338 On tie Chinese Species of the Genus Suthora. 



XXVI. — On the Chinese Species of the Genus Suthora. 

 By Henry Seebohm, F.Z.S. 



Mr. Frederick William Styan and I have made a careful 

 examination of the large series of Chinese Suthora, which 

 are now available for comparison, and we have arrived at the 

 following conclusions : — 



Suthora bulomachus, Swinhoe, Ibis, 1866 (not 1863, as 

 stated in the seventh volume of the ' Catalogue of the Birds 

 in the British Museum/ p. 490), p. 300. 



Suthora suffusa, Swinhoe, Proe. Zool. Soc. 1871, p. 372. 



The examination of a considerable series of these alleged 

 species from the valley of the Yangtse as far west as the 

 Ichang Gorge and as far east as the head of the Delta, from 

 Puching in the extreme north of Fokien, from Ningpo, and ' 

 from the island of Formosa has convinced us that they are 

 identical. The types of both are in my collection, that of 

 the latter from Hoopih, Upper Yangtse, differing from 

 the Formosan type in being paler in colour and in having 

 the dark streaks on the throat and breast almost obsolete. A 

 series from the Yangtse in Mr. Styan^s collection appears to 

 prove that Swinhoe's type of Suthora suffusa is merely a 

 somewhat abraded example oi Suthora bulomachus. So far as 

 is known, the northern range of this species is bounded by the 

 valley of the Yangtse, reaching its highest latitude at the head 

 of the delta near Chinkiang, about 32°, and thence trending 

 southwards along the hill-ranges to the province of Chekiang, 

 where it reaches the coast south of Hangchow Bay. This 

 species of Suthora inhabits tropical China, and has been very 

 smartly figured by Wolf on plate ix. of ' The Ibis ' for 1866. 



North of the Yangtse and in the delta of that great river 

 S. bulomachus is replaced by the following species, which 

 inhabits subtropical China. It has been figured both by 

 Gray and Gould. 



Suthora webbiana, Gray, Proc. Zool. Soc. 1852, p. 70, 

 pi. xlix. ; Gould, ' Birds of Asia,' iii. pi. 72. 



Suthora longicauda, Campbell, Ibis, 1892, p. 237. 



We are unable to discover any difference between these
