664 Staff-Surgeon K. H. Jones on Birds 
This Wagtail breeds commonly at Wei Hai Wei and Shi 
Tao, and very often places its nest in the crevice of a rock on 
the seashore, but sometimes among herbage in a nullah. 
At all times, however, this species displays a great liking 
for the vicinity of the sea. The nest is made of grass and 
lined with finer grass or horsehair. The earliest date for 
eggs is April 25tli and the latest May 19th. 
Four or five is the usual number of eggs in a clutch, but 
six were found on one occasion. The eggs are of two types, 
a brownish grey and a greenish grey. Twenty-six eggs 
from Shantung average *79 x *57 inch, and vary in length 
from *89 to*73 inch and in width from *53 to *61 inch. 
Motacilla ocularis. 
This Wagtail occurs on passage, and was observed in 
September. 
Motacilla melanope. 
The Grey Wagtail occurs abundantly on migration at 
Wei Hai Wei. As many as eighty birds were seen in one 
flock, opposite to Kyming Island, on September 14th. 
Whilst sheltering from a northerly gale, behind a sand¬ 
bank off Taku, many of these birds came on board and 
proved very useful in catching and eating the large blue¬ 
bottle flies which swarmed all over the ship to our great 
discomfort. This was during the first week of September. 
Orxolus indicus. 
Swinhoe met with this Golden Oriole at Chefoo during 
the summer months, and thought that it might breed there. 
It was observed once in June to the westward of Wei Hai Wei, 
so that Swinhoe may be correct. The great majority of 
these birds were seen on migration and particularly at 
North-East Promontory, where they were abundant during 
the first week of September. 
At Leu Kung Tao this species was only noticed once, also 
in September. Most of the birds seen at North-East 
Promontory were immature, evidently the progeny of those 
which had bred further to the north.
