 The United States National Museum contains three forms or 

 species of black-bellied Copsychus from Borneo, as follows : 



(1) A wholly black bird with a black tail; only a mere trace of 

 white on the outer web of the outer tail feather near the base and a 

 white dot on the outer web of the two outer feathers at the tip ; the 

 under tail coverts wholly black. GojJsychus niger. 



(2) A black bird with the two outer tail feathers white except 

 at the extreme base and the third outer tail feather white, black 

 only basally and in a narrow border on the inner edge of the inner 

 web; the under tail coverts black with white centers. Copsychus 

 amoenus. 



(3) A black bird like the last; only the outer tail feather white, 

 except the extreme base, the second tail feather bordered with black 

 on the inner web, the third tail feather with only a triangular white 

 spot at the tip ; the under tail coverts white and the lower belly and 

 flanks mixed white and black. 



Hartert^^ says no. 3 is imnamed. All three forms have white 

 lesser wing coverts, in nos. 2 and 3 even extending on to the outer 

 web of the inner secondaries. 



Copsychus niger has a longer bill than G. avioenus; otherwise

 ers, the white edging on outer web of the inner secondaries, and
