Accurately described in 1760 by Brisson, with its habitat correctly stated, this fine species 

 remained unrecognized until a few years ago. It seems to be confined to the island of Luzon, 

 being represented in Negros by the following species. It is the first species mentioned by 

 Vieillot (Analyse, p. 41, no. 125, 1817) under his genus Dicrurus, diXiA therefore may conveniently 

 be regarded as the type, and Bonaparte's generic title Balicassius^ must fall. E. viridescens, 

 Gould, was described from a Philippine example now in Mr. Eyton's collection, and which I have 



t Adopted by Fifzinger (Fum. dcr Vdgcl, p. 198).
