12 REVIEW OF THE GENUS XIPHOCOLAPTES RIDGWAY. 



tinctly streaked with pale buffy (streaks about as wide as in X. promero- 

 pirhynchus) ; hind-neck and back light oiive-brown, narrowly but very 

 distiuctly streaked with pale buffy; lesser aud middle wing-coverts 

 and anteriorscapulars similar, but the more anterior lesser coverts tinged 

 with rusty ; posterior scapulars, greater aud primary coverts, and lower 

 back plain raw-umber brown, becoming more russet posteriorly, the 

 rump and upper tail-coverts inclining to rusty chestnut; tail chestnut 

 (lighter than in X.pro meropirhynchus), with shafts becoming blackish 

 in middle portion ; remiges and inner webs of primary and greater cov- 

 erts dull cinnamon-rufous or light chestnut (much less bright than in 

 X. promeropirhynchus), the outer webs of secondaries and five or six 

 outer primaries washed or overlaid on edges with light raw-umber 

 (appearing nearly uniform on the closed wing) ; inner webs of prima- 

 ries dusky at tips, this color extending for about 1.50 inches on sec- 

 ond quill, from which gradually but decidedly decreasing in extent 

 toward innermost quill. Band on side of head from (and includ- 

 ing) lores beneath eyes and across lower half of auriculars light buff, 

 the posterior portion sparsely streaked with dusky; upper portion 

 of ear-coverts more broadly streaked with dusky, forming a broken 

 postocular stripe ; above this a stripe of pale buff extending from above 

 the eyes to the occiput, broken by a few narrow, dusky streaks; malar 

 region dusky brown, marked with longitudinal broad spots or streaks 

 of light buff. Chin aud upper throat pale buff, the latter with several 

 dashes or irregular streaks of light olive-brown ; fore-neck and sides of 

 neck light olive brown, broadly streaked with pale buff, the streaks on 

 fore-neck margined laterally with dusky; chest, breast, and sides col- 

 ored aud marked like the fore neck, but buff streaks broader (averag- 

 ing about .15 of an inch) and more distinctly margined with blackish; 

 flanks raw-umber brown, less distinctly streaked; belly tawny brown, 

 marked with broad, serrated streaks of buff, margined on each side by 

 a row of distinct black, deltoid spots ; under tail-coverts somewhat 

 similarly marked, but streaks more regular aud spots much less dis- 

 tinct; under wing-coverts ochraceous, with obliquely transverse spots 

 or interrupted bars of blackish. Bill light grayish horn-color, dusky 

 at base; legs and feet grayish black. Length (skin, neck stretched), 

 13.30; wing, 5.80; tail, 5.70; culmen, 2.00; depth of bill at gonydeal 

 angle, .40; tarsus, 1.25; middle toe, 1.05. 



With almost exactly the pattern of coloration characterizing X. pro- 

 meropirhynchus, this species has a closer general resemblance, on account 

 of the prevalent olivaceous coloring, to X. ulbicollis; but the latter dif- 

 fers conspicuously in the decided black ground-color of the pileum, 

 very inncL narrower streaks on breast, etc., bars on abdomen, darker 

 chestnut of the tail, aud several other characters. It does not require 

 comparison with any other species except X. ignotus, nobis, which is 

 much more rufescent, has the stripes on the breast, etc., much less 

 regular, the throat whiter, etc.
