In the female these spots are fewer and lighter. 
25. Pericrocotus cinereus, Lafresn. 
I witnessed a small flock of these only once, and that was at 
Taiwanfoo, S.W., on the 5th September, 1861. This species was 
originally described from the Philippines. In South China it is 
only seen and heard in the seasons of migration, roaming about 
the country with its undulating flight and canary-like chirp, and 
in a day or two it has disappeared. It passes its summer in the 
North of China, occurring even in Amoorland, and in early 
autumn turns down the coast to Amoy and Canton, whence it 
wings its way across the sea, touching the south of Formosa, to 
the Philippines for its winter-quarters. 
In North Formosa I did not observe it, that being, I suppose, 
out of its direct route.
