Stuart Baker ^- says Campephaga is preoccupied, but I can not 

 find that this is so. I would, however, restrict this name to the 

 African species and use Volvocivora Hodgson for the Asiatic birds 

 usually placed in Cmnpephaga. Lalage Boie should be restricted to 

 Lalage nigra (Forster) and its allies.

A large series of adults and immatures from Sipora and Siberut. 



The United States National Museum has a series from Pulo 

 Tuanku, Banjak Islands, Nias, South Pagi Island, and Tana Bala, 

 Batu Islands. All of these seem to belong to one form along with 

 the material from Sipora- Siberut. Comparing this series with one 

 from Borneo and Sumatra, I can detect no constant difference in 

 size or color. The males in the Borneo-Sumatran series, on an aver- 

 age, seem to have the upper and under tail coverts longer, but this is 

 not constant. 



The wings of the males measure as follows : 



Five from Siberut, 118.5-123. 



Three from Sipora, 118-122.5. 



Two from South Pagi, 124.5. 



One from Batu Islands, 121.5. 



Two from Banjak Islands, 124-125. 



One from Nias, 128.5. 



Five from Borneo and Banka, 118-122.5. 



The wings of the females measure as follows : 



Four from Siberut, 11S.&-122.5. 



One from Sipora, 117. 



One from South Pagi, 121. 



One from Banjak Islands (type of mega^yanea), 119. 



One from Nias, 121. 



Four from Borneo and Sumatra, 115.5-120.
