the edge of the jungle, even in the south of the island, the 

 black Drongo was abundant. It is one of the accompaniments 

 of cultivation, like the Sparrow, the Yellow Wagtails, and so forth 

 among birds, and the castor oil, the plaintain-weed, and others 

 among plants. I have brought away a pair : —

In the former the outer rectrices continue up towards the tip ; 

 in the latter they are flat.

The White-cheeked Grey Drongo was not rare among the 

 fine woods of Central Hainan. It was generally met in parties 

 of three or four. It has a loud defiant song, which it utters 

 while perched on the top of high boughs of trees or tall bam- 

 boos. This is the same species that passes up the China coast 

 to summer. I formerly applied the name leucophceus to mark 

 this bird ; but Lord Walden has lately proved that D. leucophceus, 

 Vieill., is the same as D. cineraceus (Horsf.) of Java, over which 

 designation it takes precedence. 



My single male specimen from Hainan measures : — wing 

 5*625 ; tail 5*125 ; tip of middle to tip of outer rectrix -25.

This is a race of Ashy Drongos closely allied to D. cineraceus 

 (Horsf.) of Java, with which it requires close comparison 

 before discrimination is possible. Lord Walden has founded the 

 species under the above name on a specimen from Cambodia, 

 procured by Mouhot, compared with which my Hainan speci- 

 mens are somewhat larger, and a specimen I have from Tenas- 

 serim, sent by Mr. Blyth, smaller. I have two males and one 

 female from Hainan, measuring : —
