Hab. Luzon, January and February (Meyer). 
Sexes, as determined by Dr. Meyer, do not differ. 
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, 
and therefore may conveniently be regarded as the type, and Bonaparte’s generic title 
Balicassius' must fall. . viridescens, Gould, was described from a Philippine example 
now in Mr. Eyton’s collection, and which I have examined. Wagler bestowed as a new 
title that of furcatus on Corvus balicassius, Linn., as seems to have been his habit when 
he altered the genus. The fact that true D. balicassius is a purely Philippine bird 
was not fully appreciated by my lamented friend the late Dr. Jerdon; for (Ibis, 1872, 
p- 119) he alludes to the Himalayan Dicrurus as being “ distinct from the Malayan 
species to which the name of balicassius was applied.” The Malayan species here 
referred to is Edolius affinis, Blyth (J. A. S. B. 1842, p. 174, “ Malay peninsula”), and 
which, after comparison, I am unable to separate from the Himalayan D. annectens, 
which is the Tephrodornis grisola, Blyth, J. A. S. B. 1843, p. 180*, and is described op. cit, 1842, p. 799. If 
Mr. G. R. Gray is right, and it can be shown that Hylocharis, Boie, 1825, was founded on the Hylocharis luscinia 
or philomela of S. Miiller, the generic title Hyloterpe will haye to fall. 
* Adopted by Fitzinger (Fam. der Vogel, p. 198).
