buff. The bill is Locustc41iiie, but the rictal bristles are fairl}- deve- 

 loped ; the upper mandible is dark, the under mandible pale. The 

 legs, feet, and claws are pale horn-colour. Length of wing 2'2 to 

 2-1 inches, tail 2-1 to 1-85, culmen 0'6 to 0-52. Third and fourth 

 primaries nearly equal and longest ; second primary generally 

 intermediate in length between the sixth and seventh, occasionally 

 between the seventh and eighth ; l)astard primary exceeding the 

 primary-coverts by 0'15 to 0'25 inch. 



After the autumn moult both the upper and under parts are more 

 rufous than in spring ; and in winter, and especially in summer, 

 much of the rufous coloration is lost by abrasion. 



Schrenck's E,eed-Warbler breeds in the valley of the Amoor, and 

 has been taken frequently in Japan, where it probably also breeds. 

 It passes through China on migration, and has been found wintering 

 in the Tenasserim Provinces.

* I have retained the name iu common use for the Greiit Reerl-Warbler, 

 contrary to the rules of the British Association, beeauee it is the name in 

 common use. Acrocephalus arundinaceus (Linn.) may be rejected under the 

 rules, because, in placing the sp»cies under the genus Turdus, llie definition 

 became so misleading as to admit of the specific nauie being applied to the 

 Common Eced- Warbler. Acrocephalus laeustris (Xaum.) is the name by which 

 it ought to be known if the rules are to be enforced. Acrocephalus junco (Pall.) 

 may be rejected on the ground of want of clear definition also, inasmuch as 

 Pallas did not remove it from the genus Turdus.
