This species resembles the P. tharus much more tlian it does the P. 
cherheay, but it is nevertheless so very distinct as not to need actual 
comparison. The tail is entirely different in its markings, the darker 
bars being much wider than the light ones (twice as wide) on the middle 
feathers, while each is bordered with a narrower,zigzag bar of dusky ; 
the lighter markings are moreover light isabella-color, instead of white, 
as in P. tharus, 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 
imi)erfect, more or less sagittate, bars of brown, whereas in P. tharus 
these portions are black, crossed with narrow, regularly transverse, bars of 
brownish-white. The throat is light isabella-color, while in P. tharus it 
is white. Other differences might be mentioned, but they are too 
numerous. Briefly, the more conspicuous differences betw’een the three 
species may be contrasted as follo'ws:— 
P. LUTOSUS. —Scapulars plain dushy hroivn. Tihkv and Jlanhs light isa¬ 
bella-color, barred with dark browm. Wing-coverts (middle and 
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 ivith broad bars of pale isahella-color 
and grayish-brown, separated by zigzag lines of dushy. Abdomen isa- 
bella-eolor, with small sagittate bars of dark brown. 
P. THARUS. —Scapulars barred grayish-white and black. Tihue and 
Jlanlcs nearly uniform blaehish-brown. Wing-coverts brow’ii, narrowly 
barred with whitish. Tail-eorerts and rump lohite, with narrow bars of 
grayish-brown. Tail loliite, with narrow bars of brownish-gray. Abdo¬ 
men blaekish broH'n, with transverse bars of whitish. 
P. CIIERIWAY.— Scapulars plain brownish-black. Tibim and flanks 
plain black. AVing-coverts plain blackish. Tail-eorerts and rump 
plain white, without bars. Tail as in 1\ tharus. Abdomen plain 
black.*
