — In the adult plumage, all the contour-feathers have dis- 

 tinctly black shafts, especially on the lower surface and upper tail- 

 coverts ; on the tibiiP and anal-region, the dark bars are smaller and 

 more faint than elsewhere, and incline to a sagittate form ; the feathers 

 of the lining of the wing are sometimes narrowly tipped with light 

 isabella-color, or tawny-brown, and the transverse bars are faintest and
