Native names: see Prinia familiaris. 
This very good species is easily distinguished from Prinia 
polychrous (Temminck), Pl. col. 466, f. 3, 1828, by its 
smaller size, its unstreaked head and its conspicuously 
white lores, which are only in young examples of polychrous 
yellowish white. From Prinia familiaris Horsfield, which 
it resembles much more, it differs by the want of yellow 
on the under surface, by the want of white tips to the _ 
greater and median wingeoverts and also by having white 
lores, which are dark greyish brown in adult examples of 
familiaris; only in young birds and in females of familiaris 
there is a white line above the dark lores. 
Above dark greyish brown with an olive tinge, feathers 
of the forehead with darker centres; wingcoverts and quills 
dark brown, margined with olive brownish, bend of wing 
and under wingcoverts creamy-white ; tailfeathers dark brown 
with olive margins and white tips, before the latter with 
an indistinct blackish spot; lores, chin, throat and fore- 
neck white with a faint creamy tinge; rest of under sur- 
face white with a stronger creamy tinge; sides of breast 
and flanks dusky; thighs brownish white. ans orange-brown ; 
bill yellowish brown with dark grey tip; feet yellowish 
brown. Wing 52—54; tail 62—69; bill 11—18; tarso- 
met. 22 mm. Sexes alike. 
The bill is slender like that of Prinia familiaris; the bill 
of Prinia polychrous is heavier and its culmen more rounded.
