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.
