tudinal clashes of dirty whitish; upper tail-coverts dull grayish-brown 

 tipped with dirty whitish, aud sometimes barred with the same, the 

 feathers with darker shaft-streaks ; lower tail-coverts very iudistiuctly 

 marked in much the same manner. Auriculars, cheeks, and throat plain 

 dirty whitish, as in the adult. 



Chid:. — General color light isabella-color, or brownish white, with an 

 umber-brown patch over the scapula, and connected with one over the 

 radins and ulna; pileum uniform umber-brown. 



Remarlis. 



These specimens form part of a very interesting collection made by 

 Dr Edward Palmer, a collector of the National Museum. 



In the adult plumage, all the contour-feathers have distinctly black 

 shafts, especially on the lower surface and upper tail-coverts; on the 

 tibire 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 most confused 

 on the upper portion of the rump. In both adult and immature stages, 

 there is considerable variation, but all within the limits of the above 

 diagnosis. 



This species resembles the P. tharus much more than P. cheriway ; 

 but it is, nevertheless, so very distinct as not to need actual com- 

 parison. The tail is entirely ditferent in its markings, the darker bars 

 being much wider than the light ones (twice as wide) on the middle 

 feathers, while each is boidered with a narrower zigzag bar of dusky ; 

 the lighter markings are, moreover, light isabella-color, instead of white, 

 as in P. tliarus, in which white forms the ground-color, over which cross 

 very narrow bars of grayish-brown. The rump and upper tail-coverts 

 are very indistinctly barred, brown being the prevailing color; while in 

 P. tharus this region is white, narrowly barred with grayish-brown. 

 The ground-color of the lower parts is light isabella-color, with imper- 

 fect, more or less sagittate, bars of brown, whereas in P. thanis these por- 

 tions are black, crossed with narrow, regularly-transverse bars of brown- 

 ish-white. The throat is light isabella-color, while in P. tharus it is 

 white. Numerous other differences might be mentioned; but they are 

 too numerous. Briefly, the more conspicuous differences between the 

 three species may be contrasted as follows : — 



P. LUTOSUS. — Scapulars plain duslcy Uroivn. Tib lev and flanlcs light isa- 

 bella-color, barred with dark brown . Wing-coverts ( middle aud greater) 

 marked with wide bars of brown and pale isabella-color, of equal width. 

 Tail-coverts and rump with broad bars of light isabella-color and 

 grayish-brown. Tail icith broad bars of pale isabella-color and grayish- 

 brown, separated by zigzag lines of dushy. Abdomen isabella-color, with 

 small sagittate bars of dark brown. 



P. THARUS. — Scapulars barred grayish-white and black. Tibice and 

 flanJcs nearly uniform blackish-brown. Wing-coverts brown, narrowly 

 barred with whitish. Tail-coverts and rump ichite, tvith narrotc bars 

 of grayish-broivn. Tail ivhite, with narrow bars of brownish-gray. 

 Abdomen blacJcish-broicn, with transverse bars of whitish. 



P. CHERIWAY. — Scapulars plain brownish-black. Tibife and flanks 

 plain black. Wing-coverts plain blackish. Tail-coverts and rump 

 plaimohite without bars. Tail as in P. tharus. Abdomen plain black.*
