6 Mr. J. D. D. La Touche—Field-Notes on 
air and out of range. They declared that these were the 
“ Swallows ” which occur at Kuatun in summer (see ‘ Ibis,’ 
1899, p. 431). In September, 1904, a number were seen 
flying over the paddy-fields.

I have occasionally observed Swifts which were probably 
of this species. On August 29, 1902, I saw a number of 
large Swifts—no doubt C. pacificus—going S.E. before a 
storm. They were in company with Swallows.

This species is very common in April and May in woods 
on the hills, and is also seen flying over the paddy-fields at 
dusk. It passes again in September.

The Common Cuckoo arrives towards the middle of May, 
and at the end of that month and during June is extremely 
abundant. I have often seen several individuals flying 
together, calling and pursuing one another. It may be 
heard until the end of July, but I have not noticed it in 
autumn. 
The common form at Chinkiang is the pale variety with 
white narrowly barred under parts. Its call is the same as 
that of the European bird—“ kook-koo” or ‘‘ kookook keoo.”? 
I have also a male, shot on May 26, which has dark upper 
parts. The under parts in this specimen are tinged with 
buff, the under tail-coverts are buff, and it has broad bars 
set widely apart. The wing measures 8°25 in., so that the 
bird is too large for C. intermedius. Another example, 
shot on May 13, is precisely similar to typical C. intermedius 
in all but size, the wing measuring 8°15 in. A number of 
examples of the common pale form, shot at Chinkiang, vary 
in length of wing from 7°75 to 9°2 in. (males) and from 
7°8 to 8°85 in. (females). A Cuckoo sent me from Anhwei
