429. Sterna hirundo, L. 



S.Jluviatilis, Naumann. 



Central China ; never yet observed on the coast. I have a spe- 

 cimen from Hankow. 



430. Sterna longipennis, Nordmann ; von Schrenck, Amur- 

 land, Vogel, p. 512. 



From Amoorland, probably descending into North China. I have 

 never met with it. Allied to the last, but with black bill and longer 

 wings. 



431. Sternula minuta, L. 



Visits the Chinese coast in winter. I have specimens from 

 Amoy. 



432. Sternula sinensis, Gmel. ; Swinhoe, Ibis, 1863, p. 429. 



/S. sumatrana. Raffles. 



A common summer species in Formosa, breeding in large numbers 

 on the precipitous rocky coast on the eastern side of the island. I 

 have also specimens in various stages of plumage from Hankow, 

 showing that it also breeds in Central China. I have never met 

 with it on the Chinese coast ; but from its being found in the Ma- 

 layan archipelago, I should fancy that it migrates thither in winter. 



433. Anous stolidus. 



Sterna stolida, L. 



Found in South China Sea ; breeds on the eastern rocks of For- 

 mosa, whence I have a pair.

are the only two species of Albatros found north of the line. For 

 remarks on them, see Ibis, 1863, p. 431.
