Adult male. Top of the head black, all the feathers tipped -with 

 brown or reddish brown, a white or pale bntf stripe down the 

 middle of the head ; feathers of the mantle sandy or reddish brown, 

 each with a wide buff black-edged shaft-stripe tapering to a point, 

 and with a wide black bar or blotch on one or both webs. The 

 scapulars and feathers of the back, rump, and upper tail-coverts 

 are very similar to the mantle, but the ground-colour is generally 

 black with narrow -^^-shaped transverse bars of dirty or reddish 

 white, and the shaft-stripes are wider and confined to a line of 

 leathers down each side of the spine, forming a regular pattern. 

 The lesser, median, and secondary coverts are sandy brown, with 

 very narrow shaft-stripes and transverse bars of butf edged with 

 black. Primaries, primary-coverts, and secondaries blackish 

 brown, the former barred and mottled on the outer web, the latter 

 on both, with Iniff. Lores and superciliary stripe white, a reddish 

 or blackish-brown liand commences behind the upper angle of the 

 nostril and jiasscs tlirough the eye over the ear-coverts ; a black or 

 sometimes reddish-black band extends backwards to behind the 

 eye from the angle of the gape ; a black angle-shaped mark * 

 commences on the chin and passes down the middle of the throat, 

 the arms curving upwards to the ear-coverts. The remaining portions 

 of the sides of the head, chin, and throat are white, and usually 

 separated from the chest by an ill-defined band of black and rust- 

 colourcd spots. Chest rufous buff, with white shaits, shading into 

 whitisli buff on the rest of the underparts ; sides and Hanks reddish 

 buff, spotted with black, and with wide white black-edged shaft- 

 stripes. Tail-feathers black, tipped with whitish and barred with 

 buff. Total length (i-T inches, Aving 4-2, tail 1'5, tarsus 1. 



Youmj males resemble the adult female, but the chest has only 

 a few black spots. 



Adult female. Differs from the adult male in having no black 

 band down the middle of the throat, only the arms of the anchor- 

 sliaped mark being somewhat imperfectly represented, and the chest 

 is more or less thickly sjiotted with black. 



Hal. Europe, Asia (except the south-west corner, Siam, &c.), 

 Africa. 



* In some specimens the middle black band is very much wider than in 

 others, and covers a large part of the Ibroat. These are apparently very old 

 specimens.
