The general colour of the upper parts is russet-brown, each 

 feather with an obscure dark centre, most fulvous on the rump and 

 upper tail-coverts and the margins of the outside webs of the quills 

 and tail-feathers ; the wing-coverts and innermost secondaries are

 di-stinct bufRsh white, scarcely extending to the nape ; lores and 

 the feathers behind the eye russet-brown ; over each eye-stripe a 

 narrow dark band, well defined next" the eye-stripes, but gradually 

 fading into the brown of the crown. Underparts fulvous white, 

 darkest on the flanks and thighs. The bill is intermediate between 

 Acrocephalus and LoctKtella ; upper mandible dark, under mandible 

 pale. Legs, feet, and claws brown. Length of Ming 2-3 inches, tail 

 1-75, culmen 0'6. Third and fourth primaries equal and longest ;

iSwinhoe's lieed- Warbler has only been found in South China, 

 ■where it is supposed to breed. 



The British ^luseum does not possess an example of this species, 

 wiiich is only known from the type in the Swinhoe collection in 

 my possession. It was obtained at Amoy on the 20th of May, 1861.

The general colour of the upper parts is russet-brown, slightly 

 greyer on the head, quills, and tail, and most rufous on the I'ump 

 and upper tail-coverts and the margins of the outside webs of the 

 quills and tail-feathers ; the eye-stripe is narrow, grejish white, very 

 distinct, but not extending as far as the nape ; when fresh moulted 

 the (juills and tail-feathers have narrow pale edges at and near the 

 tips, wiiich are soon lost by abrasion ; the wing-coverts and innermost 

 secondaries gradually become jjaler towards the edge on their out- 

 side webs ; lores and the feathers behind the eye russet-brown ; over 

 each eye-stripe a broad dark-brown band, abruptly defined over each 

 eye-stripe, and gradually fading into the brown of the crown of the 

 head. The breast and flanks ate pale rufous-brown, shading into 

 pale buff on the centre of the belly and under tail-coverts, and into 

 nearly white on the throat and chin ; the axillaries, thighs, under 

 wing-coverts, and the inner edging of the quiUs are pale brownish
