 the breast-markings. It probably sometimes stays a little 

 latei'j as I saw on the 23rd of October, 1915, the remains of 

 a bird which had been killed by a cat.

The Eastern Great Reed-Warbler is not a common migrant 

 at Chinwangtao, Avhere I have only seen a few towards the 

 middle of May, on the 1st and 4th of June, and in antiimn 

 dnring August and September. It appears, however, to 

 breed abundantly in the Hsieh Chia Ying mars-hes, where 

 nests and eggs were brought to me at the end of June and 

 beginning of July. Tiiese resemble those taken at Chinkiang 

 (Ibis, 1906, p. 444). 



The nests are made of weeds, grasses, and grass-down. 



This Reed-Warbler was extremely common in the reed- 

 beds near Newclnvang during the summer of 1889.

The Paddy-field Reed-Warbler is evidently a rare migrant 

 at Chinwangtao, as in seven years' collecting 1 obtained but 

 one example, shot near Shauhaikuan on the lOth of June, 

 1914. Swinhoe found it breeding near Peking {Calamoherpe 

 concinnens, P. Z. S. 1870, p. 432) in numbers. Pere David 

 states that it breeds everywhere in damp spots on the Great 

 China Plain, so that it seems bkely that it will eventually be 

 found to breed in the north-east Chihli marshes. 



The measurements cf the skin mentioned above are as 

 follows: — Culmen 11 mm.; wing 57 mm.; tail GO mm.; 

 tarsus 22 mm. Total length about 130 mm.
